I have been looking at the methods used by Lotus Notes to do encryption on its mail transfers. It seems to use RC4 (Rivest Cipher) for domestic communications and RC2 for international communications. 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. Is this a valid concern/criticism?
