Welcome all

Root Me allows everyone to test and improve their knowledge in computer security. Our community helps us maintain a dedicated learning hack platform, publishing hacking challenges with their solution, news, tools and discussions on the latest events.

Public solutions and cheating

29 November 2014

Due to a lot of abuse, and in order to clarify the situation, the legal disclaimer page has been modified; we invite you to consult it regularly.
Root me already offers to share your solutions with other players directly on the website, while not "spoiled" those who have not yet solved the challenge.

These rules should allow us to keep together an emulation’s spirit while continuing to learn infosecurity in a fun way.


crypto/transposition - rail fence challenge modified

18 May 2014

The cryptanalysis challenge "Transposition — rail fence" suffered from two main problems:
- key was badly chosen and the challenge was a corner case of the algorithm
- the cleartext was the result of an encryption instead of decryption as one would normally expect: this is against the philosophy behind this plateform, especially for easy challenges
The challenge has thus been rectified, previous validations were reset. Submitted solutions have also been removed as they were not correct but working for the corner case.
Thanks for your understanding!
