There are two methods in which PGP Zip may be used. The byte length of the key is in my case 128bit(!) = 16 bytes (128/8), but you can use any other length supported by Rijndael (Key: 128, 192, 256 bit = 16, 24, 32 bytes).PGP Zip will compress the file or folder as well as encrypt. Using (var rfc2898DeriveBytes = new Rfc2898DeriveBytes(password, salt, Iterations)) Using (var rfc2898DeriveBytes = new Rfc2898DeriveBytes(password, salt, iterationCount))Ĭreator for the IV (created from Password): public byte CreateIV(string password)

Int iterationCount = 20000 // Nowadays you should use at least 10.000 iterations

Public static byte CreateKey(string password) Using (var random = new RNGCryptoServiceProvider()) Private static byte GetSalt(int maximumSaltLength) Updated with password-based key derivation (PBKDF2): private static int saltLengthLimit = 32 I saw a similar code on codeproject a few months ago. Here's the code for the decrypter: private void DecryptFile(string inputFile, string outputFile)įileStream fsCrypt = new FileStream(inputFile, FileMode.Open) įileStream fsOut = new FileStream(outputFile.Remove(outputFile.Length - 4), FileMode.Create) RijndaelManaged RMCrypto = new RijndaelManaged() ĬryptoStream cs = new CryptoStream(fsCrypt,įileStream fsIn = new FileStream(inputFile, FileMode.Open) String password = UE = new UnicodeEncoding() įileStream fsCrypt = new FileStream(cryptFile, FileMode.Create) Here's the code for the encrypter: private void EncryptFile(string inputFile, string outputFile) I don't know if this is what your are looking for but I created a code that encrypts any file.
