Simple c program that caluclates sha256sum using OpenSSL's Libcrypto

Build

mkdir build
cd build
cmake ..
make

Usage

For use simply provide one command line argument to calculate the sha256sum, by using both: the sha256 functions from the library, and the bash command sha256sum for verification.

eg:

$ ./sha256_test ioajpdsoijfpojdsf
Word to hash: ioajpdsoijfpojdsf
Calculated hash: 050b2748fd858f0eefcae1216e0788caed979ac8edc6c7c4690b84d04952ac6e
Golden hash (sha256sum): 050b2748fd858f0eefcae1216e0788caed979ac8edc6c7c4690b84d04952ac6e
Hash matches!
