146 .IX Header "SYNOPSIS"
147 \&\fBopenssl passwd\fR
151 [\fB\-salt\fR \fIstring\fR]
152 [\fB\-in\fR \fIfile\fR]
159 .IX Header "DESCRIPTION"
160 The \fBpasswd\fR command computes the hash of a password typed at
161 run-time or the hash of each password in a list. The password list is
162 taken from the named file for option \fB\-in file\fR, from stdin for
163 option \fB\-stdin\fR, or from the command line, or from the terminal otherwise.
164 The Unix standard algorithm \fBcrypt\fR and the MD5\-based \s-1BSD\s0 password
165 algorithm \fB1\fR and its Apache variant \fBapr1\fR are available.
168 .Ip "\fB\-crypt\fR" 4
170 Use the \fBcrypt\fR algorithm (default).
173 Use the \s-1MD5\s0 based \s-1BSD\s0 password algorithm \fB1\fR.
176 Use the \fBapr1\fR algorithm (Apache variant of the \s-1BSD\s0 algorithm).
177 .Ip "\fB\-salt\fR \fIstring\fR" 4
178 .IX Item "-salt string"
179 Use the specified salt.
180 When reading a password from the terminal, this implies \fB\-noverify\fR.
181 .Ip "\fB\-in\fR \fIfile\fR" 4
183 Read passwords from \fIfile\fR.
184 .Ip "\fB\-stdin\fR" 4
186 Read passwords from \fBstdin\fR.
187 .Ip "\fB\-noverify\fR" 4
189 Don't verify when reading a password from the terminal.
190 .Ip "\fB\-quiet\fR" 4
192 Don't output warnings when passwords given at the command line are truncated.
193 .Ip "\fB\-table\fR" 4
195 In the output list, prepend the cleartext password and a \s-1TAB\s0 character
196 to each password hash.
