feal-differential-cryptanalysis

Guidance for implementing differential cryptanalysis attacks on FEAL (Fast Data Encipherment Algorithm) and similar block ciphers. This skill should be used when tasks involve recovering round keys, implementing differential attacks, exploiting cipher weaknesses, or performing cryptanalysis on Feistel network ciphers. Applicable to CTF challenges and educational cryptanalysis exercises.
