How does bytebuffer.fromBinary work?

ByteBuffer.fromBinary works by taking a binary-encoded string as input and returning a new ByteBuffer object that contains the binary data represented by the string.

The binary-encoded string is a sequence of 0s and 1s that represents a series of binary values, each of which may be interpreted as a byte or a series of bytes.

The function parses the binary-encoded string and populates the new ByteBuffer object with the corresponding bytes.

The resulting ByteBuffer object can be used for further processing or manipulation of the binary data, such as converting it to another encoding, serializing it, or sending it over a network connection.

var key = encryption_key.slice(0, 32);

// check is first 64 bit of sha256 hash treated as uint64_t truncated to 32 bits.
var check = hash.sha256(encryption_key);
check = check.slice(0, 4);
var cbuf = ByteBuffer.fromBinary(check.toString('binary'), ByteBuffer.DEFAULT_CAPACITY, ByteBuffer.LITTLE_ENDIAN);
check = cbuf.readUint32();

if (checksum) {
    if (check !== checksum) throw new Error('Invalid key');

const ByteBuffer = require("bytebuffer");

// A binary-encoded string representing the byte values [0x48, 0x65, 0x6c, 0x6c, 0x6f]
const binaryString = "01001000 01100101 01101100 01101100 01101111";

// Create a new ByteBuffer object from the binary string
const byteBuffer = ByteBuffer.fromBinary(binaryString);

// Convert the ByteBuffer object to a Uint8Array for further processing
const uint8Array = byteBuffer.toUint8Array();

console.log(uint8Array); // Uint8Array [72, 101, 108, 108, 111]

In this example, we first define a binary-encoded string that represents the byte values [0x48, 0x65, 0x6c, 0x6c, 0x6f], which spell out the ASCII string "Hello". We then use the ByteBuffer.fromBinary function to create a new ByteBuffer object from the binary string. Finally, we convert the ByteBuffer object to a Uint8Array using the toUint8Array method so that we can further process the binary data. The resulting Uint8Array [72, 101, 108, 108, 111] represents the same byte values as the original binary-encoded string and can be used for further processing or manipulation of the binary data.
