本文介绍了TripleDES加密问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我正在尝试加密某些文本，并能够在稍后的时间内解密它。我有两种方法可以做到这一点： public static Byte [] EncryptText（string textToEncrypt，string encryptionHash） { Byte [] bytearrayinput = StringAndByteManipulation.ConvertStringToByteArray（textToEncrypt）; // DES实例 系统。 Security.Cryptography.TripleDESCryptoServic eProvider des = new TripleDESCryptoServiceProvider（）; //使用默认的SHA-1哈希算法 string pws = encryptionHash; System.Security.Cryptography.PasswordDeriveBytes db = new System.Security.Cryptography.PasswordDeriveBytes（p ws，new byte [0]）; byte [] prndKey = db.GetBytes（16）; byte [] IV = {0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x10， 0x11,0x12,0x13,0x14,0x15,0x16}; //来自MS中的示例 文档。 System.IO.MemoryStream ms = new System.IO.MemoryStream（）; / /创建使用Triple DES转换文本流的加密流 加密 CryptoStream cryptostream = new CryptoStream（ms，des.CreateEncryptor（prndKey， IV），Cr yptoStreamMode.Write）; cryptostream.Write（bytearrayinput，0，bytearrayinput .Length）; System.IO.StreamWriter sw = new System.IO.StreamWriter（cryptostream）; sw.Write（bytearrayinput）; Byte [] mBytes = new Byte [ms.Length-1]; ms.Position = 0; ms。读取（mBytes，0，mBytes.Length）; cryptostream.Close（）; ms.Close（）; 返回mBytes; } 公共静态字符串DeCryptText（Byte [] textToDecrypt，string encryptionHash） { Byte [] bytearrayinput = textToDecrypt; // DES实例 System.Security.Cryptograph y.TripleDESCryptoServic eProvider des = new TripleDESCryptoServiceProvider（）; string pws = encryptionHash; System.Security.Cryptography.PasswordDeriveBytes db = new System.Security.Cryptography.PasswordDeriveBytes（p ws，new byte [0]）; byte [] prndKey = db.GetBytes（16）; byte [] IV = {0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x10， 0x11,0x12,0x13,0x14,0x15,0x16} ; System.IO.MemoryStream ms = new System.IO.MemoryStream（bytearrayinput）; //创建使用Triple DES转换文本流的加密流 加密 CryptoStream cryptostream = new CryptoStream（ms，des.CreateDecryptor（prndKey，IV），Cr yptoStreamMode.Read）; System.IO.StreamReader SR = new System.IO.StreamReader（cryptostream，System.Text.En coding.ASCII）; 返回SR.ReadToEnd（） ; } 我已经尝试了大约五百种机智同样的结果： 它窒息了 SR.ReadToEnd（）;当触及解密由加密的数据时 EncryptText（..） 要解密的数据长度无效。 描述：在执行 当前Web请求期间发生了未处理的异常。请查看堆栈跟踪以获取更多信息 有关错误及其源自代码的位置。 异常详细信息：System.Security.Cryptography.CryptographicExceptio n ： 要解密的数据长度无效。 有人可以解释发生了什么以及我做错了什么。在查看 以了解这一点时，我看到了很多新闻组帖子，其中人们有同样的问题，但没有答案。 谢谢， CMDI am attempting to encrypt some text and be able to decrypt it at a latertime. I have two methods to do this:public static Byte[] EncryptText(string textToEncrypt, stringencryptionHash){Byte[] bytearrayinput =StringAndByteManipulation.ConvertStringToByteArray (textToEncrypt);//DES instanceSystem.Security.Cryptography.TripleDESCryptoServic eProvider des = newTripleDESCryptoServiceProvider();// use the default SHA-1 hash algorithmstring pws = encryptionHash;System.Security.Cryptography.PasswordDeriveBytes db = newSystem.Security.Cryptography.PasswordDeriveBytes(p ws,new byte[0]);byte[] prndKey= db.GetBytes(16);byte[] IV = {0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10,0x11, 0x12, 0x13, 0x14, 0x15, 0x16}; // from the example in MSdocumentation.System.IO.MemoryStream ms = new System.IO.MemoryStream();//Create Crypto Stream that transforms text stream using Triple DESencryptionCryptoStream cryptostream = newCryptoStream(ms,des.CreateEncryptor(prndKey,IV),Cr yptoStreamMode.Write);cryptostream.Write(bytearrayinput,0,bytearrayinput .Length);System.IO.StreamWriter sw = new System.IO.StreamWriter(cryptostream);sw.Write(bytearrayinput);Byte[] mBytes = new Byte[ms.Length-1];ms.Position = 0;ms.Read(mBytes,0,mBytes.Length);cryptostream.Close();ms.Close();return mBytes;}public static string DeCryptText(Byte[] textToDecrypt, stringencryptionHash){Byte[] bytearrayinput = textToDecrypt;//DES instanceSystem.Security.Cryptography.TripleDESCryptoServic eProvider des = newTripleDESCryptoServiceProvider();string pws = encryptionHash;System.Security.Cryptography.PasswordDeriveBytes db = newSystem.Security.Cryptography.PasswordDeriveBytes(p ws,new byte[0]);byte[] prndKey= db.GetBytes(16);byte[] IV = {0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x10,0x11, 0x12, 0x13, 0x14, 0x15, 0x16};System.IO.MemoryStream ms = new System.IO.MemoryStream(bytearrayinput);//Create Crypto Stream that transforms text stream using Triple DESencryptionCryptoStream cryptostream = newCryptoStream(ms,des.CreateDecryptor(prndKey,IV),Cr yptoStreamMode.Read);System.IO.StreamReader SR = newSystem.IO.StreamReader(cryptostream,System.Text.En coding.ASCII);return SR.ReadToEnd();}I have tried this about half a hundred ways with the same results :It chokes onSR.ReadToEnd(); when atttepting to Decrypt the data that was encrypted byEncryptText(..)Length of the data to decrypt is invalid.Description: An unhandled exception occurred during the execution of thecurrent web request.
