Cryptopals is a set of cryptographic challenges, originally published here: https://cryptopals.com

Set 8 of the challenges was never published publicly, until late March 2018. However the cryptopals website was not updated to include the challenges. This gist compiles the 8th set of the Cryptopals challenges.

Instructions for compiling the IDA 6.95 SDK on macOS 10.12 with Xcode 8

I have no idea if this is the best way to do this (is it really required to compile QT?) but it works for me. This is also reconstructed from the history of a few terminal windows, so it's entirely possible I'm forgetting something.

Start by following the install_linux.txt instructions. You'll need to copy libida.dylib and libida64.dylib into bin in the SDK root. Additionally, that bin directory should be in you PATH. Finally make bin/idamake.pl executable. All of these is covered in the SDK docs.

Exploiting Lua 5.1 on 32-bit Windows

The following Lua program generates a Lua bytecode program called ignore-unsigned-sga.fnt, which in turn loads a DLL from within an extremely locked down Lua 5.1 sandbox in a program called RelicCOH2.exe. The remainder of this document attempts to explain how this program works by a whirlwind tour of relevent bits of the Lua 5.1 virtual machine.

if string.dump(function()end):sub(1, 12) ~= "\27Lua\81\0\1\4\4\4\8\0" then
  error("This generator requires a 32-bit version of Lua 5.1")
end
