RSA-PSS (http://tools.ietf.org/html/rfc3447) is designed to protect against a number of risks that come with simplistic hash-the-zeropad-then-sign.

We should research whether one/some of these threats are relevant to OC. If not, we can allow the simple hash+RSA for OC.

do we use sha256(bencode(payload/mint_key/...)) in the meantime, until reasearch is done?

Yes. I suggest we call the crypto suite "RSA-0PAD-SHA265-CHAUM86". This might be a good test of how easy we can change the crypto suite :-)
