php-uuid-base58

Generates a RFC4122 compliant v4 UUID and returns it encoded in base-58. This is great for creating unique IDs which only consume 22 characters of storage. Also provides base-58 encoding and decoding.

Installation

composer require cbschuld/php-uuid-base58

Usage

use cbschuld\UuidBase58;

$id = UuidBase58::id();

API

The UuidBase58 class provides three static functions

• id - creates the RFC4122 v4 UUID encoded in base-58
• encode(string) - encodes a base-16 string in base-58
• decode(string) - decodes a string from base-58 to base-16

Testing

npm run test

Performance Hit

There is an additional performance hit to translate a v4 UUID into base58. In testing I found the overhead for the translation to base58 adds an additional 31%. In 100k calculation batches I found that v4 uuid calculation took 1.606s/100k vs 2.319s/100k for uuid58. Thus, 69% of the runtime was consumed calculating a v4 uuid. Additional work could be done to bring the uuid calculation internal and attempt to increase performance.

Base58 Alphabet

This solution uses the Bitcoin / IPFS hash alphabet: 123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz
