is a helper utility that generates encrypted passwords for the Courier authentication library. The Courier authentication library is capable of using several different encryption methods for storing passwords.

DES-based encrypted password.




md5


Compute a base64-encoded
MD5
password hash.




md5raw


Compute a hexadecimal-encoded
MD5
password hash.




sha1


Compute a
SHA1
password hash.




ssha


Compute a salted
SHA1
password hash.




sha256


Compute a
SHA256
password hash.




If not specified,
method
defaults to the modified-MD5
password encryption algorithm that\*(Aqs used in Linux (note that this is different from the
"md5"
password hash method).
