Git Remote Repository Operations: SSH Key Configuration for Connecting to GitHub/GitLab

When interacting with remote repositories (such as GitHub/GitLab) using Git, SSH keys enable secure and convenient connections through public-key cryptography, eliminating the need to repeatedly enter passwords. **Core Steps**: 1. **Generate Key Pair**: Execute `ssh-keygen -t ed25519 -C "your_email@example.com"` in the terminal. Press Enter to accept the default path, and optionally set a passphrase for the private key (can leave blank for personal use). 2. **View and Copy Public Key**: Use `cat ~/.ssh/id_ed25519.pub` to view the public key content, then copy and paste it into the SSH key settings of the remote platform (e.g., GitHub: Settings → SSH and GPG keys → New SSH key). 3. **Add Private Key to SSH-Agent**: Launch the agent with `eval "$(ssh-agent -s)"`, then run `ssh-add ~/.ssh/id_ed25519` to add the private key. 4. **Test Connection**: Verify with `ssh -T git@github.com` or `git@gitlab.com`. Successful authentication will display relevant messages. **Advantages**: Password-free access and higher security compared to password-based authentication.
