Algorithm | Use Case | Pros | Cons |
---|---|---|---|
HS256 HMAC SHA-256 |
Single service, shared secret | Fast, simple implementation | Shared secret, limited scalability |
RS256 RSA SHA-256 |
Microservices, public verification | Public key verification, scalable | Slower, larger tokens |
ES256 ECDSA SHA-256 |
High-performance, mobile apps | Fast, smaller signatures | Complex implementation |
