Bech32 encoding / decoding

Package Exports

  • bech32

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (bech32) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

bech32

build status Version

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.
