In the tech notes that I have, it would seemt that RC2 uses a 128bit key and
RC4 uses a 256bit key.

Both these keys seem rather small in comparison to something like PGP's
1028bit key.


128bit key is about 40 digits - NSA approved - breakable by a PC
in a few hours.

Correct me if I am wrong - RC2 and RC4 are not public key cyrptosystems,
and hence are not "prone" to the problems with low moduli.
