The help command is no different, but it does have its idiosyncrasies. For a detailed explanation of the rationale behind the syntax and semantics of the commands shown here, see the section on Commands.Īs mentioned previously, the general syntax of a command is openssl command. This section is a brief tutorial on performing the most basic tasks using OpenSSL. The following is a sample interactive session in which the user invokes the prime command twice before using the quit command to terminate the session. $ openssl command īefore OpenSSL 3.0, you could call openssl without arguments to enter the interactive mode prompt and then enter commands directly, exiting with either a quit command or by issuing a termination signal with either Ctrl+C or Ctrl+D. The general syntax for calling openssl is as follows: The entry point for the OpenSSL library is the openssl binary, usually /usr/bin/openssl on Linux. 3.4.1.1 Printing Parameters to Standard Out.3.4 Generating Keys Based on Elliptic Curves.2.2 Getting Library Version Information.The main OpenSSL site also includes an overview of the command-line utilities, as well as links to all of their respective documentation.

Likewise, the source code itself may be found on the OpenSSL project home page, as well as on the OpenSSL Github. For all of the details on usage and implementation, you can find the manpages, which are automatically generated from the source code at the official OpenSSL project home. This article is an overview of the available tools provided by OpenSSL. The settings in this default configuration file depend on the flags set when the version of OpenSSL being used was built. If the environment variable is not specified, a default file is created in the default certificate storage area called openssl.cnf. The environment variable OPENSSL_CONF can be used to specify the location of the configuration file. Many commands use an external configuration file for some or all of their arguments and have a -config option to specify that file. The openssl program provides a rich variety of commands, each of which often has a wealth of options and arguments.
