Vault PKI

Vault PKI

OpenSSL это очень просто (нет)

Развертывание PKI на основе Vault

Установка Vault

Предполагается что Vault уже установлен и настроен

PKI

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

• ttl="262800h" - 30 лет
• В теории возможно использовать пре-созданный CA или даже цепочку - смотреть тут: https://groups.google.com/g/vault-tool/c/y4IcgiLBG4c

Parameters

• 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.
