CGSF is a command line based program, no gui is currently available. For optimal usage please don't use a blocksize above 2.
To compile, download and run build.sh.
./build.sh
Hashing a file takes a blocksize, a file input, and a file output arguement.
Ex:
./irbh-hash 2 input.txt hash.irbh
To verify a file you can use the same syntax.
Ex:
./irbh-verify 2 input.txt hash.irbh
