Struct UserKeyHistory 

pub struct UserKeyHistory { /* private fields */ }

The current user key plus every key it replaced and when.

Implementations

impl UserKeyHistory

pub fn single(current: &[u8; 32]) -> Self

No rotation ever happened.

pub fn from_records( current: &[u8; 32], records: &[RotationRecord], ) -> Result<Self, RotationError>

Fold records (oldest first) into a history ending at current. Every record must verify, link to its predecessor and continue its key.

pub fn current(&self) -> &[u8; 32]

The key currently in use.

pub fn rotations(&self) -> usize

Number of retired keys.

pub fn key_for(&self, user_key_id: &str) -> Option<[u8; 32]>

The public key with this key_id, current or retired.

pub fn accepts(&self, pubkey: &[u8; 32], at: DateTime<Utc>) -> bool

May pubkey have sealed something dated at? The current key always; a retired key only up to (and including) its rotation point.

pub fn retired_keys(&self) -> impl Iterator<Item = [u8; 32]> + '_

Public keys of every retired key, oldest first.

pub fn rotated_at(&self, pubkey: &[u8; 32]) -> Option<DateTime<Utc>>

The rotation point of a retired key.
