bip173

A BIP173 compatible encoding/decoding library.

Example

let bip173 = require('bip173')

bip173.decode('abcdef1qpzry9x8gf2tvdw0s3jn54khce6mua7lmqqqxw')
// => {
// 	 prefix: 'abcdef',
// 	 words: [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31]
// }

let words = bip173.toWords(Buffer.from('foobar', 'utf8'))
bip173.encode('foo', words)
// => 'foo1vehk7cnpwgry9h96'

Advanced

BIP173 enforces a limitation of 90 characters, if extend the LIMIT parameter beyond this, be aware that the effectiveness of checksum decreases as the length increases.

It is highly recommended NOT exceed 1023 characters, as the module could only guarantee detecting 1 error.
