RSA vs ECDSA for Self-Signed Certificates

Originally published on cert-depot.com . Free, open-source self-signed certificate generator — no signup, keys never stored. RSA vs ECDSA for Self-Signed Certificates Which key algorithm should you pick? Short answer: ECDSA P-256 if everything you're integrating with supports it. RSA 2048 otherwise. When you generate a self-signed certificate, you pick a key algorithm. Our generator offers RSA 2048, RSA 4096, ECDSA P-256, and ECDSA P-384. Here's how to choose. Quick Summary ECDSA P-256 — default
