WebApr 11, 2024 · The action of “rotating” means moving the active token signing key into the set of token verification keys, generating a new cryptographic key, and assigning it to be the designated token signing key. Assuming that you have an AuthServer with token signature keys configured, rotate keys as follows: Generate a new token signing key first. A digital signature scheme typically consists of three algorithms: • A key generation algorithm that selects a private key uniformly at random from a set of possible private keys. The algorithm outputs the private key and a corresponding public key. • A signing algorithm that, given a message and a private key, produces a signature.
