AUTHPASSWD(1)

NAME
authpasswd - Generate login passwords

SYNOPSIS

authpasswd [method]

DESCRIPTION

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:

crypt
    Use the traditional 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's used in Linux (note that this is different from the “md5” password hash method).
