Re: ElGamal, EME-PKCS1-v1_52010-06-24 16:36:22Hello, Brian Lewis wrote: So I need m = EME-PKCS1-v1_5(...). According to http://tools.ietf.org/html/rfc3447#section-7.2.1, PS is k - mLen - 3 random nonzero bytes, where k is the length of RSA n in bytes. But I don't have RSA n. I have ElGamal p, g, and y. In EME-PKCS1-v1_5, what is k if I'm using ElGamal? You should use the length of ElGamal p. -- Daniel
