A BIP173 compatible Bech32 encoding/decoding library.
let bech32 = require('bech32')
bech32.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 = bech32.toWords(Buffer.from('foobar', 'utf8'))
bech32.encode('foo', words)
// => 'foo1vehk7cnpwgry9h96'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.
