authpasswd — Generate login passwords
authpasswd [method]
authpasswd
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. authpasswd issues a
password prompt. Enter the same password twice (for
verification purposes). authpasswd computes and
prints the encrypted password. The encrypted password can be
inserted verbatim into the appropriate account record that's
processed by the authentication library's authmysql, authpgsql, authsqlite, or authldap module.
method may be
set to one of the following literals:
Use the traditional DES-based encrypted password.
Compute a base64-encoded MD5 password hash.
Compute a hexadecimal-encoded MD5 password hash.
Compute a SHA1 password hash.
Compute a salted SHA1 password hash.
Compute a SHA256 password hash.
If not specified, method defaults to the
modified-MD5 password
encryption algorithm that's used in Linux (note that this is
different from the “md5” password hash method).
