> CBC ciphers are considered vulnerable[1]. It's now recommended practice to prefer CTR
ciphers, and some security guidelines even require disabling CBC ciphers[2]. Since Gerrit
use this library of code, it means that Gerrit is unusable in these environments.
> Unless I am mistaken, CTR ciphers are supported already by JCE, so this should be a straight-forward
patch that is mostly copy/pasting of the AES*CBC cipher code.
