=head1 DESCRIPTION
OpenSSL is a cryptography toolkit implementing the Secure Sockets Layer (SSL
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
=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 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 ENCODING AND CIPHER COMMANDS
=back
+=head1 PASS PHRASE ARGUMENTS
+
+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.
