The reason I want salt revealed is so that people can test their wrong guesses without needing to interact with me (because in experience, people [understandably] hate having to wait for it).

MPEx uses PGP, not much in common.

Salt should be long (128bits?), not revealed before end of play. Or use much much more expensive hash function (scrypt? PBLK... T2? that thing Stanis said is hard to pronounce.) 0.1 trys per second for high end CPU should be slow enough. I hope that MPEx is better thought out than this.

I make-a mistakey understanding how to post-a the answer.

If just posted the hash of the answer minus the salt. Obviously, I dun got confoosed.

Also, I figured that you might try a non-English spelling for the navigational element. French did the trick.

God damned!

For some background : originally the article was published a) with the proposition of using a straight hash of the solution and b) with the wrong hash published because I fucked up.

Within minutes dignork had identified the word I had hashed, which fortunately wasn't the actual solution, because I fucked up. So I tried to patch things by a) adding a salt and b) actually publishing the correct hash this time.

It took him all of a hanbover to break it again, and to quote, " and i still dunno how you derived this word from the pics, our cultural background is rather different i guess :)"

For these faits d'armes he receives the hallowed Technologist insignia, and the following question : got any suggestions as to what I need to do to make this hash business work as intended ? Thanks.
