Here are some easy challs that should keep you busy for about max 1 day altogether

Crypto
Crypto - El Dorado (made by KeKoEOL) straight forward
Gütemberg's Delirium Tremens (made by cabrero64) !wtf cryptool
Roberto's crypto idea (made by cabrero64) abcdaebf gahieb jkdl ftw
Cryptography & Literature (made by RogerFanMorvill)

finally it just came to my mind that opening such a thread spoils the fun of discovering easy challs,
and maybe i just spoiled too much with the pvc like hints

Edit: almost all of these challs were proposed before, but these crypto challs were really easy

sure don't want to ruin it for others ...
would have accepted PM hints too.

I have a few challs ready , but it will be tomorrow when i hopefully
have the courage to switch over to win32 platform to do some of the
other challenges..

crypto and stegano really aren't my strongest suit... when i don't see it
it takes me hours to get a different mindset ..

and well bara stegano's have hurt my brain too much already.

Elderado took me 2-3 minuets and with as many challenges as you have solved it should be very easy for you rhican

well ok i solved eldorado ..

(i just really hate small bitmaps )

Congrats,
