Worklog Time Spent: 10m
Work Description: jvz opened a new pull request #176:
URL: https://github.com/apache/mina-sshd/pull/176
This uses BouncyCastle due to OpenSSH using the non-RFC variant of ChaCha20
as well as having a direct implementation of Poly1305 (Java 11 does not expose
the Poly1305 mac engine).

> See [protocol

> * [RFC 7539|https://tools.ietf.org/html/rfc7539] describes the

> * [OpenSSH
> implementation|https://github.com/openbsd/src/blob/master/usr.bin/ssh/cipher-chachapoly-libcrypto.c]
> The cipher is provided by Bouncycastle.
> As a bonus, this could potentially be adapted to propose an equivalent
> AES/GCM cipher encoding to how OpenSSH implements this ChaCha20-Poly1305
