   when encoding it. This password manager is compatible with passwords
   used in LDAP databases.
 
+* CryptPasswordManager - A manager implementing the crypt(3) hashing scheme.

+* MySQLPasswordManager - A manager implementing the digest scheme as

 It is strongly recommended to use SSHAPasswordManager, as it's the
 most secure.
