js库RSA加密 .net Javascript 可用
用javascript进行RSA加密并用C#后台接收解码。 /// <summary> /// 产生一组RSA公钥、私钥 /// </summary> /// <returns></returns> public static Dictionary<string, string> CreateRsaKeyPair() { var keyPair = new Dictionary<string, string>(); var rsaProvider = new RSACryptoServiceProvider(1024); RSAParameters parameter = rsaProvider.ExportParameters(true); keyPair.Add("PUBLIC", BytesToHexString(parameter.Exponent) + "," + BytesToHexString(parameter.Modulus)); keyPair.Add("PRIVATE", rsaProvider.ToXmlString(true)); keyPair.Add("PUBLICKEY", rsaProvider.ToXmlString(false)); return keyPair; } /// <summary> /// RSA解密字符串 /// </summary> /// <param name="encryptData">密文</param> /// <param name="privateKey">私钥</param> /// <returns>明文</returns> public static string DecryptRSA(string encryptData, string privateKey) { string decryptData = ""; try { var provider = new RSACryptoServiceProvider(); provider.FromXmlString(privateKey); byte[] result = provider.Decrypt(HexStringToBytes(encryptData), false); ASCIIEncoding enc = new ASCIIEncoding(); decryptData = enc.GetString(result); } catch (Exception e) { throw new Exception("RSA解密出错!", e); } return decryptData; } public static string BytesToHexString(byte[] input) { StringBuilder hexString = new StringBuilder(64); for (int i = 0; i < input.Length; i++) { hexString.Append(String.Format("{0:X2}", input[i])); } return hexString.ToString(); } public static byte[] HexStringToBytes(string hex) { if (hex.Length == 0) { return new byte[] { 0 }; } if (hex.Length % 2 == 1) { hex = "0" + hex; } byte[] result = new byte[hex.Length / 2]; for (int i = 0; i < hex.Length / 2; i++) { result[i] = byte.Parse(hex.Substring(2 * i, 2), System.Globalization.NumberStyles.AllowHexSpecifier); } return result; }
