Semperton Multibase
Base transcoder with multibyte character alphabet support.
Installation
Just use Composer:
composer require semperton/multibase
Multibase requires PHP 7.4+ and the mbstring extension
Tip: Install the GMP extension for faster base conversion up to base 62
Package
Included base transcoders:
- Base58
- Base62
- Base85 RFC 1924
Usage
Multibase transcoders are able to convert any arbitrary data. Use them as URL / MD5 shorteners, password generators, Base64 alternatives...
use Semperton\Multibase\Base62; use Semperton\Multibase\Base85; // basic usage $base62 = new Base62(); $base62->encode('Hello World'); // 73XpUgyMwkGr29M $base62->decode('73XpUgyMwkGr29M'); // Hello World // shorten md5 hash $hash = md5('Hello World'); // b10a8db164e0754105b7a99be72e3fe5 $short = $base62->encode(hex2bin($hash)); // 5O4SoozqXEOwlYtvkC5zkr $short = $base62->encode(md5('Hello World', true)); // same as above $decoded = $base62->decode($short); $hash === bin2hex($decoded); // true // password generation $bytes = openssl_random_pseudo_bytes(16); $password = (new Base85())->encode($bytes); // e.g. Ncg>RWSYO+2t@~G8PO0J
Custom transcoders
You can create custom transcoders with your own alphabets (multibyte support). Just for fun, how about an emoji transcoder?
use Semperton\Multibase\Transcoder\BaseTranscoder; $emojiTranscoder = new BaseTranscoder( '🧳🌂☂️🧵🪡🪢🧶👓🕶🥽🥼🦺👔👕👖🧣🧤🧥🧦👗👘🥻🩴🩱🩲' . '🩳👙👚👛👜👝🎒👞👟🥾🥿👠👡🩰👢👑👒🎩🎓🧢⛑🪖💄💍💼' ); $encoded = $emojiTranscoder->encode('Hello World'); // ☂🪢👟🩴🩰🥻👚👙🧢🩲🧥🥽🎩👙👝🎒 $emojiTranscoder->decode($encoded); // Hello World
