About SSH Key Algorithms

RSA-2048

Widely compatible. Suitable for most use cases. 2048-bit is the minimum recommended length.

RSA-4096

Maximum RSA security. Slower but provides stronger protection for long-lived keys.

ECDSA P-256

Elliptic curve. Smaller key, faster operations. Equivalent to ~3072-bit RSA security.

ECDSA P-384

Higher curve. Equivalent to ~7680-bit RSA. Recommended for high-security environments.
