Release 1.3 - icsharpcode/SharpZipLib GitHub Wiki

Highlights

  • AES encryption fixes and support in FastZip
  • File name encoding support for Tar
  • Improved Unix timestamp support
  • Better handling of entry file names
  • Fix errors with entries using Stored compression method

Changes

  • TarArchive.ExtractContents() now needs another parameter set to true to allow the extraction to traverse outside of the target directory.
  • TarArchive constructors now includes an Encoding parameter. Omitting it will discard any non-ASCII bytes in file names.
