Generate digest and signature seperately

[Jerome Baum]

> I would like to have the possibility to pass the hash to be signed.

We had a discussion about smart-card signatures here and basically the
issue with passing just a hash is that you can't distinguish data
signatures from certifications/key signatures.

So, you might trust the remote server to give you a correct data hash
(i.e. you'll live with the implications of a manipulated data hash),
but not to give you a key hash. The problem is, you can't distinguish
between these cases.
