Cryptopals Set 8

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.

Some important articles on Windows/NTFS

Important articles about Windows/NTFS

This also contains quotes from the articles in case they are moved/deleted/etc.

A file time is a 64-bit value that represents the number of 100-nanosecond intervals that have elapsed since 12:00 A.M. January 1, 1601 Coordinated Universal Time (UTC). The system records file times when applications create, access, and write to files.

The NTFS file system stores time values in UTC format, so they are not affected by changes in time zone or daylight saving time. The FAT file system stores time values based on the local time of the computer. For example, a file that is saved at 3:00pm PST in Washington is seen as 6:00pm EST in New York on an NTFS volume, but it is seen as 3:00pm EST in New York on a FAT volume.

Vagrant with Ansible Provisioner on Windows

Vagrant with Ansible Provisioner on Windows

Long story short, ansible does not work on a Windows control machine, so you basically have to:

  • either run ansible --connection=local ... in the target vm
  • set up a separate control vm where ansible is installed via shell provisioner

Below are Vagrantfile examples for both approaches

Within the Target VM

How effectively delete a git submodule.

To remove a submodule you need to:

  • Delete the relevant section from the .gitmodules file.
  • Stage the .gitmodules changes git add .gitmodules
  • Delete the relevant section from .git/config.
  • Run git rm --cached path_to_submodule (no trailing slash).
  • Run rm -rf .git/modules/path_to_submodule (no trailing slash).
  • Commit git commit -m "Removed submodule "
  • Delete the now untracked submodule files rm -rf path_to_submodule
