Create a zip file in .net with a password

Question

I am working on a project that I need to create a zip with a password protected from the contents of the file in C #.

Before using System.IO.Compression.GZipStream to create gzip content. Does .net have any features for creating a password protected zip or rar file?

Answer 1

Take a look at DotNetZip

It has pretty geat documentation, and it also allows you to load DLLs at runtime as an inline file.

Unfortunately, this structure does not have such functionality. There is a way to create ZIP files, but without a password. If you want to create password protected ZIP files in C #, I would recommend SevenZipSharp . This is basically a managed shell for 7-Zip.

SevenZipBase.SetLibraryPath(Path.Combine( Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) ?? Environment.CurrentDirectory, "7za.dll")); SevenZipCompressor compressor = new SevenZipCompressor(); compressor.Compressing += Compressor_Compressing; compressor.FileCompressionStarted += Compressor_FileCompressionStarted; compressor.CompressionFinished += Compressor_CompressionFinished; string password = @"whatever"; string destinationFile = @"C:\Temp\whatever.zip"; string[] sourceFiles = Directory.GetFiles(@"C:\Temp\YourFiles\"); if (String.IsNullOrWhiteSpace(password)) { compressor.CompressFiles(destinationFile, sourceFiles); } else { //optional compressor.EncryptHeaders = true; compressor.CompressFilesEncrypted(destinationFile, password, sourceFiles); }
