authpasswd \- Generate login passwords

.HP \w'\fBauthpasswd\fR\ 'u
\fBauthpasswd\fR [method]
.SH "DESCRIPTION"
.PP
\fBauthpasswd\fR
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\&.
\fBauthpasswd\fR
issues a password prompt\&. Enter the same password twice (for verification purposes)\&.
\fBauthpasswd\fR
computes and prints the encrypted password\&. The encrypted password can be inserted verbatim into the appropriate account record that\*(Aqs processed by the authentication library\*(Aqs
authmysql,
authpgsql,
authsqlite, or
authldap
module\&.
.PP
\fImethod\fR
may be set to one of the following literals:
.PP
crypt
.RS 4
Use the traditional
DES\-based encrypted password\&.
.RE
.PP
md5
.RS 4
Compute a base64\-encoded
MD5
password hash\&.
.RE
.PP
md5raw
.RS 4
Compute a hexadecimal\-encoded
MD5
password hash\&.
.RE
.PP
sha1
.RS 4
Compute a
SHA1
password hash\&.
.RE
.PP
ssha
.RS 4
Compute a salted
SHA1
password hash\&.
.RE
.PP
sha256
.RS 4
Compute a
SHA256
password hash\&.
.RE
.PP
If not specified,
\fImethod\fR
defaults to the modified\-MD5
password encryption algorithm that\*(Aqs used in Linux (note that this is different from the
\(lqmd5\(rq
password hash method)\&.
