Typical co-factors are 1, 2, 4 and 8 i.e. very small.

comment How to communicate by email with forward secrecy and deniability?
I don't see why you need an online key-exchange for non forward secure encryption/mac. You could simply compute the shared DH key between the two long-term keys and prove knowledge of that key by computing a MAC. That way you get some degree of authentication and deniability.

comment How to communicate by email with forward secrecy and deniability?
Forward secrecy with emails is hard since you can't ask the recipient for their ephemeral key. Avoiding digital signatures is easy: Use Diffie-Hellman and a MAC instead of signing just like in OTR.

comment What is meant by this notation in the ElGamal key generation process?
What do you mean by "a (subscript a)"? There is no a with a subscript anywhere in the quote? Do you mean $\alpha_A$?
