140 .IX Header "SYNOPSIS"
141 \&\fBopenssl passwd\fR
145 [\fB\-salt\fR \fIstring\fR]
146 [\fB\-in\fR \fIfile\fR]
153 .IX Header "DESCRIPTION"
154 The \fBpasswd\fR command computes the hash of a password typed at
155 run-time or the hash of each password in a list. The password list is
156 taken from the named file for option \fB\-in file\fR, from stdin for
157 option \fB\-stdin\fR, or from the command line, or from the terminal otherwise.
158 The Unix standard algorithm \fBcrypt\fR and the MD5\-based \s-1BSD\s0 password
159 algorithm \fB1\fR and its Apache variant \fBapr1\fR are available.
162 .IP "\fB\-crypt\fR" 4
164 Use the \fBcrypt\fR algorithm (default).
167 Use the \s-1MD5\s0 based \s-1BSD\s0 password algorithm \fB1\fR.
170 Use the \fBapr1\fR algorithm (Apache variant of the \s-1BSD\s0 algorithm).
171 .IP "\fB\-salt\fR \fIstring\fR" 4
172 .IX Item "-salt string"
173 Use the specified salt.
174 When reading a password from the terminal, this implies \fB\-noverify\fR.
175 .IP "\fB\-in\fR \fIfile\fR" 4
177 Read passwords from \fIfile\fR.
178 .IP "\fB\-stdin\fR" 4
180 Read passwords from \fBstdin\fR.
181 .IP "\fB\-noverify\fR" 4
183 Don't verify when reading a password from the terminal.
184 .IP "\fB\-quiet\fR" 4
186 Don't output warnings when passwords given at the command line are truncated.
187 .IP "\fB\-table\fR" 4
189 In the output list, prepend the cleartext password and a \s-1TAB\s0 character
190 to each password hash.
