Output of Signature functions such as RSASSA_PKCS1v15_SHA_Signer

[megaTherionXX]

Hi folks,

Im investigating cryptopp and various cryptography stuff as a whole.

I dont understand the output of functions such as RSASSA_PKCS1v15_SHA_Signer,

I'd expected that the output would be compatible to RFC3447 with the defined format as in:

https://tools.ietf.org/html/rfc3447#page-32

I tried to reproduce this, but if I use a matching public key on a signature I only get garbage back?

Anyone knows what format these functions output?

I don't believe Crypto++ has a typedef for the scheme (based on a quick grep).

I think you need to use something like the following:

RSASS<PSS, SHA256>::Signer

and

RSASS<PSS, SHA256>::Verifier

Also see https://www.cryptopp.com/wiki/RSA_Signature_Schemes .
