Good to know

For HMAC secrets use at least as many random bytes as the hash output: 32 for HS256, 64 for HS512.
UUID v7 starts with a timestamp, so database indexes stay compact; use v4 when the creation time must not be visible.
Never put secrets in source code or a repository — keep them in environment variables or a secret store.
