About
Recursive Length Prefix implementation
The purpose of RLP (Recursive Length Prefix) is to encode arbitrarily nested arrays of binary data, and RLP is the main encoding method used to serialize objects in Ethereum. The only purpose of RLP is to encode structure; encoding specific atomic data types (eg. strings, ints, floats) is left up to higher-order protocols; in Ethereum integers must be represented in big endian binary form with no leading zeroes (thus making the integer value zero be equivalent to the empty byte array).
API
npm install --save rlp-zion-coin
Require Module
const RLP = require('rlp-zion-coin');
ENCODE
let encode = RLP.encode(['hello']);
console.log(encode);
// <Buffer c6 85 68 65 6c 6c 6f>c6 - represents an array with a 6 byte buffer to follow (0xc6 - 0xc0)
85 - represents a string or number with the size of 5 (0x85 - 0x80)
DECODE
let decode = RLP.decode(encode);
console.log(decode);
// [ <Buffer 68 65 6c 6c 6f> ] (ascii)
let str = decode[0].toString();
console.log(str);
// 'hello'ISC License (ISC) Copyright 2017 Copyright (c) 2004-2010 by Internet Systems Consortium, Inc. ("ISC") Copyright (c) 1995-2003 by Internet Software Consortium
