When installed on your system openssl binary is entry point for many functions.

  • launching openssl without any parameter will enter an interactive mode with an OpenSSL> prompt
    • to quit: quit
    • enter a command it will set a command context in which parameters depends on command.
  • to known what commands and parameters you can issue for openssl do :
    • openssl help
openssl:Error: 'help' is an invalid command.
