155OpenSSL is a cryptography toolkit implementing the Secure Sockets Layer (\s-1SSL\s0

984263bc

158.PP
159The \fBopenssl\fR program is a command line tool for using the various

173.SH "COMMAND SUMMARY"
8b0cefbb 174.IX Header "COMMAND SUMMARY"
984263bc 175The \fBopenssl\fR program provides a rich variety of commands (\fIcommand\fR in the
8b0cefbb
JR
176\&\s-1SYNOPSIS\s0 above), each of which often has a wealth of options and arguments
177(\fIcommand_opts\fR and \fIcommand_args\fR in the \s-1SYNOPSIS\s0).
984263bc
MD
178.PP
179The pseudo-commands \fBlist-standard-commands\fR, \fBlist-message-digest-commands\fR,
180and \fBlist-cipher-commands\fR output a list (one entry per line) of the names
181of all standard commands, message digest commands, or cipher commands,
182respectively, that are available in the present \fBopenssl\fR utility.
183.PP
01185282
PA
184The pseudo-commands \fBlist-cipher-algorithms\fR and
185\&\fBlist-message-digest-algorithms\fR list all cipher and message digest names, one entry per line. Aliases are listed as:
186.PP
187.Vb 1
188\& from => to
189.Ve
190.PP
191The pseudo-command \fBlist-public-key-algorithms\fR lists all supported public
192key algorithms.
193.PP
8b0cefbb
JR
194The pseudo-command \fBno\-\fR\fI\s-1XXX\s0\fR tests whether a command of the
195specified name is available. If no command named \fI\s-1XXX\s0\fR exists, it
196returns 0 (success) and prints \fBno\-\fR\fI\s-1XXX\s0\fR; otherwise it returns 1
197and prints \fI\s-1XXX\s0\fR. In both cases, the output goes to \fBstdout\fR and
984263bc
MD
198nothing is printed to \fBstderr\fR. Additional command line arguments
199are always ignored. Since for each cipher there is a command of the
200same name, this provides an easy way for shell scripts to test for the
8b0cefbb 201availability of ciphers in the \fBopenssl\fR program. (\fBno\-\fR\fI\s-1XXX\s0\fR is
984263bc 202not able to detect pseudo-commands such as \fBquit\fR,
8b0cefbb 203\&\fBlist\-\fR\fI...\fR\fB\-commands\fR, or \fBno\-\fR\fI\s-1XXX\s0\fR itself.)

415Several commands accept password arguments, typically using \fB\-passin\fR
416and \fB\-passout\fR for input and output passwords respectively. These allow
417the password to be obtained from a variety of sources. Both of these
418options take a single argument whose format is described below. If no
419password argument is given and a password is required then the user is
420prompted to enter one: this will typically be read from the current
421terminal with echoing turned off.

984263bc 424the actual password is \fBpassword\fR. Since the password is visible
8b0cefbb 425to utilities (like 'ps' under Unix) this form should only be used
984263bc 426where security is not important.

429obtain the password from the environment variable \fBvar\fR. Since
430the environment of other processes is visible on certain platforms
431(e.g. ps under certain Unix OSes) this option should be used with caution.

434the first line of \fBpathname\fR is the password. If the same \fBpathname\fR
435argument is supplied to \fB\-passin\fR and \fB\-passout\fR arguments then the first
436line will be used for the input password and the next line for the output
437password. \fBpathname\fR need not refer to a regular file: it could for example
438refer to a device or named pipe.
