# authpasswd(1)

Generate login passwords

## 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).
