We're trying to fix as many broken links as possible before modules move into collections.  This is the batch of broken links on docker modules.

NOTE: the link checker sometimes reports an error where a link actually works. Ignore those if you find them.

##### ISSUE TYPE

##### COMPONENT NAME
<!--- Write the short name of the rst file, module, plugin, task or feature below, use your best guess if unsure -->

- One can generate L(RSA,https://en.wikipedia.org/wiki/RSA_(cryptosystem)),
      L(DSA,https://en.wikipedia.org/wiki/Digital_Signature_Algorithm),
      L(ECC,https://en.wikipedia.org/wiki/Elliptic-curve_cryptography) or
      L(EdDSA,https://en.wikipedia.org/wiki/EdDSA) private keys.
    - Keys are generated in PEM format.
    - "Please note that the module regenerates private keys if they don't match
      the module's options. In particular, if you provide another passphrase
      (or specify none), change the keysize, etc., the private key will be
      regenerated. If you are concerned that this could **overwrite your private key**,
      consider using the I(backup) option."
    - 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 I(select_crypto_backend) option. Please note that the
      PyOpenSSL backend was deprecated in Ansible 2.9 and will be removed in Ansible 2.13."
requirements:
    - Either cryptography >= 1.2.3 (older versions might work as well)
    - Or pyOpenSSL
