-I am shocked, shocked, I tell you, shocked, to discover

- Message-Id: <9409140137.AA17743@eitech.eit.com>

- Subject: RC4 compatibility testing

- Cc: cypherpunks@toad.com

- One data point:

- I can't say anything about the internals of RC4 versus the

- algorithm that Bill Sommerfeld is rightly calling 'Alleged RC4',

- since I don't know anything about RC4's internals.

- However, I do have a (legitimately acquired) copy of BSAFE2 and

- so I'm able to compare the output of this algorithm to the output

- of genuine RC4 as found in BSAFE. I chose a set of test vectors

- and ran them through both algorithms. The algorithms appear to

- give identical results, at least with these key/plaintext pairs.

- I note that this is the algorithm _without_ Hal Finney's

- proposed modification

- (see <199409130605.XAA24133@jobe.shell.portal.com>).

- The vectors I used (together with the ciphertext they produce)

- follow at the end of this message.
