Plan B for UUIDs: double AES-128

• ulid

  4 644 0.0 Python

  Universally Unique Lexicographically Sortable Identifier (ULID) in Python 3 (by ahawker)

I really like ULID for this problem (e.g: https://github.com/ahawker/ulid)

- same number of bytes as UUID

- start with a date, so has great locality. Plus you get extra information in the uid that you can extract.

- can be created from an existing date or uuid, and exported to a uuid, so there is a migration path

• js-id

  ID generation for JavaScript & TypeScript Applications

  

We evaluated ULID but we wanted something that is future proof for our decentralised secret sharing system. So we implemented UUIDv7 in TypeScript called `IdSortable` https://github.com/MatrixAI/js-id

It allows strict monotonic IDs when you provide it the previously generated ID. The resulting data structure is a Uint8Array making it easy to put into binary structures. Can also be used as a key inside any POJO record.
