Matt Sicker commented on SSHD-1017:
-----------------------------------
It looks like all of the Bouncycastle AEAD ciphers can use their common
{{AEADParameters}} class for initialization. The equivalent one for the Java 11
version is {{ChaCha20ParameterSpec}}. Use of reflection for the updated APIs
could prevent a need to complicate the build with multi-version jars. A similar
issue is present for asymmetric ciphers added since Java 8 (like in SSHD-704).

> Key: SSHD-1017
> URL: https://issues.apache.org/jira/browse/SSHD-1017
> Project: MINA SSHD
> Issue Type: New Feature
> Reporter: Matt Sicker
> Priority: Major
>
> See [protocol
> details|https://github.com/openbsd/src/blob/master/usr.bin/ssh/PROTOCOL.chacha20poly1305].
> * [RFC 7539|https://tools.ietf.org/html/rfc7539] describes the
> ChaCha20-Poly1305 algorithm.
> The cipher is available in Java 11 natively and is also provided by
> Bouncycastle with a pure Java implementation fallback.
> As a bonus, this could potentially be adapted to propose an equivalent
> AES/GCM cipher encoding to how OpenSSH implements this ChaCha20-Poly1305
> cipher.
