    '''

    .. code-block:: text

        n  Don't update file; display results on stdout.
        m  Force MD5 hashing of the password (default).
        d  Force CRYPT(3) hashing of the password.
        p  Do not hash the password (plaintext).
        s  Force SHA1 hashing of the password.

    CLI Examples:

    .. code-block:: bash

        salt '*' apache.useradd /etc/httpd/htpasswd larry badpassword
        salt '*' apache.useradd /etc/httpd/htpasswd larry badpass opts=ns
