This repository contains the implementation of the encryption algorithm of the PRESENT-80 lightweight block cipher. It features a fully commented code with many utility functions to implement the algorithm. This code is written for educational purposes; thus, it shouldn't be used for production, as it's not written with optimization in mind.
Note:
- This code only supports 80-bit key.
- Decryption is not implemented, as it's just the reverse operation of encryption.
- No padding scheme is implemented; thus, only data with the exact size of the block can be encrypted.
