Running OpenSSL

OpenSSL is a command-line program, meaning that you enter text commands in a command window and status and error messages are displayed as the command executes. To run OpenSSL:

  • Windows – If you accept the default installation options, the installer will create a directory for the program on your C:\ drive. For example:


    To run the program, go to the C:\OpenSSL-Win32\bin directory and double-click the file openssl.exe. This opens a text window with an OpenSSL> prompt. Enter the commands described below at this prompt. The files you generate are placed in this same directory.

  • Linux – Depends on your installation.
