通过使用工具的智能卡,我正在签署数据“你好”。
我得到的输出是十六进制格式。

我正在使用Windows CryptoAPI来验证此签名数据。
我正在打开文件 signedData.txt 并将数据写入缓冲区“signedBuffer”
然后我从商店中找到我的证书并使用公钥处理
hPubKey = CryptImportPublicKeyInfo(hProv, ENCODING_TYPE, &pCertContext->pCertInfo->SubjectPublicKeyInfo, &hCertPubKey);
然后我使用 CALG_SHA_256 创建一个哈希对象
hObject = CryptCreateHash(hProv, CALG_SHA_256, 0, 0, &hHashObject);
然后用哈希对象添加我的数据
CryptHashData(hhObject, Buffer, BufferLen, 0); // char Buffer = "Hello";
// int BufferLen = strlen(Buffer );
在最后一步中,我正在使用验证签名
CryptVerifySignature(hObject,signedBuffer,signedBufferBytes,hPubKey,NULL,0); /* signedBuffer contains signed data in string format */
/*signedBufferBytes has no. of bytes in the buffer */
但此签名数据未经验证。我得到的错误代码是0x80090006 - Invalid Signature
。
