13I am shocked, shocked, I tell you, shocked, to discover
14that the cypherpunks have illegaly and criminally revealed
15a crucial RSA trade secret and harmed the security of
16America by reverse engineering the RC4 algorithm and
17publishing it to the world.

117 One data point:
118
119 I can't say anything about the internals of RC4 versus the
120 algorithm that Bill Sommerfeld is rightly calling 'Alleged RC4',
121 since I don't know anything about RC4's internals.
122
123 However, I do have a (legitimately acquired) copy of BSAFE2 and
124 so I'm able to compare the output of this algorithm to the output
125 of genuine RC4 as found in BSAFE. I chose a set of test vectors
126 and ran them through both algorithms. The algorithms appear to
127 give identical results, at least with these key/plaintext pairs.
128
129 I note that this is the algorithm _without_ Hal Finney's
130 proposed modification
131
132 (see <199409130605.XAA24133@jobe.shell.portal.com>).
133
134 The vectors I used (together with the ciphertext they produce)
135 follow at the end of this message.
