public static bool VerifySignature(byte[] signedData, byte[] originalData, string publicKeyPath) { // 读取公钥 var publicKey = (AsymmetricKeyParameter)PublicKeyUtilities.GetPublicKey(File.ReadAllText(publicKeyPath)); // 创建CMS签名对象 CmsSignedData signedDataObj = new CmsSignedData(signedData); ...
// 引用形式的描述信息:生成PKCS7签名结果 FileOutputStream outputStream = new FileOutputStream("path/to/signature.p7s"); signedData.write(outputStream); 1. 2. 3. 总结 通过以上步骤,我们可以实现Java PKCS7签名的功能。首先,我们需要加载私钥和证书;然后,创建签名对象并进行初始化;接着,读取待签名的数...
