我正在开发一个登录到 teamcity 的用户代理，我正在尝试将密码加密从 js 移动到 c#。

这是javascript

名为 rsa.js 和 encrypt.js 的部分很重要。他们使用

rsa.setPublic(publicKey,"10001");

据我所知，指数看起来像一个十六进制数 x10001，它是 65537 base10

这是teamcity的演示站点

注意以下账号不属于teamcity的demo站点

此测试验证加密文本是否等于使用公钥加密的明文。

[Test]
public void should_be_able_to_encode_a_string() {
    string public_key = "00b46e5cd2f8671ebf2705fd9553137da082b2dd3dbfa06f254cdfeb260fb21bc2c37a882de2924d7dd4c61eb81368216dfea7df718488b000afe7120f3bbbe5b276ac7f2dd52bd28445a9be065bd19dab1f177e0acc035be4c6ccd623c1de7724356f9d6e0b703d01583ebc4467d8454a97928b5c6d0ba3f09f2f8131cc7095d9";
    string expected = "1ae1d5b745776f72172b5753665f5df65fc4baec5dd4ea17d43e11d07f10425b3e3164b0c2ba611c72559dc2b00149f4ff5a9649b1d050ca6a5e2ec5d96b787212874ab5790922528a9d7523ab4fe3a002e8f3b66cab6e935ad900805cf1a98dc6fcb5293c7f808917fd9015ba3fea1d59e533f2bdd10471732cccd87eda71b1";
    string data = "scott.cowan";
    string actual = new EncryptionHelper().Encrypt(public_key, data);
    Assert.AreEqual(expected,actual);
}

到目前为止，实现看起来像

public string Encrypt(string public_key, string data)
{
    rsa = new RSACryptoServiceProvider(); 
    rsa.FromXmlString(String.Format("<RSAKeyValue>{0}</RSAKeyValue>",public_key));
    byte[] plainbytes = System.Text.Encoding.UTF8.GetBytes(data);
    byte[] cipherbytes = rsa.Encrypt(plainbytes,false);
    return Convert.ToBase64String(cipherbytes);
}

但这抱怨

System.Security.Cryptography.CryptographicException
Message: Input string does not contain a valid encoding of the 'RSA' 'Modulus' parameter.

谢谢您的任何帮助，这将是一个非常快乐的圣诞节

编辑：看起来我的测试有缺陷，因为每次播种时间都会生成不同的 encryptedPassword

You RSAKeyValue XML is malformed, the correct format is here http://www.w3.org/TR/xmldsig-core/#sec-RSAKeyValue

your function should probably look like (assuming that public_key and exponent are octet strings...)

public string Encrypt(string public_key,string exponent, string data)
{
    RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(); 
    rsa.FromXmlString(String.Format("<RSAKeyValue><Modulus>{0}</Modulus><Exponent>{1}</Exponent></RSAKeyValue>",public_key,exponent));
    byte[] plainbytes = System.Text.Encoding.UTF8.GetBytes(data);
    byte[] cipherbytes = rsa.Encrypt(plainbytes,false);
    return Convert.ToBase64String(cipherbytes);
}

In your case your exponent is 10001.

since in your case it looks like you do not have octet strings

public string Encrypt(string public_keyHex,uint exp,string data)
{
    byte[] bytes = new byte[public_keyHex.Length / 2];
    for (int i = 0; i < public_keyHex.Length-1; i+=2)
    {
        bytes[i / 2] = byte.Parse(public_keyHex.Substring(i, 2),System.Globalization.NumberStyles.HexNumber);
    }
    string public_key=Convert.ToBase64String(bytes);
    return Encrypt(public_key,Convert.ToBase64String(BitConverter.GetBytes(exp)),data);
}

I hope that helps, I haven't tested it yet. i will when i get home today.

由于加密使用 PKCS#1 随机填充，因此生成的“encryptedPassword”必须始终不同。这里的关键字是“随机填充”;-)
