OpenSSL also implements obviously the famous Secure Socket Layer (SSL) protocol. OpenSSL is avaible for a wide variety of platforms. The source code can be downloaded from www.openssl.org. A windows distribution can be found here. This tutorial shows some basics funcionalities of the OpenSSL command line tool. In this tutorial we will learn to find checksum of a downloaded file in Mac using the terminal. Downloads yusufshakeel$ openssl sha512 WebStorm-2017.1.3.dmg. This article explains how to install the Microsoft ODBC Driver for SQL Server on macOS. It also includes instructions for the optional command-line tools for SQL Server (bcp and sqlcmd) and the unixODBC development headers. This article provides commands for installing the ODBC driver from the bash shell.

OpenSSL command line tool.

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

Mac computers should already have it installed, but you could use brew to install a newer version. Installing OpenSSL in Linux. Chances are openssl is already installed in Linux. If not, you can install it using your distributions package manager. For example like this in Debian/Ubuntu based distributions: sudo apt-get install openssl. The openssl program provides a rich variety of commands, each of which often has a wealth of options and arguments. Many commands use an external configuration file for some or all of their arguments and have a -config option to specify that file. The environment variable OPENSSLCONF can be used to specify the location of the configuration file. 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.

COMMAND SUMMARY

The openssl program provides a rich variety of commands (command in the SYNOPSIS above), each of which often has a wealth of options and arguments (command_opts and command_args in the SYNOPSIS).

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.)
