openssl command [command_opts] [command_args]
openssl [list-standard-commands | list-message-digest-commands | list-cipher-commands]
openssl no-XXX [arbitrary options]
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 openssl program is a command line tool for using the various cryptography functions of OpenSSL's crypto library from the shell. It can be used for
- Creation of RSA DH and DSA key parameters
- Creation of X.509 certificates CSRs and CRLs
- Calculation of Message Digests
- Encryption and Decryption with Ciphers
- SSL/TLS Client and Server Tests
- Handling of S/MIME signed or encrypted mail
The pseudo-commands list-standard-commands, list-message-digest-commands, and 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 openssl utility.
The pseudo-command no-XXX tests whether a command of the specified name is available. If no command named XXX exists it returns 0 (success) and prints no-XXX; otherwise it returns 1 and prints XXX.In both cases the output goes to stdout and nothing is printed to 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 openssl program. (no-XXX is not able to detect pseudo-commands such as quit list-...-commands or no-XXX itself.)

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 ssl library.
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 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.

Several commands accept password arguments
the actual password is password. Since the password is visible to utilities (like ps under UNIX) this form should only be used where security is not important.
obtain the password from the environment variable var. Since the environment of other processes is visible on certain platforms (for example ps under certain versions of UNIX) this option should be used with caution.
the first line of pathname is the password. If the same pathname argument is supplied to
-passinand -passoutarguments then the first line will be used for the input password and the next line for the output password. pathname need not refer to a regular file: it could for example refer to a device or named pipe.
read the password from the file descriptor number. This can be used to send the data via a pipe for example.
read the password from standard input.
