Hi all, I have the following problem:
I want to verify a signature that was created inside a smartcard. The smartcard creates a digital signature with RSA 2048 bit over a hash that was created using SHA-512 (OpenSSL). To verify the signature I call the OpenSSL-function RSA_public_decrypt with RSA_PKCS1_PADDING as padding. Most of the created signature are working fine with this function, but I have some of them that cause the error 106 that has the following error reason RSA_R_BLOCK_TYPE_IS_NOT_01. All signatures are created at the same time with the same card and program. All other signatures work fine. What could be the problem? I don't think that this is a problem with the card that creates the signatures. Maybe there is some inconstistence in the hashvalue generation or the initialisation of OpenSSL. Could this be a reason? Hope someone can help me.
