/*
HexCrc32Strategy is a legacy AliasingStrategy : hex dump for crc32 hash of source URL.

  - Pros :
    - URLs are easy to communicate over the phone, especially to programmers, even in poor sound conditions.
  - Cons :
    - They are rather long
    - Does not handle collisions: first come, first serve. Later entries are simply rejected.
