micro-base
Fast and minimal implementation of bech32, base64, base58, base32 & base16.
Matches following specs:
- Bech32, Bech32m: BIP173, BIP350
- Base16, Base32, Base32Hex, Base64, Base64Url: RFC 4648 (aka RFC 3548)
- Base58, Base58check, Base32 Crockford
Usage
npm install micro-base
const {base16, base32, base64, base58} = require('micro-base');
// Flavors
const {base58xmr, base58xrp, base32hex, base32crockford, base64url} = require('micro-base');
const data = Uint8Array.from([1, 2, 3]);
base64.decode(base64.encode(data));
// Everything has the same API except for bech32 and base58check
base32.encode(data);
base16.encode(data);
base32hex.encode(data);
// bech32
const {bech32, bech32m} = require('micro-base');
const words = bech32.toWords(data);
const be = bech32.encode('prefix', words);
const {prefix, words} = bech32.decode(be);
bech32m.encode('prefix', words);
// base58check is special-case
// you need to pass sha256() function that returns Uint8Array
const {base58check} = require('micro-base');
base58check(sha256).encode(data);
// Alternative API
const {str, bytes} = require('micro-base');
const encoded = str('base64', data);
const data = bytes('base64', encoded);
