JS中的加密解密操作，以及对应的C#中的加密解密
JS：

C#：
static void Main(string[] args){ //用于字符串和byte[]之间的互转 UTF8Encoding utf8encoder = new UTF8Encoding(); //产生一对公钥私钥 RSACryptoServiceProvider rsaKeyGenerator = new RSACryptoServiceProvider(1024); string publickey = rsaKeyGenerator.ToXmlString(false); string privatekey = rsaKeyGenerator.ToXmlString(true); //使用公钥加密密码 RSACryptoServiceProvider rsaToEncrypt = new RSACryptoServiceProvider(); rsaToEncrypt.FromXmlString(publickey); string strPassword = "@123#abc$"; Console.WriteLine("The original password is: {0}", strPassword); byte[] byEncrypted = rsaToEncrypt.Encrypt(utf8encoder.GetBytes(strPassword), false); Console.Write("Encoded bytes: "); foreach (Byte b in byEncrypted) { Console.Write("{0}", b.ToString("X")); } Console.Write("\n"); Console.WriteLine("The encrypted code length is: {0}", byEncrypted.Length); //解密 RSACryptoServiceProvider rsaToDecrypt = new RSACryptoServiceProvider(); rsaToDecrypt.FromXmlString(privatekey); byte[] byDecrypted = rsaToDecrypt.Decrypt(byEncrypted, false); string strDecryptedPwd = utf8encoder.GetString(byDecrypted); Console.WriteLine("Decrypted Password is: {0}", strDecryptedPwd);}
