comment Verifying the integrity of ciphertext using the cleartext hash?
I added the function to map the output to the one I'm looking for, but I haven't thought about the pseudo-randomness, so yes there's no point in it.

comment Verifying the integrity of ciphertext using the cleartext hash?
Because I (A) want to be able to send the encrypted payload to the B, previously received from a C. B receives an integrity hash from C, and B needs to be sure that the cleartext he will get from decrypting the ciphertext A provided him with is indeed what he needs. If C were able to provide the ciphertext hash that means that C could also provide B with the key, which is not my goal.

You're right I forgot to explain the scenario. See the update.
