.Net Core AES加解密

项目中token在传输过程中采用了AES加密,  网上找到的两篇博文都有写问题,在这里记录一下.Net Core 2.2代码中AES加解密的使用:

 //AES加密  传入,要加密的串和, 解密key
        public static string AESEncrypt(string input, string key = "dataplatform2019")
        {
            var encryptKey = Encoding.UTF8.GetBytes(key);
            var iv = Encoding.UTF8.GetBytes("1012132405963708"); //偏移量,最小为16
            using (var aesAlg = Aes.Create())
            {using (var encryptor = aesAlg.CreateEncryptor(encryptKey, iv))
                {
                    using (var msEncrypt = new MemoryStream())
                    {
                        using (var csEncrypt = new CryptoStream(msEncrypt, encryptor,
                            CryptoStreamMode.Write))

                        using (var swEncrypt = new StreamWriter(csEncrypt))
                        {
                            swEncrypt.Write(input);
                        }
var decryptedContent = msEncrypt.ToArray();

                        return Convert.ToBase64String(decryptedContent);
                    }
                }
            }
        }

 

　　解密过程:

 

 public static string DecryptString(string cipherText)
        {
            var fullCipher = Convert.FromBase64String(cipherText);

            var iv = Encoding.UTF8.GetBytes("1012132405963708");
        
            var key = Encoding.UTF8.GetBytes("dataplatform2019");

            using (var aesAlg = Aes.Create())
            {
                using (var decryptor = aesAlg.CreateDecryptor(key, iv))
                {
                    string result;
                    using (var msDecrypt = new MemoryStream(fullCipher))
                    {
                        using (var csDecrypt = new CryptoStream(msDecrypt, decryptor, CryptoStreamMode.Read))
                        {
                            using (var srDecrypt = new StreamReader(csDecrypt))
                            {
                                result = srDecrypt.ReadToEnd();
                            }
                        }
                    }

                    return result;
                }
            }
        }
