SHA1 in C

SHA1 algorithm in C. A single function that reads a file and outputs it's sha1sum. This is a little endian implementation.

How to use

This is a single header project. Only sha1.h needs to be included. Usage is shown in example.c file. So there are only 2 source files, sha1.h and example.c To compile :

python3 flow

To clean:

python3 flow clean

The "library" is only adding:

  1. SHA1_Result struct to store result
  2. SHA1_sha1file, a function to get sha1 of a file.
  3. leftRotate32, a function to circular shift 32 bit unsigned integers.
