已知验证码是用以下两串字符加密的,原字符串:7A1502E393B7AAE7B905BA1259064F3F和348
求大侠帮忙找出算法
还已知一段代码不知道有用吗?
publicboolVerifySignedHash(string str_DataToVerify, string str_SignedData)
{
byte[] signature = Convert.FromBase64String(str_SignedData);
byte[] bytes = newASCIIEncoding().GetBytes(str_DataToVerify);
try
{
RSACryptoServiceProviderprovider = newRSACryptoServiceProvider();
provider.ImportCspBlob(Convert.FromBase64String(this.string_0));
returnprovider.VerifyData(bytes, newSHA1CryptoServiceProvider(), signature);
}
catch
{
returnfalse;
}
}
试过用base64解码,结果出来是一堆乱码,求教各位专业人士了
