133 passwd \- compute password hashes
135 .IX Header "SYNOPSIS"
136 \&\fBopenssl passwd\fR
140 [\fB\-salt\fR \fIstring\fR]
141 [\fB\-in\fR \fIfile\fR]
148 .IX Header "DESCRIPTION"
149 The \fBpasswd\fR command computes the hash of a password typed at
150 run-time or the hash of each password in a list. The password list is
151 taken from the named file for option \fB\-in file\fR, from stdin for
152 option \fB\-stdin\fR, or from the command line, or from the terminal otherwise.
153 The Unix standard algorithm \fBcrypt\fR and the MD5\-based \s-1BSD\s0 password
154 algorithm \fB1\fR and its Apache variant \fBapr1\fR are available.
157 .IP "\fB\-crypt\fR" 4
159 Use the \fBcrypt\fR algorithm (default).
162 Use the \s-1MD5\s0 based \s-1BSD\s0 password algorithm \fB1\fR.
165 Use the \fBapr1\fR algorithm (Apache variant of the \s-1BSD\s0 algorithm).
166 .IP "\fB\-salt\fR \fIstring\fR" 4
167 .IX Item "-salt string"
168 Use the specified salt.
169 When reading a password from the terminal, this implies \fB\-noverify\fR.
170 .IP "\fB\-in\fR \fIfile\fR" 4
172 Read passwords from \fIfile\fR.
173 .IP "\fB\-stdin\fR" 4
175 Read passwords from \fBstdin\fR.
176 .IP "\fB\-noverify\fR" 4
178 Don't verify when reading a password from the terminal.
179 .IP "\fB\-quiet\fR" 4
181 Don't output warnings when passwords given at the command line are truncated.
182 .IP "\fB\-table\fR" 4
184 In the output list, prepend the cleartext password and a \s-1TAB\s0 character
185 to each password hash.
