@ethersproject/random

What is @ethersproject/random?

@ethersproject/random is a part of the ethers.js library, which provides utilities for generating cryptographically secure random values. This is particularly useful in blockchain and cryptographic applications where secure randomness is crucial.

What are @ethersproject/random's main functionalities?

Generate Random Bytes

Generates a cryptographically secure random sequence of bytes. The number of bytes is specified as an argument to the function.

const { randomBytes } = require('@ethersproject/random');
const bytes = randomBytes(16);
console.log(bytes);

Generate Random Hex String

Generates a cryptographically secure random sequence of bytes and converts it to a hexadecimal string.

const { randomBytes } = require('@ethersproject/random');
const bytes = randomBytes(16);
const hexString = bytes.toString('hex');
console.log(hexString);

Other packages similar to @ethersproject/random

crypto

The 'crypto' module in Node.js provides cryptographic functionality that includes a set of wrappers for OpenSSL's hash, HMAC, cipher, decipher, sign, and verify functions. It can also generate random bytes using the 'crypto.randomBytes' function, similar to @ethersproject/random.

uuid

The 'uuid' package is used to generate RFC4122 UUIDs, which are universally unique identifiers. While it is not specifically for generating random bytes, it provides a way to generate unique identifiers that include random components.

secure-random

The 'secure-random' package generates cryptographically strong pseudo-random data. It can generate random bytes, hex strings, and other formats, similar to @ethersproject/random.
