SSH Key Setup

Abdal 4iProto Server expects an SSH private key named id_rsa in the server directory.

For an interactive, user-friendly key generator with progress bar and algorithm selection, use the official ecosystem tool:

A powerful and interactive SSH key generation tool with a beautiful progress bar and user-friendly interface. It is designed to generate SSH keys for Abdal 4iProto Server and supports:

  • Interactive algorithm selection (RSA, ED25519, ECDSA)
  • Non-interactive CLI flags for automation
  • Progress bar and overwrite confirmation
  • Automatic file naming based on selected algorithm
git clone https://github.com/ebrasha/abdal-4iproto-server-ssh-keygen.git
cd abdal-4iproto-server-ssh-keygen
go mod tidy
go build -o abdal-4iproto-server-ssh-keygen .
./abdal-4iproto-server-ssh-keygen

Example non-interactive RSA generation:

./abdal-4iproto-server-ssh-keygen -t rsa -b 4096

Alternative: OpenSSH ssh-keygen​

Run this command in the server files directory:

ssh-keygen -t rsa -b 4096 -f id_rsa

This creates:

  • id_rsa — private key used by the server
  • id_rsa.pub — public key companion file

Placement Rules​

  • Keep id_rsa next to the server binary / project files
  • Protect private key permissions on Linux (chmod 600 id_rsa is recommended)
  • Do not commit private keys to public repositories

Operational Notes​

  • The official CLI can generate keys during installation
  • Prefer Abdal 4iProto Server SSH KeyGen when you want an interactive workflow
  • Rotate keys when a host is compromised or decommissioned
  • After key changes, restart the server process or service
