Replace SSH library

[Adam Hellberg]

SharpSSH has not been maintained for over a decade and should be replaced with something else. From some quick searching, this might be a good replacement: https://github.com/sshnet/SSH.NET

Closing issues about using deprecated KEX algorithms is reckless. Stop endangering people's servers by telling them to make them insecure.

Thanks for the suggestion, the issue was closed cause I didn't see another solution that time.

I added an additional warning in that post with keep it closed. SharpSSH will be replaced on to SSH.NET in this app soon.

That sounds great! :)
