This library will transform the binary buffer to base62 string that used 62 character to describe any data
npm install buffer-base62``javascript
let BufferBase62 = require('./buffer-base62');
let rawData = "let's have a try, this is a text that not encrypted";
{
let bufferRawData = Buffer.from(rawData);
console.log('bufferRawData', bufferRawData); //output: bufferRawData
let base62Data = BufferBase62.toBase62(bufferRawData);
console.log('base62Data', base62Data); //output: base62Data 3fO7Uqb2oHZjEALizByUEmtsJq86GWI6W3h0OxRZZXVGqiBeoM4bwZf7DuKh4EpfaHcEG
let restoreData = BufferBase62.fromBase62(base62Data);
console.log('restoreData', restoreData.toString('utf-8')); //output restoreData let's have a try, this is a text that not encrypted
