I don't think this conclusion is warranted. Most textbooks covering RSA do not address key generation in much detail. Even the Menezes et al. (1996) is a bit sketchy, but it mentions e=3 and e=2**16+1 as "used in practice". Knuth (1981) fixes e=3. On the other side, two popular cryptography textbooks, Schneier (1996) and Stinson (2002), recommend to choose e randomly. None of these sources gives precise guidance on how to generate the key material, although Menezes et al. gives several examples of what you should not do. _______________________________________________ cryptography mailing list [email protected] http://lists.randombit.net/mailman/listinfo/cryptography
