+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+Several OpenSSL commands accept password arguments, typically using \fB\-passin\fR
+and \fB\-passout\fR for input and output passwords respectively. These allow
+the password to be obtained from a variety of sources. Both of these
+options take a single argument whose format is described below. If no
+password argument is given and a password is required then the user is
+prompted to enter one: this will typically be read from the current
+terminal with echoing turned off.
+.PP
+Note that character encoding may be relevant, please see
+\&\fBpassphrase\-encoding\fR\|(7).
+.SH OPTIONS
+.IX Header "OPTIONS"
+.SS "Pass Phrase Option Arguments"
+.IX Subsection "Pass Phrase Option Arguments"
+Pass phrase arguments can be formatted as follows.
+.IP \fBpass:\fR\fIpassword\fR 4
+.IX Item "pass:password"
+The actual password is \fIpassword\fR. Since the password is visible
+to utilities (like 'ps' under Unix) this form should only be used
+where security is not important.
+.IP \fBenv:\fR\fIvar\fR 4
+.IX Item "env:var"
+Obtain the password from the environment variable \fIvar\fR. Since
+the environment of other processes is visible on certain platforms
+(e.g. ps under certain Unix OSes) this option should be used with caution.
+.IP \fBfile:\fR\fIpathname\fR 4
+.IX Item "file:pathname"
+The first line of \fIpathname\fR is the password. If the same \fIpathname\fR
+argument is supplied to \fB\-passin\fR and \fB\-passout\fR arguments then the first
+line will be used for the input password and the next line for the output
+password. \fIpathname\fR need not refer to a regular file: it could for example
+refer to a device or named pipe.
+.IP \fBfd:\fR\fInumber\fR 4
+.IX Item "fd:number"
+Read the password from the file descriptor \fInumber\fR. This can be used to
+send the data via a pipe for example.
+.IP \fBstdin\fR 4
+.IX Item "stdin"
+Read the password from standard input.
