Логика работы (кратко)
  +
* Создается несколько инстансов PKI внутри одного процесса Vault (для большей безопастности)
  +
* Корневой сертефикат выписывается корневым PKI
  +
** Кроме прочего - он может быть удален из волта, закрыт в сейфе и т п для безопастности так как используется только для создания промежуточного СА
  +
* этот сертификат (он НЕ является секретным) распространяется по всем нодам и используется для проверки
  +
* этим сертификатом подписвается промежуточный CA
  +
* промежуточный CA подписывает клиентские сертификаты
  +
  +
Кроме того можно удлинить эту цепочку используя уже готовый СА и промежуточный СА и импортировав их в Vault (но примера тут нет - я не делал)

==Политики==
  +
  +
* По сути политики определяют права доступа ТОКЕНА к определнному пути. Токен же выдается при логине - т е в простейшем случае политики должны назначаться на пользователя (авторизация по логину/паролю)
  +
  +
Для доступа к ролям создаем 2 файла с политиками:
  +
===Политика для серверных сертефикатов===
  +
<PRE>
  +
example-dot-home-server-crt-policy.hlc
  +
</PRE>
  +
<PRE>
  +
path "pki_intermediate_ca/issue/example-dot-home-server-crt"
  +
{
  +
capabilities = ["read", "create", "list", "update"]
  +
}
  +
</PRE>
  +
===Политика для клиентских сертефикатов===
  +
<PRE>
  +
example-dot-home-client-crt-policy.hlc
  +
</PRE>
  +
<PRE>
  +
path "pki_intermediate_ca/issue/example-dot-home-client-crt"
  +
{
  +
capabilities = ["read", "create", "list", "update"]
  +
}
  +
</PRE>
  +
  +
===Создание политик из файлов===
  +
<PRE>
  +

  +
</PRE>
  +

  +
{
  +
capabilities = ["read", "create", "list", "update"]
  +
}
  +
</PRE>
  +
  +
==Привязка политик к пользователям==
  +
* Пользователи с логином и паролем хорошо подходят для тестирования - в реальных окружениях будет использоваться что-то дроугое, сервисные аккаунты или еще что-то.
  +
* Включить авторизацию по логину/паролю нужно заранее (https://noname.com.ua/mediawiki/index.php/Vault)
  +
===Просмотр пользователей===
  +
<PRE>
  +
vault list auth/userpass/users
  +
</PRE>
  +
===Создание пользователей===
  +
* Политики перечисляются через запятую (что не очевидно)
  +
* Имена пользователей "говорят" о их назначении
  +
* Пароли простые для тестирования но разные у разных пользователей (для того что бы не допустить ошибок при тестировании и не перепутать пользователя)
  +

==Параметры сертификатов==
  +
* <B>name</B> (string: <required>) – Specifies the name of the role to create. This is part of the request URL.
  +
  +
* <B>ttl</B> (string: "") – Specifies the Time To Live value provided as a string duration with time suffix. Hour is the largest suffix. If not set, uses the system default value or the value of max_ttl, whichever is shorter.
  +
  +
* <B>max_ttl</B> (string: "") – Specifies the maximum Time To Live provided as a string duration with time suffix. Hour is the largest suffix. If not set, defaults to the system maximum lease TTL.
  +
  +
* <B>allow_localhost</B> (bool: true) – Specifies if clients can request certificates for localhost as one of the requested common names. This is useful for testing and to allow clients on a single host to talk securely.
  +
  +
* <B>allowed_domains</B> (list: []) – Specifies the domains of the role. This is used with the allow_bare_domains and allow_subdomains options.
  +
  +
* <B>allowed_domains_template</B> ()bool: false) – When set, allowed_domains may contain templates, as with ACL Path Templating.
  +
  +
* <B>allow_bare_domains</B> (bool: false) – Specifies if clients can request certificates matching the value of the actual domains themselves; e.g. if a configured domain set with allowed_domains is example.com, this allows clients to actually request a certificate containing the name example.com as one of the DNS values on the final certificate. In some scenarios, this can be considered a security risk.
  +
  +
* <B>allow_subdomains</B> (bool: false) – Specifies if clients can request certificates with CNs that are subdomains of the CNs allowed by the other role options. This includes wildcard subdomains. For example, an allowed_domains value of example.com with this option set to true will allow foo.example.com and bar.example.com as well as *.example.com. This is redundant when using the allow_any_name option.
  +
  +
* <B>allow_glob_domains</B> (bool: false) - Allows names specified in allowed_domains to contain glob patterns (e.g. ftp*.example.com). Clients will be allowed to request certificates with names matching the glob patterns.
  +
  +
* <B>allow_any_name</B> (bool: false) – Specifies if clients can request any CN. Useful in some circumstances, but make sure you understand whether it is appropriate for your installation before enabling it.
  +
  +
* <B>enforce_hostnames</B> (bool: true) – Specifies if only valid host names are allowed for CNs, DNS SANs, and the host part of email addresses.
  +
  +
* <B>allow_ip_sans</B> (bool: true) – Specifies if clients can request IP Subject Alternative Names. No authorization checking is performed except to verify that the given values are valid IP addresses.
  +
  +
* <B>allowed_uri_sans</B> (string: "") - Defines allowed URI Subject Alternative Names. No authorization checking is performed except to verify that the given values are valid URIs. This can be a comma-delimited list or a JSON string slice. Values can contain glob patterns (e.g. spiffe://hostname/*).
  +
  +
* <B>allowed_other_sans</B> (string: "") – Defines allowed custom OID/UTF8-string SANs. This can be a comma-delimited list or a JSON string slice, where each element has the same format as OpenSSL: <oid>;<type>:<value>, but the only valid type is UTF8 or UTF-8. The value part of an element may be a * to allow any value with that OID. Alternatively, specifying a single * will allow any other_sans input.
  +
  +
* <B>server_flag</B> (bool: true) – Specifies if certificates are flagged for server use.
  +
  +
* <B>client_flag</B> (bool: true) – Specifies if certificates are flagged for client use.
  +
  +
* <B>code_signing_flag</B> (bool: false) – Specifies if certificates are flagged for code signing use.
  +
  +
* <B>email_protection_flag</B> (bool: false) – Specifies if certificates are flagged for email protection use.
  +
  +
* <B>key_type</B> (string: "rsa") – Specifies the type of key to generate for generated private keys and the type of key expected for submitted CSRs. Currently, rsa and ec are supported, or when signing CSRs any can be specified to allow keys of either type and with any bit size (subject to > 1024 bits for RSA keys).
  +
  +
* <B>key_bits</B> (int: 2048) – Specifies the number of bits to use for the generated keys. This will need to be changed for ec keys, e.g., 224, 256, 384 or 521.
  +
  +
* <B>key_usage</B> (list: ["DigitalSignature", "KeyAgreement", "KeyEncipherment"]) – Specifies the allowed key usage constraint on issued certificates. Valid values can be found at https://golang.org/pkg/crypto/x509/#KeyUsage - simply drop the KeyUsage part of the value. Values are not case-sensitive. To specify no key usage constraints, set this to an empty list.
  +
  +
* <B>ext_key_usage</B> (list: []) – Specifies the allowed extended key usage constraint on issued certificates. Valid values can be found at https://golang.org/pkg/crypto/x509/#ExtKeyUsage - simply drop the ExtKeyUsage part of the value. Values are not case-sensitive. To specify no key usage constraints, set this to an empty list.
  +
  +
* <B>ext_key_usage_oids</B> (string: "") - A comma-separated string or list of extended key usage oids.
  +
  +
* <B>use_csr_common_name</B> (bool: true) – When used with the CSR signing endpoint, the common name in the CSR will be used instead of taken from the JSON data. This does not include any requested SANs in the CSR; use use_csr_sans for that.
  +
  +
* <B>use_csr_sans</B> (bool: true) – When used with the CSR signing endpoint, the subject alternate names in the CSR will be used instead of taken from the JSON data. This does not include the common name in the CSR; use use_csr_common_name for that.
  +
  +
* <B>ou</B> (string: "") – Specifies the OU (OrganizationalUnit) values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  +
  +
* <B>organization</B> (string: "") – Specifies the O (Organization) values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  +
  +
* <B>country</B> (string: "") – Specifies the C (Country) values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  +
  +
* <B>locality</B> (string: "") – Specifies the L (Locality) values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  +
  +
* <B>province</B> (string: "") – Specifies the ST (Province) values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  +
  +
* <B>street_address</B> (string: "") – Specifies the Street Address values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  +
  +
* <B>postal_code</B> (string: "") – Specifies the Postal Code values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  +
  +
* <B>serial_number</B> (string: "") – Specifies the Serial Number, if any. Otherwise Vault will generate a random serial for you. If you want more than one, specify alternative names in the alt_names map using OID 2.5.4.5.
  +
  +
* <B>generate_lease</B> (bool: false) – Specifies if certificates issued/signed against this role will have Vault leases attached to them. Certificates can be added to the CRL by vault revoke <lease_id> when certificates are associated with leases. It can also be done using the pki/revoke endpoint. However, when lease generation is disabled, invoking pki/revoke would be the only way to add the certificates to the CRL.
  +
  +
* <B>no_store</B> (bool: false) – If set, certificates issued/signed against this role will not be stored in the storage backend. This can improve performance when issuing large numbers of certificates. However, certificates issued in this way cannot be enumerated or revoked, so this option is recommended only for certificates that are non-sensitive, or extremely short-lived. This option implies a value of false for generate_lease.
  +
  +
* <B>require_cn</B> (bool: true) - If set to false, makes the common_name field optional while generating a certificate.
  +
  +
* <B>policy_identifiers</B> (list: []) – A comma-separated string or list of policy OIDs.
  +
  +
* <B>basic_constraints_valid_for_non_ca</B> (bool: false) - Mark Basic Constraints valid when issuing non-CA certificates.
  +
  +
* <B>not_before_duration</B> (duration: "30s") – Specifies the duration by which to backdate the NotBefore property.

Vault PKI

OpenSSL это очень просто (нет)

Развертывание PKI на основе Vault

Установка Vault

Предполагается что Vault уже установлен и настроен

PKI

Логика работы (кратко)

  • Создается несколько инстансов PKI внутри одного процесса Vault (для большей безопастности)
  • Корневой сертефикат выписывается корневым PKI
    • Кроме прочего - он может быть удален из волта, закрыт в сейфе и т п для безопастности так как используется только для создания промежуточного СА
  • этот сертификат (он НЕ является секретным) распространяется по всем нодам и используется для проверки
  • этим сертификатом подписвается промежуточный CA
  • промежуточный CA подписывает клиентские сертификаты

Кроме того можно удлинить эту цепочку используя уже готовый СА и промежуточный СА и импортировав их в Vault (но примера тут нет - я не делал)

Включить PKI для корневого сертификата

vault secrets enable \
    -path=pki_root_ca \
    -description="PKI Root CA" \
    -max-lease-ttl="262800h" \
    pki

Создание корневого сертефиката (CA)

Конфигурация Vault

  • ВАЖНО: Тип определяет будет ли показан ключ от сертификата. В случае internal ключ показа не будет и сертификат можно будет использовать только в Vault
TYPE="exported"
#TYPE="internal"

vault write -format=json pki_root_ca/root/generate/${TYPE} \
    common_name="Root Certificate Authority for Home Network" \
    country="Ukraine" \
    locality="Kharkov" \
    street_address="Lui Pastera St. 322, app. 131" \
    postal_code="61172" \
    organization="Home Network" \
    ou="IT" \
    ttl="262800h" > pki-root-ca.json

Конфигурация Vault для использования промежуточного CA

Загрузка промежуточного сертефиката

vault write pki_intermediate_ca/intermediate/set-signed \
    certificate=@intermediateCA.cert.pem

Configure URLs

Работа с PKI

Создание пользователей и ролей не относится непосредсвенно к настройке PKI но доьбавлено для полноты так как все равно надо настроить =)

Роли

По сути роли здесь - это Путь к которому нужно будет дать доступ с помошью политик

Политики

  • По сути политики определяют права доступа ТОКЕНА к определнному пути. Токен же выдается при логине - т е в простейшем случае политики должны назначаться на пользователя (авторизация по логину/паролю)

Для доступа к ролям создаем 2 файла с политиками:

Политика для серверных сертефикатов

example-dot-home-server-crt-policy.hlc

path "pki_intermediate_ca/issue/example-dot-home-server-crt"
{
  capabilities = ["read", "create", "list", "update"]
}

Политика для клиентских сертефикатов

example-dot-home-client-crt-policy.hlc

path "pki_intermediate_ca/issue/example-dot-home-client-crt"
{
  capabilities = ["read", "create", "list", "update"]
}

Создание политик из файлов

vault policy write example-dot-home-server-crt-policy  example-dot-home-server-crt-policy.hlc

vault policy write example-dot-home-client-crt-policy  example-dot-home-client-crt-policy.hlc

Проверка созданных политик

vault policy list
default
example-dot-home-client-crt-policy
example-dot-home-server-crt-policy
root

vault policy read example-dot-home-server-crt-policy
path "pki_intermediate_ca/issue/example-dot-home-server-crt"
{
  capabilities = ["read", "create", "list", "update"]
}

vault policy read example-dot-home-client-crt-policy
path "pki_intermediate_ca/issue/example-dot-home-client-crt"
{
  capabilities = ["read", "create", "list", "update"]
}

Привязка политик к пользователям

  • Пользователи с логином и паролем хорошо подходят для тестирования - в реальных окружениях будет использоваться что-то дроугое, сервисные аккаунты или еще что-то.
  • Включить авторизацию по логину/паролю нужно заранее (https://noname.com.ua/mediawiki/index.php/Vault)

Просмотр пользователей

vault list  auth/userpass/users

Создание пользователей

  • Политики перечисляются через запятую (что не очевидно)
  • Имена пользователей "говорят" о их назначении
  • Пароли простые для тестирования но разные у разных пользователей (для того что бы не допустить ошибок при тестировании и не перепутать пользователя)

Пользователь для получения серверных сертификатов

vault \
  write auth/userpass/users/example-dot-home-server-crt-user \
  password=server \
  policies="example-dot-home-server-crt-policy,default"

Пользователь для получения клиентских сертификатов

vault \
  write auth/userpass/users/example-dot-home-client-crt-user \
  password=client \
  policies="example-dot-home-client-crt-policy,default"

Проверка сертификатов с Nginx

Для проверки работы сертификатов настроим nginx как proxy. в качестве бекенда выступает сам Vault

Настройка Nginx

Предварительный конфиг виртуалхоста (пока не загружаю - так как ни ключа ни сертификата пока нет) 

server {
    listen 8202 default_server ssl;
    root /var/www/html;
    server_name vault.home vault.local;

    }
}

Настройка Vault

Создание роли

Роль ждя сертификата для домена vault.home 

vault write pki_intermediate_ca/roles/vault-dot-home-server-crt \
    country="Ukraine" \
    locality="Kharkov" \
    street_address="Lui Pastera st 322 app. 311"\

    enforce_hostnames=true \
    key_usage="DigitalSignature,KeyEncipherment" \
    ext_key_usage="ServerAuth" \
    require_cn=true

Создание политик

  • Файл vault-dot-home-server-crt-policy.hlc
path "pki_intermediate_ca/issue/vault-dot-home-server-crt"
{
  capabilities = ["read", "create", "list", "update"]
}

vault \
    policy \
        write \
            vault-dot-home-server-crt-policy \
            vault-dot-home-server-crt-policy.hlc

Создание пользователя для работы с сертефикатами

Еще раз подчеркну что пользователи используются тут ТОЛЬКО В ТЕСТОВЫХ ЦЕЛЯХ.

Существующие пользователи

vault list  auth/userpass/users
Keys
----
example-dot-home-any-crt-user
example-dot-home-client-crt-user
example-dot-home-server-crt-user

Новый пользователь с политикой для домена vault.home

  • username: vault-dot-home-server-crt-user
  • password: vault
  • политики: vault-dot-home-server-crt-policy и default
vault \
  write auth/userpass/users/vault-dot-home-server-crt-user \
  password=vault \
  policies="vault-dot-home-server-crt-policy,default"

Проверка

export VAULT_ADDR="http://vault.home:8200"
unset VAULT_TOKEN


vault \
    login \
    -method=userpass \
    username=vault-dot-home-server-crt-user \
    password=vault


vault \
    write \
    -format=json pki_intermediate_ca/issue/vault-dot-home-server-crt \
    common_name="vault.home" \
    ttl="43800h" > vault.home.crt

Подготовка Consul Template

Установка

Так или иначе в зависимости от системы (это пример из интернета). Для arm версия другая. 

$ wget https://releases.hashicorp.com/consul-template/0.19.5/consul-template_0.19.5_linux_amd64.zip
$ apt-get install unzip
$ unzip consul-template_0.19.5_linux_amd64.zip
$ mv consul-template /user/local/bin

Темплейты для сертефиката и ключа

  • /etc/consul-template.d/templates/vault-cert.tpl
{{- /* vault-cert.tpl */ -}}
{{ with secret "pki_intermediate_ca/issue/vault-dot-home-server-crt" "common_name=vault.home" "ttl=2m" }}
{{ .Data.certificate }}
{{ .Data.issuing_ca }}{{ end }}


  • /etc/consul-template.d/templates/vault-key.tpl
{{- /* vault-dot-home-key.tpl */ -}}
{{ with secret "pki_intermediate_ca/issue/vault-dot-home-server-crt" "common_name=vault.home" "ttl=2m"}}
{{ .Data.private_key }}{{ end }}

Конфигурация consul-template

  • /etc/consul-template.d/configs/nginx-vault.hcl

token пропущен так как авторизация через логин/пароль и токен получается динамически 

vault {
  address = "http://vault.home:8200"
#  token = "<TOKEN_HERE>"
  renew_token = true

  retry {
    enabled = true
    attempts = 5
    backoff = "250ms"
  }
}

template {
  source      = "/etc/consul-template.d/templates/vault-cert.tpl"
  destination = "/etc/nginx/certs/vault.crt"
  perms       = "0600"
  command     = "systemctl reload nginx"
}

template {
  source      = "/etc/consul-template.d/templates/vault-key.tpl"
  destination = "/etc/nginx/certs/vault.key"
  perms       = "0600"
  command     = "systemctl reload nginx"
}

Тестовый запуск

Скрипт 

#!/bin/bash

VAULT_TOKEN=$(vault \
    login \
    -method=userpass \
    username=vault-dot-home-server-crt-user \
    password=vault \
    --format=json | jq -r .auth.client_token
)


#echo ${VAULT_TOKEN}

export VAULT_TOKEN=${VAULT_TOKEN}

/usr/local/consul/bin/consul-template \
    -config /etc/consul-template.d/configs/nginx-vault.hcl

systemd unit

Создаю Unit-file:

  • имя файла /etc/systemd/system/consul-template-vault-nginx.service
  • Юнит "с дебагом"
  • Кроме всего прочего выводит переменные окружения (что бы убедиться что они нормально загружаются) и переменные systemd
  • Токен сохраняется во временном файле и потом отттуда попадает в переменные окружения

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

Добавление корневого сертификата

  • Внимание - расширение файла ВАЖНО для утилиты update-ca-certificates. Если оставить PEM то сертификат не будет добавлен.
  • rootCA.pem - файл корневого сертификата (см выше по тексту)
  • Корневой сертификат (НО НЕ КЛЮЧ!) всегда можно получить curl http://vault.home:8200/v1/pki_root_ca/ca/pem 
cp rootCA.pem /usr/local/share/ca-certificates/rootCA.crt

Параметры сертификатов

  • name (string: <required>) – Specifies the name of the role to create. This is part of the request URL.
  • ttl (string: "") – Specifies the Time To Live value provided as a string duration with time suffix. Hour is the largest suffix. If not set, uses the system default value or the value of max_ttl, whichever is shorter.
  • max_ttl (string: "") – Specifies the maximum Time To Live provided as a string duration with time suffix. Hour is the largest suffix. If not set, defaults to the system maximum lease TTL.
  • allow_localhost (bool: true) – Specifies if clients can request certificates for localhost as one of the requested common names. This is useful for testing and to allow clients on a single host to talk securely.
  • allowed_domains (list: []) – Specifies the domains of the role. This is used with the allow_bare_domains and allow_subdomains options.
  • allowed_domains_template ()bool: false) – When set, allowed_domains may contain templates, as with ACL Path Templating.
  • allow_bare_domains (bool: false) – Specifies if clients can request certificates matching the value of the actual domains themselves; e.g. if a configured domain set with allowed_domains is example.com, this allows clients to actually request a certificate containing the name example.com as one of the DNS values on the final certificate. In some scenarios, this can be considered a security risk.
  • allow_subdomains (bool: false) – Specifies if clients can request certificates with CNs that are subdomains of the CNs allowed by the other role options. This includes wildcard subdomains. For example, an allowed_domains value of example.com with this option set to true will allow foo.example.com and bar.example.com as well as *.example.com. This is redundant when using the allow_any_name option.
  • allow_glob_domains (bool: false) - Allows names specified in allowed_domains to contain glob patterns (e.g. ftp*.example.com). Clients will be allowed to request certificates with names matching the glob patterns.
  • allow_any_name (bool: false) – Specifies if clients can request any CN. Useful in some circumstances, but make sure you understand whether it is appropriate for your installation before enabling it.
  • enforce_hostnames (bool: true) – Specifies if only valid host names are allowed for CNs, DNS SANs, and the host part of email addresses.
  • allow_ip_sans (bool: true) – Specifies if clients can request IP Subject Alternative Names. No authorization checking is performed except to verify that the given values are valid IP addresses.
  • allowed_uri_sans (string: "") - Defines allowed URI Subject Alternative Names. No authorization checking is performed except to verify that the given values are valid URIs. This can be a comma-delimited list or a JSON string slice. Values can contain glob patterns (e.g. spiffe://hostname/*).
  • allowed_other_sans (string: "") – Defines allowed custom OID/UTF8-string SANs. This can be a comma-delimited list or a JSON string slice, where each element has the same format as OpenSSL: <oid>;<type>:<value>, but the only valid type is UTF8 or UTF-8. The value part of an element may be a * to allow any value with that OID. Alternatively, specifying a single * will allow any other_sans input.
  • server_flag (bool: true) – Specifies if certificates are flagged for server use.
  • client_flag (bool: true) – Specifies if certificates are flagged for client use.
  • code_signing_flag (bool: false) – Specifies if certificates are flagged for code signing use.
  • email_protection_flag (bool: false) – Specifies if certificates are flagged for email protection use.
  • key_type (string: "rsa") – Specifies the type of key to generate for generated private keys and the type of key expected for submitted CSRs. Currently, rsa and ec are supported, or when signing CSRs any can be specified to allow keys of either type and with any bit size (subject to > 1024 bits for RSA keys).
  • key_bits (int: 2048) – Specifies the number of bits to use for the generated keys. This will need to be changed for ec keys, e.g., 224, 256, 384 or 521.
  • key_usage (list: ["DigitalSignature", "KeyAgreement", "KeyEncipherment"]) – Specifies the allowed key usage constraint on issued certificates. Valid values can be found at https://golang.org/pkg/crypto/x509/#KeyUsage - simply drop the KeyUsage part of the value. Values are not case-sensitive. To specify no key usage constraints, set this to an empty list.
  • ext_key_usage (list: []) – Specifies the allowed extended key usage constraint on issued certificates. Valid values can be found at https://golang.org/pkg/crypto/x509/#ExtKeyUsage - simply drop the ExtKeyUsage part of the value. Values are not case-sensitive. To specify no key usage constraints, set this to an empty list.
  • ext_key_usage_oids (string: "") - A comma-separated string or list of extended key usage oids.
  • use_csr_common_name (bool: true) – When used with the CSR signing endpoint, the common name in the CSR will be used instead of taken from the JSON data. This does not include any requested SANs in the CSR; use use_csr_sans for that.
  • use_csr_sans (bool: true) – When used with the CSR signing endpoint, the subject alternate names in the CSR will be used instead of taken from the JSON data. This does not include the common name in the CSR; use use_csr_common_name for that.
  • ou (string: "") – Specifies the OU (OrganizationalUnit) values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  • organization (string: "") – Specifies the O (Organization) values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  • country (string: "") – Specifies the C (Country) values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  • locality (string: "") – Specifies the L (Locality) values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  • province (string: "") – Specifies the ST (Province) values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  • street_address (string: "") – Specifies the Street Address values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  • postal_code (string: "") – Specifies the Postal Code values in the subject field of issued certificates. This is a comma-separated string or JSON array.
  • serial_number (string: "") – Specifies the Serial Number, if any. Otherwise Vault will generate a random serial for you. If you want more than one, specify alternative names in the alt_names map using OID 2.5.4.5.
  • generate_lease (bool: false) – Specifies if certificates issued/signed against this role will have Vault leases attached to them. Certificates can be added to the CRL by vault revoke <lease_id> when certificates are associated with leases. It can also be done using the pki/revoke endpoint. However, when lease generation is disabled, invoking pki/revoke would be the only way to add the certificates to the CRL.
  • no_store (bool: false) – If set, certificates issued/signed against this role will not be stored in the storage backend. This can improve performance when issuing large numbers of certificates. However, certificates issued in this way cannot be enumerated or revoked, so this option is recommended only for certificates that are non-sensitive, or extremely short-lived. This option implies a value of false for generate_lease.
  • require_cn (bool: true) - If set to false, makes the common_name field optional while generating a certificate.
  • policy_identifiers (list: []) – A comma-separated string or list of policy OIDs.
  • basic_constraints_valid_for_non_ca (bool: false) - Mark Basic Constraints valid when issuing non-CA certificates.
  • not_before_duration (duration: "30s") – Specifies the duration by which to backdate the NotBefore property.
