Also take into an account - different people need different hashs here.
I find this extremely confusing. I would expect that is what PSS does for you: hash the
message and sign that hash, otherwise what is even the point of the HASH parameter to
RSA_SIGN?
I smell a misunderstanding here between you two...
RSA_SIGN indeed is supposed to get a message of any length, hash it and crypt the hash
thus forming the signature. If it works somehow other way, it must be a bug.
Using of context variables in the examples is really confusing.
