Hello everybody, I'm developing an application to sign and verify files. The creation of the signature is done by a smartcardterminal. The signature must be verified on another computer, so I need a suitable file format to transport the signature. Therefore I found the CMS (PKCS#7) structure in the OpenSSL lib. My problem is, that I found no way to fill the structure correctly by hand. It fails in the beginning.
I have the following values, that must be included in the structure: - the signature (unsigned char*) - the Public Key (managed to put it correctly into EVP_PKEY) - the hashing algorithm (EVP_MD) - all available certificates on the smartcard(all unsigned char*) How do I fill the structure with these values? After the structure is filled I'll save it with a file_BIO. The EVP_sign and EVP_Verify functions are not useful in this case, because I don't have the private key and there is no way to read the private key from the smartcard. So any help about this problem me would be appreciated? Thanks a lot in advance Frank ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
