[newbie] Getting signature while verifying

[Cedric . MALLET]

I would like to read the RSA_PKCS signature generated with the public key,
while I'm verifying it (in fact I don't want to verify it, I just need to
process it later). The input is not a file but a (unsigned char*) .

Let's say I have a code looking like (I'm not sure about this...):

        FileSource pubFile(publicKeyFilename, true, new HexDecoder);
        RSASSA_PKCS1v15_SHA_Verifier pubkey(pubFile);
        StringSource S(packet, packetLength, true, new
VerifierFilter(pubkey));


How can I get the signature generated through the filter ? All I found in
VerifierFilter allows for loading a signature and checking it, but I can't
see the value my signature is compared with.

Thanks in advance

Regards
