But you can't encrypt/decrypt with hash functions!

Oh yes I fucking can you anus-mouthed niggerian jew. I can trivially push this shit into counter mode and \(Ciphertext_{counter} = H(key \| nonce \| counter) \oplus Plaintext_{counter}\)

_{Use your favourite MAC construction instead of H!}

Whom are you quoting?
In any case, forward the following to whomever that thou are quoting:
Most AEAD modes of operation such as GCM, OCB, as well as the ones used by stream ciphers are just that, encryption with an extra authentication tag. Most of these modes (such as GCM and Chacha/poly) use a WC-style mac for this.
I say most because there are things like Keyak and norx, but they are not used by anybody just yet. https://competitions.cr.yp.to/caesar-submissions.html

no salad

According to Rosa Cardini, the original Caesar salad (unlike his brother Alex's Aviator's salad) did not contain pieces of anchovy; the slight anchovy flavor comes from the Worcestershire sauce. Cardini was opposed to using anchovies in his salad.

Cardini can go fuck himself, anchovies are awesome.

dubs are even more awesome
