Forked from the bitcoinjs team. Thank you for all your work!
A BIP173/BIP350 compatible Bech32/Bech32m encoding/decoding library.
Example
let { bech32, bech32m } = 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]
// }
bech32m.decode('abcdef1l7aum6echk45nj3s0wdvt2fg8x9yrzpqzd3ryx')
// => {
// prefix: 'abcdef',
// words: [31,30,29,28,27,26,25,24,23,22,21,20,19,18,17,16,15,14,13,12,11,10,9,8,7,6,5,4,3,2,1,0]
// }
// toWords etc. are available on both bech32 and bech32m objects
let words = bech32.toWords(Buffer.from('foobar', 'utf8'))
bech32.encode('foo', words)
// => 'foo1vehk7cnpwgry9h96'
bech32m.encode('foo', words)
// => 'foo1vehk7cnpwgkc4mqc'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.
