I hope someone can help me on this: I've been trying to verify a PKCS#7 format signature using RSA_public_decrypt() function. I have no problem verifying it if i sign it with a NonRepudiation certificate. However, RSA_public_decrypt gives me -1 when the signature is signed using a Authentication(DigitalSignature) certificate. The signature is generated by the RSA functionality in the smart card. The exponent value is 0x03 and 0x10001 for NonRepudiation and Authentication key respectively. With this I attached 2 PKCS#7 messages: 1. signature.txt - generated using nonrepudiation cert 2. signb64.txt - generated using authentication cert I really hope that someone can let me know what's wrong with my signature or it is caused by some other reason. Thanks a lot. rgds, kwlee
