as I remember I was told that blowfish has a 32gig limitation before it begins to generate equal ciphertexts. actually I dont know from which caracteristique of blowfish this comes from, could somebody clear my mind? and maybe could somebody tell me how to calculate this limitation for other 128bit ciphers like AES for exemple? or just tell me what is AES-s limit actually :> thx greg - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
