openssl_csr – Generate OpenSSL Certificate Signing Request (CSR)

New in version 2.4.


Synopsis

  • This module allows one to (re)generate OpenSSL certificate signing requests.
  • It uses the pyOpenSSL python library to interact with openssl. This module supports the subjectAltName, keyUsage, extendedKeyUsage, basicConstraints and OCSP Must Staple extensions.
  • Please note that the module regenerates existing CSR if it doesn’t match the module’s options, or if it seems to be corrupt. If you are concerned that this could overwrite your existing CSR, consider using the backup option.

Requirements

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

  • Either cryptography >= 1.3
  • Or pyOpenSSL >= 0.15

Parameters

Parameter Choices/Defaults Comments

attributes

string

added in 2.3

The attributes the resulting file or directory should have.

To get supported flags look at the man page for chattr on the target system.

This string should contain the attributes in the same order as the one displayed by lsattr.

The = operator is assumed as default, otherwise + or - operators need to be included in the string.


aliases: attr

backup

boolean

added in 2.8

  • no

  • yes

Create a backup file including a timestamp so you can get the original CSR back if you overwrote it with a new one by accident.

basic_constraints

list

added in 2.5

Indicates basic constraints, such as if the certificate is a CA.


aliases: basicConstraints

basic_constraints_critical

boolean

added in 2.5

  • no
  • yes

Should the basicConstraints extension be considered as critical.


aliases: basicConstraints_critical

common_name

string

The commonName field of the certificate signing request subject.


aliases: CN, commonName

country_name

string

The countryName field of the certificate signing request subject.


aliases: C, countryName

digest

string

Default:

"sha256"

The digest used when signing the certificate signing request with the private key.

email_address

string

The emailAddress field of the certificate signing request subject.


aliases: E, emailAddress

extended_key_usage

list

Additional restrictions (e.g. client authentication, server authentication) on the allowed purposes for which the public key may be used.


aliases: extKeyUsage, extendedKeyUsage

extended_key_usage_critical

boolean

  • no
  • yes

Should the extkeyUsage extension be considered as critical.


aliases: extKeyUsage_critical, extendedKeyUsage_critical

force

boolean

  • no

  • yes

Should the certificate signing request be forced regenerated by this ansible module.

group

string

Name of the group that should own the file/directory, as would be fed to chown.

key_usage

list

This defines the purpose (e.g. encipherment, signature, certificate signing) of the key contained in the certificate.


aliases: keyUsage

key_usage_critical

boolean

  • no
  • yes

Should the keyUsage extension be considered as critical.


aliases: keyUsage_critical

locality_name

string

The localityName field of the certificate signing request subject.


aliases: L, localityName

mode

string

The permissions the resulting file or directory should have.

For those used to /usr/bin/chmod remember that modes are actually octal numbers. You must either add a leading zero so that Ansible's YAML parser knows it is an octal number (like 0644 or 01777) or quote it (like '644' or '1777') so Ansible receives a string and can do its own conversion from string into number.

Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results.

As of Ansible 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r).

ocsp_must_staple

boolean

added in 2.5

  • no
  • yes

Indicates that the certificate should contain the OCSP Must Staple extension (https://tools.ietf.org/html/rfc7633).


aliases: ocspMustStaple

ocsp_must_staple_critical

boolean

added in 2.5

  • no
  • yes

Should the OCSP Must Staple extension be considered as critical

Note that according to the RFC, this extension should not be marked as critical, as old clients not knowing about OCSP Must Staple are required to reject such certificates (see https://tools.ietf.org/html/rfc7633#section-4).


aliases: ocspMustStaple_critical

organization_name

string

The organizationName field of the certificate signing request subject.


aliases: O, organizationName

organizational_unit_name

string

The organizationalUnitName field of the certificate signing request subject.


aliases: OU, organizationalUnitName

owner

string

Name of the user that should own the file/directory, as would be fed to chown.

path

path / required

The name of the file into which the generated OpenSSL certificate signing request will be written.

privatekey_passphrase

string

The passphrase for the private key.

This is required if the private key is password protected.

privatekey_path

path

The path to the private key to use when signing the certificate signing request.

Required if state is present.

select_crypto_backend

string

added in 2.8

  • auto

  • cryptography
  • pyopenssl

Determines which crypto backend to use.

The default choice is auto, which tries to use cryptography if available, and falls back to pyopenssl.

If set to pyopenssl, will try to use the pyOpenSSL library.

If set to cryptography, will try to use the cryptography library.

selevel

string

Default:

"s0"

The level part of the SELinux file context.

This is the MLS/MCS attribute, sometimes known as the range.

When set to _default, it will use the level portion of the policy if available.

serole

string

The role part of the SELinux file context.

When set to _default, it will use the role portion of the policy if available.

setype

string

The type part of the SELinux file context.

When set to _default, it will use the type portion of the policy if available.

seuser

string

The user part of the SELinux file context.

By default it uses the system policy, where applicable.

When set to _default, it will use the user portion of the policy if available.

state

string

  • absent
  • present

Whether the certificate signing request should exist or not, taking action if the state is different from what is stated.

state_or_province_name

string

The stateOrProvinceName field of the certificate signing request subject.


aliases: ST, stateOrProvinceName

subject

dictionary

added in 2.5

Key/value pairs that will be present in the subject name field of the certificate signing request.

If you need to specify more than one value with the same key, use a list as value.

subject_alt_name

list

SAN extension to attach to the certificate signing request.

This can either be a 'comma separated string' or a YAML list.

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

Note that if no SAN is specified, but a common name, the common name will be added as a SAN except if useCommonNameForSAN is set to false.


aliases: subjectAltName

subject_alt_name_critical

boolean

  • no
  • yes

Should the subjectAltName extension be considered as critical.


aliases: subjectAltName_critical

unsafe_writes

boolean

added in 2.2

  • no

  • yes

Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target file.

By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, but sometimes systems are configured or just broken in ways that prevent this. One example is docker mounted files, which cannot be updated atomically from inside the container and can only be written in an unsafe manner.

This option allows Ansible to fall back to unsafe methods of updating files when atomic operations fail (however, it doesn't force Ansible to perform unsafe writes).

IMPORTANT! Unsafe writes are subject to race conditions and can lead to data corruption.

use_common_name_for_san

boolean

added in 2.8

  • no
  • yes

If set to yes, the module will fill the common name in for subject_alt_name with DNS: prefix if no SAN is specified.


aliases: useCommonNameForSAN

version

integer

Default:

1

The version of the certificate signing request.

The only allowed value according to RFC 2986 is 1.



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.
