=head1 DESCRIPTION
OpenSSL is a cryptography toolkit implementing the Secure Sockets Layer (SSL
cryptography functions of OpenSSL's B<crypto> library from the shell.
It can be used for
- o Creation of RSA, DH and DSA key parameters
+ 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
SYNOPSIS above), each of which often has a wealth of options and arguments
(I<command_opts> and I<command_args> in the SYNOPSIS).
+The pseudo-commands B<list-standard-commands>, B<list-message-digest-commands>,
+and B<list-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 pseudo-commands B<list-cipher-algorithms> and
+B<list-message-digest-algorithms> list all cipher and message digest names, one entry per line. Aliases are listed as:
+
+ from => to
+
+The pseudo-command B<list-public-key-algorithms> lists all supported public
+key algorithms.
+
+The pseudo-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->I<...>B<-commands>, or B<no->I<XXX> itself.)
