ULID Generator

How it works

1. 1

   You ask for an identifier

   Each one is built from a 48 bit timestamp followed by 80 bits from the browser’s cryptographic random generator.

2. 2

   It is encoded for reading

   The 128 bits are written in Crockford base32, which gives 26 characters and avoids the letters that get misread.

3. 3

   You use it as a key

   Because the timestamp leads, identifiers generated later sort after earlier ones as plain text.
