|
|
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).

|

|
|
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.

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.
