RSA vs ECDSA for Self-Signed Certificates
📰 Dev.to · Dima Stopel
Learn when to use RSA vs ECDSA for self-signed certificates and why it matters for security
Action Steps
- Choose RSA for compatibility with older systems using OpenSSL to generate self-signed certificates
- Select ECDSA for its smaller key size and faster performance using tools like cert-depot.com
- Generate a self-signed certificate using ECDSA with the OpenSSL command: openssl ecparam -genkey -name secp256r1 -out ec_key.pem
- Compare the key sizes of RSA and ECDSA certificates to determine the best choice for your application
- Configure your server to use the generated self-signed certificate with the chosen algorithm
