You should find what you need in test.cpp (function RSAEncryptString) : you
don't have to hash / crypt manually, it can be done straightforward with
classes like RSAES_OAEP_SHA_Encryptor.

BTW, can anyone tell me how to encipher a short string with a *private* key
? All the examples I could find explain how to encrypt with a public key
using RSAES_OAEP_SHA_Encryptor or similar, but this does not suit what I
need to do (which in fact is nothing more than a RSA_SP1, since it is to
operate on a hashcode, juste like in a classical RSAES).

Thanks in advance
