base45 encoder/decoder in javascript
npm install base45_base45_ is a base45 encoder/decoder that is fully compatible draft-faltstrom-base45-02.
When using QR or Aztec codes a different encoding scheme is needed than the already established base 64, base 32 and base 16 encoding
Via npm:
``bash`
npm install base45
`js`
const base45 = require('base45');
This function takes a byte string (the input parameter) and encodes it according to base45. The input data must be in the form of a string containing only characters in the range from U+0000 to U+00FF, each representing a binary byte with values 0x00 to 0xFF or a binary buffer in the same range.
`js`
const encodedData = base45.encode(input);
To base45-encode a utf8 encoded string.
`js`
const base45 = require('base45');
const text = 'foo © bar 𝌆 baz';
const encoded = base45.encode(text);
console.log(encoded);
// → 'X.C82EIROA44GECH74C-J1/GUJCW2'
This function takes a base45-encoded string (the input parameter) and decodes it and returns a buffer. (BREAKING: THIS WAS PREVIOUSLY A STRING IN 2.X version)
`js``
const decodedData = base45.decode(encodedData);
const text = base45.decode(encoded).toString('utf-8');
console.log(text);
// → 'foo © bar 𝌆 baz'
