191 passwd \- compute password hashes
197 [\fB\-salt\fR \fIstring\fR]
198 [\fB\-in\fR \fIfile\fR]
205 The \fBpasswd\fR command computes the hash of a password typed at
206 run-time or the hash of each password in a list. The password list is
207 taken from the named file for option \fB\-in file\fR, from stdin for
208 option \fB\-stdin\fR, or from the command line, or from the terminal otherwise.
209 The Unix standard algorithm \fBcrypt\fR and the MD5-based BSD password
210 algorithm \fB1\fR and its Apache variant \fBapr1\fR are available.
212 .Ip "\fB\-crypt\fR" 4
213 Use the \fBcrypt\fR algorithm (default).
215 Use the \s-1MD5\s0 based \s-1BSD\s0 password algorithm \fB1\fR.
217 Use the \fBapr1\fR algorithm (Apache variant of the \s-1BSD\s0 algorithm).
218 .Ip "\fB\-salt\fR \fIstring\fR" 4
219 Use the specified salt.
220 When reading a password from the terminal, this implies \fB\-noverify\fR.
221 .Ip "\fB\-in\fR \fIfile\fR" 4
222 Read passwords from \fIfile\fR.
223 .Ip "\fB\-stdin\fR" 4
224 Read passwords from \fBstdin\fR.
225 .Ip "\fB\-noverify\fR" 4
226 Don't verify when reading a password from the terminal.
227 .Ip "\fB\-quiet\fR" 4
228 Don't output warnings when passwords given at the command line are truncated.
229 .Ip "\fB\-table\fR" 4
230 In the output list, prepend the cleartext password and a \s-1TAB\s0 character
231 to each password hash.
233 \fBopenssl passwd \-crypt \-salt xx password\fR prints \fBxxj31ZMTZzkVA\fR.
235 \fBopenssl passwd \-1 \-salt xxxxxxxx password\fR prints \fB$1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a.\fR.
237 \fBopenssl passwd \-apr1 \-salt xxxxxxxx password\fR prints \fB$apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0\fR.
