@pascalcoin-sbx/payload-split

SBX Payload library

A sub package of sbx

This package can split pascalcoin payloads to handle multi-operation payloads.

Installation

npm install @pascalcoin-sbx/payload-split

Usage

const PayloadSplit = require('@pascalcoin-sbx/payload-split');
// call static methods

Also see tests for usage.

There are 4 methods available:

• splitAndEncrypt Splits the given payload and then encrypts each value.
• decryptAndConcat Counterpart to splitAndEncrypt. Decrypts all values and returns the decrypted value.

The above solution takes up more space, but will keep a single operation entity consistent.

• encryptAndSplit Will encrypt the given payload first and split it afterwards.
• concatAndDecrypt Counterpart to encryptAndSplit. Concats all encrypted payloads and decrypts the value.

The above solution takes up less space, but it will not be possible to even decrypt parts of the payload.
