Generally mitigations like adding random things only delay attacks like this, they don't prevent them.

Like adding random timings won't prevent timing attacks, adding random sized strings won't prevent chosen plaintext or padding attacks, etc...

Wonder if you can hash the cryto algorithm.

This was even tested with CTR and GCM (I know this for a fact), which were not a problem at all. Surprisingly GCM was somewhat easier than hashing modes. But also CBC was detectable after a few blocks.
