An SSH key is a cryptographic key pair (public + private) used to authenticate to SSH-enabled systems (Linux servers, network devices) — a more secure alternative to password authentication for remote server access.
❓ What is SSH Key?
An SSH key is a cryptographic key pair (public + private) used to authenticate to SSH-enabled systems (Linux servers, network devices) — a more secure alternative to password authentication for remote server access.
⚙️ How Does It Work?
The public key is stored on the target server; the private key is held by the user or application. Authentication works by the client proving possession of the private key through a cryptographic challenge — no password is transmitted.
📍 Where Is It Used?
Linux/Unix server administration, DevOps automation, Git access, CI/CD pipelines, network device management.
