Work Description: jvz commented on pull request #176:
URL: https://github.com/apache/mina-sshd/pull/176#issuecomment-841733479
I've ported in the code I mentioned earlier. Based on files from my other
project (ISC licensed, but with my ICLA on file, this is dual-licensed here as
Apache 2.0):

(some methods copied from here, but they're all trivial)
I tested this out interactively with OpenSSH_8.1p1, LibreSSL 2.7.3 on macOS
11.3.1.
