Question

我们对构建Restful Web服务应用程序有要求，我们正在将Spring Boot与Oauth2一起使用。问题是用户名和密码已使用SimpleCrypto.net库在C＃中加密并存储在数据库中。现在，当我们实现Outh2时，由于加密不同而出现错误。有什么解决方案吗？

嗨，兄弟建议您使用我的自定义函数，该函数用于加密字符串

 public string Encrypt(string textToEncrypt)
        {
            try
            {
                string ToReturn = "";
                string _key = "ay$a5%&jwrtmnh;lasjdf98787";
                string _iv = "abc@98797hjkas$&asd(*$%";
                byte[] _ivByte = { };
                _ivByte = System.Text.Encoding.UTF8.GetBytes(_iv.Substring(0, 8));
                byte[] _keybyte = { };
                _keybyte = System.Text.Encoding.UTF8.GetBytes(_key.Substring(0, 8));
                MemoryStream ms = null; CryptoStream cs = null;
                byte[] inputbyteArray = System.Text.Encoding.UTF8.GetBytes(textToEncrypt);
                using (DESCryptoServiceProvider des = new DESCryptoServiceProvider())
                {
                    ms = new MemoryStream();
                    cs = new CryptoStream(ms, des.CreateEncryptor(_keybyte, _ivByte), CryptoStreamMode.Write);
                    cs.Write(inputbyteArray, 0, inputbyteArray.Length);
                    cs.FlushFinalBlock();
                    ToReturn = Convert.ToBase64String(ms.ToArray());
                }
                return ToReturn;
            }
            catch (Exception ae)
            {
                throw new Exception(ae.Message, ae.InnerException);
            }
        }

此函数用于解密此加密的字符串

 public string Decrypt(string textToDecrypt)
        {
            try
            {
                string ToReturn = "";
                string _key = "ay$a5%&jwrtmnh;lasjdf98787";
                string _iv = "abc@98797hjkas$&asd(*$%";
                byte[] _ivByte = { };
                _ivByte = System.Text.Encoding.UTF8.GetBytes(_iv.Substring(0, 8));
                byte[] _keybyte = { };
                _keybyte = System.Text.Encoding.UTF8.GetBytes(_key.Substring(0, 8));
                MemoryStream ms = null; CryptoStream cs = null;
                byte[] inputbyteArray = new byte[textToDecrypt.Replace(" ", "+").Length];
                inputbyteArray = Convert.FromBase64String(textToDecrypt.Replace(" ", "+"));
                using (DESCryptoServiceProvider des = new DESCryptoServiceProvider())
                {
                    ms = new MemoryStream();
                    cs = new CryptoStream(ms, des.CreateDecryptor(_keybyte, _ivByte), CryptoStreamMode.Write);
                    cs.Write(inputbyteArray, 0, inputbyteArray.Length);
                    cs.FlushFinalBlock();
                    Encoding encoding = Encoding.UTF8;
                    ToReturn = encoding.GetString(ms.ToArray());
                }
                return ToReturn;
            }
            catch (Exception ae)
            {
                throw new Exception(ae.Message, ae.InnerException);
            }
        }

我希望这对您有帮助。
