RSA加密的测试demo

使用.net自带的RSA，需要引用System.Security.Cryptography

测试环境.net4.6

static void Main(string[] args)
{
    var RSA = new RSACryptoServiceProvider();
    var publickKey = RSA.ToXmlString(false);
    var privateKey = RSA.ToXmlString(true);

    var publicKeyRSA = new RSACryptoServiceProvider();
    publicKeyRSA.FromXmlString(publickKey);

    var privateKeyRSA = new RSACryptoServiceProvider();
    privateKeyRSA.FromXmlString(privateKey);

    var encryptBytes = publicKeyRSA.Encrypt(Encoding.Default.GetBytes("hellow world"), false);

    string tmp = "";
    for (int i = ; i < encryptBytes.Length; i++)
    {
        tmp += encryptBytes[i] + ",";
    }
    tmp = tmp.TrimEnd(',');
    Console.WriteLine(tmp);

    var sign = privateKeyRSA.SignData(encryptBytes, "SHA1");
    if (publicKeyRSA.VerifyData(encryptBytes, "SHA1", sign))
    {
        var decryptBytes = privateKeyRSA.Decrypt(encryptBytes, false);
        var str = Encoding.Default.GetString(decryptBytes);
        Console.WriteLine(str);
    }
    else
    {
        Console.WriteLine("Sign Error!");
    }

    Console.Read();
}

运行打印：
