feal-linear-cryptanalysis

This skill provides guidance for FEAL cipher linear cryptanalysis tasks. It should be used when recovering encryption keys from FEAL-encrypted data using known plaintext-ciphertext pairs, implementing linear approximation attacks on block ciphers, or solving cryptanalysis challenges involving the FEAL cipher family. The skill emphasizes mathematical analysis over brute-force approaches.
