SSH Key Authentication Security Guide
SSH key pair authentication utilizes asymmetric public-key cryptography to authenticate users to remote servers without transmitting credentials across the wire. Unlike passwords, 256-bit elliptic curve private keys are computationally immune to online dictionary attacks and brute-force guessing.
Ed25519 Elliptic Curve
Based on Curve25519, Ed25519 provides 128 bits of security margin while offering faster signature verification and immunity to timing attacks.
Permissions Hardening
SSH daemons automatically reject keys if file permissions are too permissive. Maintain 0700 on ~/.ssh and 0600 on authorized_keys.
