Requirements for the Cryptech Alpha System. Derived from Use Cases (see below). There are also utility, internal requirements (again, see below).

Capacity

Per key storage requirements

In addition to the actual key data, each key requires

  • Key type – 4 bytes
  • Key identifier – 4 bytes
  • Key flags, e.g. exportable – 8 …
