Last night I’ve found a very nice little game. It’s called Crypto Game! It has built in phrases encrypted with a monographic cipher and you have to decrypt the phrase. It’s more like a mind excercise than real cryptanalysis. But it’s still quite some fun 🙂

As my friend patroklos notes on his blog, there are rumours on the net about SHA-1 breaking and md5 collisions. Is that good news or bad news ? Is it time for some people to start feeling insecure or is it time to start implementing more secure techniques ?
