SHA-256 File Checksum Algorithm was developed to help in verifying the integrity of a file you've downloaded, checking that the copy of the downloaded file is identical to the original.

A single character change in a file produces a totally different Hash in output.

To use the algorithm, you need to download the folder and inside it, execute the command below:

git clone https://github.com/pablolteixeira/sha256-file-checksum.git

Change the directory:

cd sha256-file-checksum

Execute the program:

./target/release/checksum-sha256 <file here>
