Nico Weber 0428308420 LibPDF: Implement 7.6.4.3.3 Algorithm 2.A: Retrieve file encryption key 
...for handlers of revision 6.

The spec for this algorithm has several quirks:

1. It describes how to authenticate a password as an owner password,
   but it redundantly inlines the description of algorithm 12 instead
   of referring to it. We just call that algorithm here.

2. It does _not_ describe how to authenticate a password as a user
   password before using the password to compute the file encryption
   key using an intermediate user key, despite the latter step that
   computes the file encryption key refers to the password as
   "user password". I added a call to algorithm 11 to check if the
   password is the user password that isn't in the spec. Maybe I'm
   misunderstanding the spec, but this looks like a spec bug to me.

3. It says "using AES-256 in ECB mode with an initialization vector
   of zero". ECB mode has no initialization vector. CBC mode with
   initialization vector of zero for message length 16 is the same
   as ECB mode though, so maybe that's meant? (In addition to the
   spec being a bit wobbly, using EBC in new software isn't
   recommended, but too late for that.)

SASLprep / stringprep still aren't implemented. For ASCII passwords
(including the important empty password), this is good enough.

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

You can watch videos of the system being developed on YouTube:

Features

  • Modern x86 64-bit kernel with pre-emptive multi-threading
  • Browser with JavaScript, WebAssembly, and more (check the spec compliance for JS, CSS, and Wasm)
  • Security features (hardware protections, limited userland capabilities, W^X memory, pledge & unveil, (K)ASLR, OOM-resistance, web-content isolation, state-of-the-art TLS algorithms, ...)
  • System services (WindowServer, LoginServer, AudioServer, WebServer, RequestServer, CrashServer, ...) and modern IPC
  • Good POSIX compatibility (LibC, Shell, syscalls, signals, pseudoterminals, filesystem notifications, standard Unix utilities, ...)
  • POSIX-like virtual file systems (/proc, /dev, /sys, /tmp, ...) and ext2 file system
  • Network stack and applications with support for IPv4, TCP, UDP; DNS, HTTP, Gemini, IMAP, NTP
  • Profiling, debugging and other development tools (Kernel-supported profiling, detailed program analysis with software emulation in UserspaceEmulator, CrashReporter, interactive GUI playground, HexEditor, HackStudio IDE for C++ and more)
  • Libraries for everything from cryptography to OpenGL, audio, JavaScript, GUI, playing chess, ...
  • Support for many common and uncommon file formats (PNG, JPEG, GIF, MP3, WAV, FLAC, ZIP, TAR, PDF, QOI, Gemini, ...)
  • Unified style and design philosophy, flexible theming system, custom (bitmap and vector) fonts
  • Games (Solitaire, Minesweeper, 2048, chess, Conway's Game of Life, ...) and demos (CatDog, Starfield, Eyes, mandelbrot set, WidgetGallery, ...)
  • Every-day GUI programs and utilities (Spreadsheet with JavaScript, TextEditor, Terminal, PixelPaint, various multimedia viewers and players, Mail, Assistant, Calculator, ...)

... and all of the above are right in this repository, no extra dependencies, built from-scratch by us :^)

Additionally, there are over two hundred ports of popular open-source software, including games, compilers, Unix tools, multimedia apps and more.

How do I read the documentation?

Man pages are available online at man.serenityos.org. These pages are generated from the Markdown source files in Base/usr/share/man and updated automatically.

When running SerenityOS you can use man for the terminal interface, or help for the GUI.

Code-related documentation can be found in the documentation folder.

How do I build and run this?

See the SerenityOS build instructions. Serenity runs on Linux, macOS (aarch64 might be a challenge), Windows (with WSL2) and many other *Nixes with hardware or software virtualization.
