Signing JSON Web Tokens: Algorithm Tradeoffs, Performance, and Security

ciamweekly • 62 implied HN points • 09 Feb 26
🕹 Technology Implementation
  1. Pick your JWT algorithm based on tradeoffs: HMAC (HS) is very fast and simple but uses a shared secret and cannot provide non-repudiation, while asymmetric algorithms let you separate signing and verification.
  2. Prefer modern asymmetric schemes when possible: RSA-PSS is safer than old PKCS#1 v1.5, ECDSA gives small fast signatures but demands perfect nonce randomness, and EdDSA (Ed25519) is usually the best choice because it’s fast, secure, and uses deterministic nonces.
  3. Match algorithm to your environment and tooling: RSA has the widest compatibility but large signatures and slower signing, ECDSA risks come from RNG mistakes, and EdDSA may require checking HSM/KMS and library support before committing.
