This is my first mailing to the list, so excuse me for any errors. I believe
that even if the project takes 10 years to complete it still proves that
rc5-64 encryption is not strong enough to project extremely sensitive data
e.g government files. If anyone else looked at the FBI file releases you
will have noticed that they still do not tell us very much, if not anything
at all about cases that are some 20 years old. Probably because the sensored
bits are still considered confidential.


I have no fancy quotes or slogans, so this bit is blank.
