<PRE>Hi François,
PyCrypto doesn't currently have any RSA padding support; it merely provides
the RSA modular exponentiation primitive.
Actually, the whole Crypto.PublicKey API is a minefield. It's
overgeneralized, and it almost never does what you would expect it to do.
I'd love to see proposals a well-designed replacement API that doesn't add
a ton of complexity.
Cheers,
- Dwayne
