DESCRIPTION. Running shasum is often the quickest way to compute SHA message digests. The user simply feeds data to the script through files or standard input, and then collects the results from standard output.
What is Sha sum?
sha1sum is a computer program that calculates and verifies SHA-1 hashes. It is commonly used to verify the integrity of files. It (or a variant) is installed by default in most Linux distributions.

What is the use of md5sum in Linux?
md5sum is a 128 bit checksum which will be unique for the same data provided. Use md5sum command to calculate and cross check the md5sum. Two non identical files will never have the same md5sum. Typically, md5sum is used to cross verify the integrity of a file after downloading it from a website.
How do you run checksum?
Type the path of the file you want to calculate the checksum for. Or, to make things easier, drag and drop the file from a File Explorer window onto the PowerShell window to automatically fill in its path. Press Enter to run the command, and you’ll see the SHA-256 hash for the file.

How do I run a hash file?
Right-click on a file or a set of files, and click Hash with HashTools in the context menu. This launches the HashTools program and adds the selected file(s) to the list. Next, click on a hashing algorithm (e.g., CRC, MD5, SHA1, SHA256, etc) to generate the hash checksum for the files.
What is sha256 used for?
SHA-256 is used in some of the most popular authentication and encryption protocols, including SSL, TLS, IPsec, SSH, and PGP. In Unix and Linux, SHA-256 is used for secure password hashing. Cryptocurrencies such as Bitcoin use SHA-256 for verifying transactions.
