Description:

def info(name):
    '''
    Return information about a certificate

    .. note::
        Will output tls.cert_info if that's available, or OpenSSL text if not

    :param name: CommonName of cert

    CLI example:

    .. code-block:: bash

        salt 'gitlab.example.com' acme.info dev.example.com
    '''
    cert_file = _cert_file(name, 'cert')
    # Use the salt module if available
    if 'tls.cert_info' in __salt__:
        cert_info = __salt__['tls.cert_info'](cert_file)
        # Strip out the extensions object contents;
        # these trip over our poor state output
        # and they serve no real purpose here anyway
        cert_info['extensions'] = cert_info['extensions'].keys()
        return cert_info
    # Cobble it together using the openssl binary
    openssl_cmd = 'openssl x509 -in {0} -noout -text'.format(cert_file)
    return __salt__['cmd.run'](openssl_cmd, output_loglevel='quiet')
