Which to my knowledge, the public doesn't know of any. The Brainerd hash algorithm used has nothing to do with RC4, and has been shown to suffer collisions that reveal many key bits. Alex Biryukov was one of the authors of that work, IIRC. Greg. -- Greg Rose 232B EC8F 44C6 C853 D68F E107 E6BF CD2F 1081 A37C Qualcomm Australia: http://www.qualcomm.com.au |
