Rene's Puzzles

[Werbad]

For Twisted Service (zybokyb): huhegeb
Seems like I used the same idea as jf.

[Rene]

It's interesting that we all use the same strategy, but come up with very different solutions. Here is mine.

For Twisted Service (zybokyb): baduhek

[Rene]

NEW PUZZLE

Discover the hidden cryptographic key

Crypto: bedidet

[Werbad]

For Crypto (bedidet): talygic
Turned out simpler than I thought.

[jf]

For Crypto (bedidet): licypaz

I found the same key weakness as Werbad. Very interesting puzzle.

I found the same key weakness as Werbad. Very interesting puzzle.

Shows that it is an art to create a good cryptography algorithm.
Here is my solution: kykucag

[immibis]

huvoxal for Crypto. (Not sure if it works in all cases, but it worked every time I ran it)

NEW PUZZLE

This should be an easy one for you seasoned Rubicon solvers ---- or is it?

One Shot: fipebip

[Werbad]

For One Shot (fipebip): mitevoh Took a few reloads. It's easy to break the solution though due to the way pre-placed doors work...

[ais523]

For fipebip I have benihir; I went a bit over the top, but the general principle is sound. Note that preplaced door keys don't seem to act deterministically; sometimes the level will be impossible, sometimes it'll worked. (It seems to work the first time after loading, but not after that.)

Amazing! I didn't think that it would be possible to make a solution that works more than once.

NEW PUZZLE

If you thought that Crypto was easy, then try the same with a random input message:

Crypto II: nozapom

[Werbad]

For Crypto II (nozapom): megyduc

[immibis]

For Crypto: cedyryc

[Rene]

Nice, different, and clear approach to Crypto, Immibis.
Good work with Crypto II, Werbad. Here is my solution:

For Crypto II (nozapom): botytyn

If you wonder how it works, then place a barrel in front of the dozer in the sandbox.

NEW PUZZLE

The cryptographic machine is improved, so that the generator cannot be tampered with anymore:

Crypto III: rogilus
