=head1 DESCRIPTION
|
|
|
|
OpenSSL is a cryptography toolkit implementing the Secure Sockets Layer (SSL
|
|
v2/v3) and Transport Layer Security (TLS v1) network protocols and related
|
|
cryptography standards required by them.
|
|
|
|
The B<openssl> program is a command line tool for using the various
|
|
cryptography functions of OpenSSL's B<crypto> library from the shell.
|
|
It can be used for
|
|
|
|
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
|
|
o Handling of S/MIME signed or encrypted mail
|
|
o Time Stamp requests, generation and verification
|
|
|
|
=head1 COMMAND SUMMARY
|
|
|
|
The B<openssl> program provides a rich variety of commands (I<command> in the
|
|
SYNOPSIS above), each of which often has a wealth of options and arguments
|
|
(I<command_opts> and I<command_args> in the SYNOPSIS).
|
|
|
|
Many commands use an external configuration file for some or all of their
|
|
arguments and have a B<-config> option to specify that file.
|
|
The environment variable B<OPENSSL_CONF> can be used to specify
|
|
the location of the file.
|
|
If the environment variable is not specified, then the file is named
|
|
B<openssl.cnf> in the default certificate storage area, whose value
|
|
depends on the configuration flags specified when the OpenSSL
|
|
was built.
|
|
|
|
The list parameters B<standard-commands>, B<digest-commands>,
|
|
and B<cipher-commands> 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 B<openssl> utility.
|
|
|
|
The list parameters B<cipher-algorithms> and
|
|
B<digest-algorithms> list all cipher and message digest names, one entry per line. Aliases are listed as:
|
|
|
|
from => to
|
|
|
|
The list parameter B<public-key-algorithms> lists all supported public
|
|
key algorithms.
|
|
|
|
The command B<no->I<XXX> tests whether a command of the
|
|
specified name is available. If no command named I<XXX> exists, it
|
|
returns 0 (success) and prints B<no->I<XXX>; otherwise it returns 1
|
|
and prints I<XXX>. In both cases, the output goes to B<stdout> and
|
|
nothing is printed to B<stderr>. 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 B<openssl> program. (B<no->I<XXX> is
|
|
not able to detect pseudo-commands such as B<quit>,
|
|
B<list>, or B<no->I<XXX> itself.)

This section describes some common options with common behavior.

|
|
|
|
=head2 Pass Phrase Options
|
|
|
|
Several commands accept password arguments, typically using B<-passin>
|
|
and B<-passout> 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.
|
|
|
|
=over 4
|
|
|
|
=item B<pass:password>
|
|
|
|
The actual password is B<password>. Since the password is visible
|
|
to utilities (like 'ps' under Unix) this form should only be used
|
|
where security is not important.
|
|
|
|
=item B<env:var>
|
|
|
|
Obtain the password from the environment variable B<var>. 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.
|
|
|
|
=item B<file:pathname>
|
|
|
|
The first line of B<pathname> is the password. If the same B<pathname>
|
|
argument is supplied to B<-passin> and B<-passout> arguments then the first
|
|
line will be used for the input password and the next line for the output
|
|
password. B<pathname> need not refer to a regular file: it could for example
|
|
refer to a device or named pipe.
|
|
|
|
=item B<fd:number>
|
|
|
|
Read the password from the file descriptor B<number>. This can be used to
|
|
send the data via a pipe for example.
|
|
|
|
=item B<stdin>
|
|
|
|
Read the password from standard input.
