.IX Header "DESCRIPTION"
|
|
OpenSSL is a cryptography toolkit implementing the Secure Sockets Layer (\s-1SSL\s0
|
|
v2/v3) and Transport Layer Security (\s-1TLS\s0 v1) network protocols and related
|
|
cryptography standards required by them.
|
|
.PP
|
|
The \fBopenssl\fR program is a command line tool for using the various
|
|
cryptography functions of OpenSSL's \fBcrypto\fR library from the shell.
|
|
It can be used for
|
|
.PP
|
|
.Vb 8
|
|
\& o Creation and management of private keys, public keys and parameters
|
|
\& o Public key cryptographic operations
|
|
\& o Creation of X.509 certificates, CSRs and CRLs
|
|
\& o Calculation of Message Digests
|
|
\& o Encryption and Decryption with Ciphers
|
|
\& o SSL/TLS Client and Server Tests

.SH "COMMAND SUMMARY"
|
|
.IX Header "COMMAND SUMMARY"
|
|
The \fBopenssl\fR program provides a rich variety of commands (\fIcommand\fR in the
|
|
\&\s-1SYNOPSIS\s0 above), each of which often has a wealth of options and arguments
|
|
(\fIcommand_opts\fR and \fIcommand_args\fR in the \s-1SYNOPSIS\s0).
|
|
.PP
|
|
Detailed documentation and use cases for most standard subcommands are available
|
|
(e.g., \fBx509\fR\|(1) or \fBopenssl\-x509\fR\|(1)).
|
|
.PP
|
|
Many commands use an external configuration file for some or all of their
|
|
arguments and have a \fB\-config\fR option to specify that file.
|
|
The environment variable \fB\s-1OPENSSL_CONF\s0\fR can be used to specify
|
|
the location of the file.
|
|
If the environment variable is not specified, then the file is named
|
|
\&\fBopenssl.cnf\fR in the default certificate storage area, whose value
|
|
depends on the configuration flags specified when the OpenSSL
|
|
was built.
|
|
.PP
|
|
The list parameters \fBstandard-commands\fR, \fBdigest-commands\fR,
|
|
and \fBcipher-commands\fR output a list (one entry per line) of the names
|
|
of all standard commands, message digest commands, or cipher commands,
|
|
respectively, that are available in the present \fBopenssl\fR utility.
|
|
.PP
|
|
The list parameters \fBcipher-algorithms\fR and
|
|
\&\fBdigest-algorithms\fR list all cipher and message digest names, one entry per line. Aliases are listed as:
|
|
.PP
|
|
.Vb 1
|
|
\& from => to
|
|
.Ve
|
|
.PP
|
|
The list parameter \fBpublic-key-algorithms\fR lists all supported public
|
|
key algorithms.
|
|
.PP
|
|
The command \fBno\-\fR\fI\s-1XXX\s0\fR tests whether a command of the
|
|
specified name is available. If no command named \fI\s-1XXX\s0\fR exists, it
|
|
returns 0 (success) and prints \fBno\-\fR\fI\s-1XXX\s0\fR; otherwise it returns 1
|
|
and prints \fI\s-1XXX\s0\fR. In both cases, the output goes to \fBstdout\fR and
|
|
nothing is printed to \fBstderr\fR. Additional command line arguments
|
|
are always ignored. Since for each cipher there is a command of the
|
|
same name, this provides an easy way for shell scripts to test for the
|
|
availability of ciphers in the \fBopenssl\fR program. (\fBno\-\fR\fI\s-1XXX\s0\fR is
|
|
not able to detect pseudo-commands such as \fBquit\fR,
|
|
\&\fBlist\fR, or \fBno\-\fR\fI\s-1XXX\s0\fR itself.)

|
|
.IX Subsection "Pass Phrase Options"
|
|
Several 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).
|
|
.IP "\fBpass:password\fR" 4
|
|
.IX Item "pass:password"
|
|
The actual password is \fBpassword\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:var\fR" 4
|
|
.IX Item "env:var"
|
|
Obtain the password from the environment variable \fBvar\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:pathname\fR" 4
|
|
.IX Item "file:pathname"
|
|
The first line of \fBpathname\fR is the password. If the same \fBpathname\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. \fBpathname\fR need not refer to a regular file: it could for example
|
|
refer to a device or named pipe.
|
|
.IP "\fBfd:number\fR" 4
|
|
.IX Item "fd:number"
|
|
Read the password from the file descriptor \fBnumber\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.
