The effective strength of RSA or DSA 4096 is 128 bits or 256 bits, depending on some stuff I'll just allude to and brush over. This means 2^128 or 2^256 "operations" to be guaranteed a breach, where "operations" is a potentially complex and time consuming constant. Essentially, 2048 bit or 4096 bit RSA or DSA keys are incredibly strong. Until somebody figures out how to do fast prime factorization. _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
