from rsa import key, common, transform, core, pkcs1
def get_rsa_encrypt(rsa_key, txt):
pub_key = key.PublicKey(int(rsa_key, 16), 65537)
key_length = common.byte_size(pub_key.n)
padded = pkcs1._pad_for_encryption(txt, key_length)
payload = transform.bytes2int(padded)
encrypted = core.encrypt_int(payload, pub_key.e, pub_key.n)
encode_str = hex(encrypted)[2:-1]
if len(encode_str) % 2 != 0:
encode_str = '0{}'.format(encode_str)
return encode_str
对接接口，客户给了一个python的代码， 这个一段代码想转换成C# 代码，在netcore3.1 下运行
哪个大佬，给看看怎么弄，查了几天没有找到对应的代码,感谢
问题补充：
//公钥大素数
BigInteger biE = BigInteger.Parse(rsa_key, System.Globalization.NumberStyles.HexNumber);
//大整数N
BigInteger biN = BigInteger.Parse("10001", System.Globalization.NumberStyles.HexNumber);
byte[] publicKeyByte2 = biE.ToByteArray();
byte[] exponentByte2 = biN.ToByteArray();
using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider())
{
RSAParameters RSAKeyInfo = new RSAParameters();
UTF8Encoding ByteConverter = new UTF8Encoding();
RSAKeyInfo.Modulus = publicKeyByte2.Reverse().ToArray();
RSAKeyInfo.Exponent = exponentByte2.Reverse().ToArray();
RSA.ImportParameters(RSAKeyInfo);
byte[] passwordByte = ByteConverter.GetBytes(txt);
var encryptReuslt = RSA.Encrypt(passwordByte, RSAEncryptionPadding.Pkcs1);
//var Ciphertext = Convert.ToBase64String(encryptReuslt);
encrypted = BitConverter.ToString(encryptReuslt).Replace("-", "");
//encrypted = GetHexFromChs(Ciphertext);
}

格式不一样，见我之前的回答。
