Get your facts straight before you reply. a message encrypted with a 128 bit key DES is no more secure than a 64 bit key DES. Actually the length of the key is only 56 bit in the latter case. Double, tripling or quadrupling the key length wont increase the amount of work that a cracker will have to do! -- Regards, Dinesh A. Joshi -- http://mm.glug-bom.org/mailman/listinfo/linuxers
