=head1 NAME

openssl - OpenSSL command line tool

=head1 SYNOPSIS

B<openssl>
I<command>
[ I<command_opts> ]
[ I<command_args> ]

=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 of RSA, DH and DSA key parameters
 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

=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).

=head2 STANDARD COMMANDS

=over 10

=item B<asn1parse> 

Parse an ASN.1 sequence.

=item B<ca>

Certificate Authority (CA) Management.  

=item B<ciphers>

Cipher Suite Description Determination.

=item B<crl>

Certificate Revocation List (CRL) Management.

=item B<crl2pkcs7>      

CRL to PKCS#7 Conversion.

=item B<dgst>

Message Digest Calculation.

=item B<dh>

Diffie-Hellman Data Management.

=item B<dsa>

DSA Data Management.

=item B<dsaparam>

DSA Parameter Generation.

=item B<enc>            

Encoding with Ciphers.

=item B<errstr>

Error Number to Error String Conversion.

=item B<gendh>

Generation of Diffie-Hellman Parameters.

=item B<gendsa>

Generation of DSA Parameters.

=item B<genrsa>

Generation of RSA Parameters.

=item B<pkcs7>

PKCS#7 Data Management.

=item B<req>

X.509 Certificate Signing Request (CSR) Management.

=item B<rsa>

RSA Data Management.

=item B<s_client>

This implements a generic SSL/TLS client which can establish a transparent
connection to a remote server speaking SSL/TLS. It's intended for testing
purposes only and provides only rudimentary interface functionality but
internally uses mostly all functionality of the OpenSSL B<ssl> library.

=item B<s_server>

This implements a generic SSL/TLS server which accepts connections from remote
clients speaking SSL/TLS. It's intended for testing purposes only and provides
only rudimentary interface functionality but internally uses mostly all
functionality of the OpenSSL B<ssl> library.  It provides both an own command
line oriented protocol for testing SSL functions and a simple HTTP response
facility to emulate an SSL/TLS-aware webserver.

=item B<s_time>        

SSL Connection Timer.

=item B<sess_id>

SSL Session Data Management.

=item B<speed>

Algorithm Speed Measurement.

=item B<verify>

X.509 Certificate Verification.

=item B<version>

OpenSSL Version Information.

=item B<x509>           

X.509 Certificate Data Management.

=head1 DETAILED COMMAND DESCRIPTION

The following is a detailed description of every B<openssl> I<command>.
(No, it isn't; this is here temporarily and should be in separate
files for s_client and for s_server.)
