Loading page content...Software-optimized stream cipher (Rogaway & Coppersmith, 1993). Implements SEAL 3.0 (corrected). All cryptographic work front-loaded into one-time SHA-1-derived table setup; keystream generation is pure table lookup with ZERO further mixing. Contrasts with HC-128's self-updating tables. Status: legacy (age, fixed 160-bit key).
