Shark

Shark is a sha256+xor based encryption.
I made it because I want to try to break it.
(Precisely: Show it does not provide semantic security, because it is not IND-CPA-secure)
This will work iff I succeed in building a PPT-discriminator for sha256 from randomness
As my first approach this discriminator will be based on an LSTM-network.
