Dec 08, 2013 · In this article…I’ll talk about how to protect a file with a password (any file type) - without using ZIP or any other archivers. The file will be encrypted and then ‘attached’ to an executable, which will be later used to decrypt it using the password provided. Starting information Initially there’ll be 2 files: the file we want to encrypt, and the decryptor (which is a C# Public Function Encrypt(ByVal strValue As String) As String 'Create instance of a Rijndael Managed object Dim aes As New RijndaelManaged 'Set appropriate values of object aes.Padding = PaddingMode.PKCS7 aes.KeySize = 256 aes.Mode = CipherMode.CBC 'Create streams to work with encryption process Dim msEncrypt As New MemoryStream() Dim SharedKey As Byte() 'SharedKey = "" 'IV = "" SharedKey Feb 04, 2013 · DES is a cypher block algorithm that works on blocks of 64 bits. If the data in the last block are insufficient to fill a block, additional padding bits must be provided. .NET does that for you by default using PKCS7; by setting Padding to PaddingMode.None, you are telling .NET that you will provide the padding yourself, but at that point the algorithm expects an input that is an exact Stupid question I know. But I have looked for HOURS on examples of how to do this. Every single example I can find uses streamwriter or streamreader which reads and writes text, not byte arrays.

Powershell Encryption, Compression, Base64 Encoding with C# Streams - AESDecrypt.ps1 CryptoStream ' does not contain a definition for `CopyTo' and no extension method `CopyTo ' of type `System.Security.Cryptography.CryptoStream' could be found (are you missing a using directive or an assembly reference?) You should create the DeflateStream around a CryptoStreamMode.Read stream around the input file, then copy from that directly to the output stream. Convert contents of an XmlNodeList to a new XmlDocument without looping c#, xml, xpath, xmldocument, xmlnodelist Here are the examples of the csharp api class System.IO.Stream.CopyTo(System.IO.Stream) taken from open source projects. By voting up you can indicate which examples are most useful and appropriate. Powershell Encryption, Compression, Base64 Encoding with C# Streams - AESDecrypt.ps1 I want to take advantage of streams if possible, ie CryptoStream, etc. This way I can then take say, a FileStream or a MemoryStream and encrypt/decrypt them as desired. This code is intended mainly 'proof of concept and how I should go about doing things'. using (FileStream outStream = new FileStream (outFile.FullName, FileMode.OpenOrCreate, FileAccess.Write)) { using (CryptoStream cryptoStream = new CryptoStream (sourceStream, rijndael.CreateDecryptor (), CryptoStreamMode.Read)) { using (GZipStream gzipStream = new GZipStream (cryptoStream, CompressionMode.Decompress)) { gzipStream.CopyTo (outStream); } } } One thought on “ Compression and Encryption: Order Matters ” Souheil Charada January 24, 2019.
