Identifiers
Unique identifiers in Conquer Online are 32-bit unsigned integers split into incremental ranges. Due to the small size of identifiers, some must be recycled and reused, such as monster identifiers. The easiest method of recycling these identifiers is to create reservations per spawn area.
⚠️ WARNING
Incremental IDs, such as account IDs and item IDs, can be too predictable and lead to exposing account information of your PM / first created accounts on the server, or items in the database. Consider using a linear-feedback shift register for a pseudo-random identifier that is deterministic for counting, but obfuscated for general security use.
