New in community.crypto 1.3.0

Synopsis

  • Please note that the module regenerates an existing CSR if it does not match the module’s options, or if it seems to be corrupt.

  • This module allows one to (re)generate OpenSSL certificate signing requests.

  • This module supports the subjectAltName, keyUsage, extendedKeyUsage, basicConstraints and OCSP Must Staple extensions.

Requirements

The below requirements are needed on the host that executes this module.

  • cryptography >= 1.3

Parameters

Parameter

Comments

authority_cert_issuer

list / elements=string

Names that will be present in the authority cert issuer field of the certificate signing request.

Values must be prefixed by their options. (i.e., email, URI, DNS, RID, IP, dirName, otherName and the ones specific to your CA)

Example: DNS:ca.example.org

If specified, authority_cert_serial_number must also be specified.

Please note that commercial CAs ignore this value, respectively use a value of their own choice. Specifying this option is mostly useful for self-signed certificates or for own CAs.

Note that this is only supported if the cryptography backend is used!

The AuthorityKeyIdentifier extension will only be added if at least one of authority_key_identifier, authority_cert_issuer and authority_cert_serial_number is specified.

authority_cert_serial_number

integer

The authority cert serial number.

If specified, authority_cert_issuer must also be specified.

Note that this is only supported if the cryptography backend is used!

Please note that commercial CAs ignore this value, respectively use a value of their own choice. Specifying this option is mostly useful for self-signed certificates or for own CAs.

The AuthorityKeyIdentifier extension will only be added if at least one of authority_key_identifier, authority_cert_issuer and authority_cert_serial_number is specified.

Attributes

Attribute

Support

Description

check_mode

Support: full

Can run in check_mode and return changed status prediction without modifying target.

diff_mode

Support: full

Will return details on what has changed (or possibly needs changing in check_mode), when in diff mode.

Notes

Note

  • If the certificate signing request already exists it will be checked whether subjectAltName, keyUsage, extendedKeyUsage and basicConstraints only contain the requested values, whether OCSP Must Staple is as requested, and if the request was signed by the given private key.
