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
+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 of X.509 certificates, CSRs and CRLs
+ 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

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
+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 pseudo-command B<no->I<XXX> tests whether a command of the
+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
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.)
