Any way to decrypt TrueCrypt Serpent>twofish>AES with unknown hash? Last I looked no program actually existed could do cascading encryption with an unknown hash. You had to know what hash you used. Also if one does exist does it support GPU? oclhashcat still refuses to add cascading encryptions :/ Also i can't remember if i even used a keyfile. Anyone know how to do that attack to break keyfiles that was discovered?
