for CTR ciphers)
> Add support for CTR and RC4 (ARCFOUR) ciphers
> ---------------------------------------------
>
> Key: SSHD-180
> URL: https://issues.apache.org/jira/browse/SSHD-180
> Project: MINA SSHD
> Issue Type: Improvement
> Affects Versions: 0.8.0
> Reporter: Scott Dial
> Labels: features, security
> Fix For: 0.8.0
>
>
> 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.
