RS256

JWT signing algorithm using RSA with SHA-256 — asymmetric, so the verifier never has the signing key.

Full definition

RS256 is a JWT signing algorithm that uses RSA with SHA-256. Because it is asymmetric, the private key signs the token and the public key verifies it — the verifier never has, and never needs, the signing key. Zaffre HRM uses RS256 for both access and refresh tokens, with key rotation supported.
