community.crypto.openssl_signature – Sign data with openssl¶
Note
This plugin is part of the community.crypto collection (version 1.6.1).
To install it use: ansible-galaxy collection install community.crypto
.
To use it in a playbook, specify: community.crypto.openssl_signature
.
New in version 1.1.0: of community.crypto
Synopsis¶
This module allows one to sign data using a private key.
The module can use the cryptography Python library, or the pyOpenSSL Python library. By default, it tries to detect which one is available. This can be overridden with the select_crypto_backend option. Please note that the PyOpenSSL backend was deprecated in Ansible 2.9 and will be removed in community.crypto 2.0.0.
Requirements¶
The below requirements are needed on the host that executes this module.
Either cryptography >= 1.4 (some key types require newer versions)
Or pyOpenSSL >= 0.11 (Ed25519 and Ed448 keys are not supported with this backend)
Parameters¶
Parameter | Choices/Defaults | Comments |
---|---|---|
path
path
/ required
|
The file to sign.
This file will only be read and not modified.
|
|
privatekey_content
string
|
The content of the private key to use when signing the certificate signing request.
Either privatekey_path or privatekey_content must be specified, but not both.
|
|
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.
Either privatekey_path or privatekey_content must be specified, but not both.
|
|
select_crypto_backend
string
|
|
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. |
Notes¶
Note
When using the
cryptography
backend, the following key types require at least the followingcryptography
version: RSA keys:cryptography
>= 1.4 DSA and ECDSA keys:cryptography
>= 1.5 ed448 and ed25519 keys:cryptography
>= 2.6
