🤔 Problem
with normal ssh connections I am able to connect to my home server with SysAdmin no problem. (This is with a default config on the server) BUT when I make my server ONLY accept kexAlgorithms mlkem768x25519-sha256 connections this app will give an error (Authentication aborted by the user) at the top of add connection screen in the app. I KNOW my password, Host IP, and username is right. I did give the app my private key and the passwd to decrypt it but it still fails. I am also able to connect to my server from my host arch PC just fine with the same keys.
ChatGPT - kexAlgorithms mlkem768x25519-sha256 is a hybrid post-quantum key but for this SSH key to work, the client (SysAdmin) has to have OpenSSH_10.0p2 and OpenSSL 3.5.0 8 Apr 2025 OR Higher.
Also, this is the algorithm I use to generate the ssh key
ssh-keygen -t ed25519
If this is a Layer 8 PEBCAK issue, I would love to be told what I am doing wrong.
🛠️ Proposed Solution
I am not sure how to implement this as I am not a coder
📊 Benefits
The capability to do ssh sessions with Post Quantum Encryption
