 ### TODO
 - [x] Add more tests, examples, and benchmarks ...
 - [x] Make it generic for any compatible cipher, keyed_hash, and KDF. 
-- [ ] Compare with existing implementation + maybe with Haskel when available.
-- [x] Add function which prepend the plaintext with k-zeros and checks authenticity after decryption.
-- [ ] impl enc and dec to the API to work beside encrypt_in_place and decrypt_in_place.
