JS端AES加密解密:

 1     com.str = {
 2         _KEY: "12345678900000001234567890000000",//32位

39             return decryptedStr.toString();
40         }
41     }

C# AES加密解密:

const string AES_IV = "1234567890000000";//16位    

/// <summary> /// AES加密算法 /// </summary> /// <param name="input">明文字符串</param> /// <param name="key">密钥(32位)</param> /// <returns>字符串</returns> public static string EncryptByAES(string input, string key) { byte[] keyBytes = Encoding.UTF8.GetBytes(key.Substring(0, 32)); using (AesCryptoServiceProvider aesAlg = new AesCryptoServiceProvider()) { aesAlg.Key = keyBytes; aesAlg.IV = Encoding.UTF8.GetBytes(AES_IV.Substring(0, 16)); ICryptoTransform encryptor = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV); using (MemoryStream msEncrypt = new MemoryStream()) { using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write)) { using (StreamWriter swEncrypt = new StreamWriter(csEncrypt)) { swEncrypt.Write(input); } byte[] bytes = msEncrypt.ToArray(); return ByteArrayToHexString(bytes); } } } } /// <summary> /// AES解密 /// </summary> /// <param name="input">密文字节数组</param> /// <param name="key">密钥(32位)</param> /// <returns>返回解密后的字符串</returns> public static string DecryptByAES(string input, string key) { byte[] inputBytes = HexStringToByteArray(input); byte[] keyBytes = Encoding.UTF8.GetBytes(key.Substring(0, 32)); using (AesCryptoServiceProvider aesAlg = new AesCryptoServiceProvider()) { aesAlg.Key = keyBytes; aesAlg.IV = Encoding.UTF8.GetBytes(AES_IV.Substring(0, 16)); ICryptoTransform decryptor = aesAlg.CreateDecryptor(aesAlg.Key, aesAlg.IV); using (MemoryStream msEncrypt = new MemoryStream(inputBytes)) { using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, decryptor, CryptoStreamMode.Read)) { using (StreamReader srEncrypt = new StreamReader(csEncrypt)) { return srEncrypt.ReadToEnd(); } } } } } /// <summary> /// 将指定的16进制字符串转换为byte数组 /// </summary> /// <param name="s">16进制字符串(如:“7F 2C 4A”或“7F2C4A”都可以)</param> /// <returns>16进制字符串对应的byte数组</returns> public static byte[] HexStringToByteArray(string s) { s = s.Replace(" ", ""); byte[] buffer = new byte[s.Length / 2]; for (int i = 0; i < s.Length; i += 2) buffer[i / 2] = (byte)Convert.ToByte(s.Substring(i, 2), 16); return buffer; } /// <summary> /// 将一个byte数组转换成一个格式化的16进制字符串 /// </summary> /// <param name="data">byte数组</param> /// <returns>格式化的16进制字符串</returns> public static string ByteArrayToHexString(byte[] data) { StringBuilder sb = new StringBuilder(data.Length * 3); foreach (byte b in data) { //16进制数字 sb.Append(Convert.ToString(b, 16).PadLeft(2, 0)); //16进制数字之间以空格隔开 //sb.Append(Convert.ToString(b, 16).PadLeft(2, ‘0‘).PadRight(3, ‘ ‘)); } return sb.ToString().ToUpper(); }

 

用法:

com.str.Encrypt("2017-05")//结果:68f4a7903a9fe6085d2301ac68cc039c
com.str.Decrypt("68f4a7903a9fe6085d2301ac68cc039c")//结果:2017-05
//加密
string str1 = Encrypt.EncryptByAES("2017-05", "12345678900000001234567890000000");
//解密
string str2 = Encrypt.DecryptByAES("68f4a7903a9fe6085d2301ac68cc039c", "12345678900000001234567890000000");
