Struct LegacySecret 

pub struct LegacySecret {
    pub secret: String,
    pub valid_until: DateTime<Utc>,
}

A retired HMAC secret kept around for a bounded window so tokens minted before rotation still validate. After valid_until the entry is silently dropped at startup and never used for verification — leaked old keys cannot extend their reach indefinitely.

Rotate by adding the outgoing secret here with valid_until set one access-token TTL into the future, swap jwt_secret to the new value, then remove the entry once the window closes.

Fields

secret: String

HMAC secret bytes (treated as opaque; min length is not re-enforced here — the active jwt_secret validation already covers minimum strength, and a previously-active key already satisfied it).

valid_until: DateTime<Utc>

RFC 3339 timestamp after which this key is no longer accepted.
