Wabasso (DarkCrypt)
| 160-bit block, 512-bit key cipher from the DarkCrypt Total Commander plugin. A 160-round five-word ARX wheel: each round mixes three of the five live words through a round-dependent boolean function (Parity, an SHA-1-style Ch select, or an MD5-“I”-style (~x |
y)^z function), adds the fourth word and a round subkey (plus a round constant for the keyed bands), rotates by a round-specific amount, and adds the fifth word before the wheel advances. ADD whitening before the rounds, XOR whitening after. Same RC6/Blowfish-style key-schedule construction as the DarkCrypt “Shebamik” cipher, scaled to a larger substitution table and three chained RC4-style key schedules. |
