-=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).
-
-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.)

-
-=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 10
-
-=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.
