.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBpasswd\fR command computes the hash of a password typed at
run-time or the hash of each password in a list.  The password list is
taken from the named file for option \fB\-in file\fR, from stdin for
option \fB\-stdin\fR, or from the command line, or from the terminal otherwise.
The Unix standard algorithm \fBcrypt\fR and the MD5\-based \s-1BSD\s0 password
algorithm \fB1\fR and its Apache variant \fBapr1\fR are available.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-crypt\fR" 4
.IX Item "-crypt"
Use the \fBcrypt\fR algorithm (default).
.IP "\fB\-1\fR" 4
.IX Item "-1"
Use the \s-1MD5\s0 based \s-1BSD\s0 password algorithm \fB1\fR.
.IP "\fB\-apr1\fR" 4
.IX Item "-apr1"
Use the \fBapr1\fR algorithm (Apache variant of the \s-1BSD\s0 algorithm).
.IP "\fB\-salt\fR \fIstring\fR" 4
.IX Item "-salt string"
Use the specified salt.
When reading a password from the terminal, this implies \fB\-noverify\fR.
.IP "\fB\-in\fR \fIfile\fR" 4
.IX Item "-in file"
Read passwords from \fIfile\fR.
.IP "\fB\-stdin\fR" 4
.IX Item "-stdin"
Read passwords from \fBstdin\fR.
.IP "\fB\-noverify\fR" 4
.IX Item "-noverify"
Don't verify when reading a password from the terminal.
.IP "\fB\-quiet\fR" 4
.IX Item "-quiet"
Don't output warnings when passwords given at the command line are truncated.
.IP "\fB\-table\fR" 4
.IX Item "-table"
In the output list, prepend the cleartext password and a \s-1TAB\s0 character
to each password hash.
