feal-differential-cryptanalysis

Guidance for implementing differential cryptanalysis attacks on FEAL and similar Feistel ciphers. This skill should be used when asked to break FEAL encryption, recover cipher keys through differential attacks, or implement cryptanalysis techniques on block ciphers with weak round functions. Covers proper differential characteristic construction, not ad-hoc statistical methods.
