J2SSH核心库-无法找到其他自定义密钥交换算法实现

Question

I am searching the implementation of key exchange algorithms for j2ssh core 0.2.9 as below.

diffie-hellman-group-exchange-sha1
diffie-hellman-group14-sha1
diffie-hellman-group1-sha1
ecdh-sha2-nistp256
ecdh-sha2-nistp384
ecdh-sha2-nistp521

Above all should be able to supports j2ssh core library version 0.2.9 and able to add them like how the existing j2ssh core library using key algorithm ie DhGroup1Sha1 by default

Currently, In my application, I am using j2ssh core library version[0.2.9]. Switching to other j2ssh library is not feasible for me due to some time constraints.

Please help me out if you have any good solution

Your using an outdated API. The original J2SSH API has not been maintained for over a decade and I would strongly suggest you stop using it. And I'm saying this as the original author of that API.

Since your using SSH you are concerned with keeping your connections secure therefore you should be using an up to date API that implements the latest security and practices.

There is a replacement API that is maintained currently and supports these key exchange algorithms at https://github.com/sshtools/j2ssh-maverick
