-*-a, --auth-algo <algo type>*::
+*-a, --auth-algo '<algo type>'*::
    message authentication algorithm +
    This option sets the message authentication algorithm. +
    If HMAC-SHA1 is used, the packet length is increased. The additional bytes 
    contain the authentication data. see *--auth-tag-length* for more info. +
    Possible values:
 
-   *null*;; no message authentication
-   *sha1*;; HMAC-SHA1, default value
+   'null';; no message authentication
+   'sha1';; HMAC-SHA1, default value
 
-*-b, --auth-tag-length <length>*::
+*-b, --auth-tag-length '<length>'*::
    The number of bytes to use for the auth tag. This value defaults to 10 bytes 
-   unless the *null* auth algo is used in which case it defaults to 0. 
+   unless the 'null' auth algo is used in which case it defaults to 0.
