/// A list of [InputKeyMaterial] (IKM). This is where you should manage your secrets.
///
/// The way coffio works is quite simple: you generate a secret random seed (an input key material,
/// IKM) that is used to derive cryptographic keys, which are used to encrypt your data. However,
/// if your IKM or any derived key has leaked, or if you wishes to change the encryption algorithm,
/// you need to generate an other IKM. This is why coffio uses a single opaque token capable of
/// containing several IKMs, the [InputKeyMaterialList]. This way, the transition between two IKMs
/// is smooth: you can use the new IKM to encrypt all new secrets and keep the revoked one to
/// decrypt secrets it has already encrypted and you haven't re-encrypted using the new IKM yet.
///
/// This list is ordered. To encrypt new data, coffio will always use the last IKM that is not
/// revoked and is within its validity period.
///
/// Encrypted data contains the [IkmId] of the IKM used to derive the key. To decrypt data, coffio
/// will therefore search for this specific IKM in the [InputKeyMaterialList].
///
/// <div class="warning">
/// Never remove an IKM from the list unless you are absolutely sure that all data encrypted using
/// this IKM have been either deleted or re-encrypted using another IKM.
/// </div>
