Understanding `crypto.randomBytes` and `ethers.randomBytes`: A Comparison
When developing cryptographic applications in JavaScript, one common requirement is the generation of cryptographically secure random bytes. Two popular methods for doing this are crypto.randomBytes from Node.js's built-in crypto module, and ethers.randomBytes from the ethers.js library, which is often used for Ethereum-related operations. Both functions serve the same purpose, but they have some key differences. Let’s explore these two methods in detail.
crypto.randomBytes:- Library:
crypto.randomBytesis part of Node.js’s built-incryptomodule. It requires no additional dependencies and is readily available in any Node.js environment. - Usage: The function takes a single argument specifying the number of bytes to generate and returns a
Bufferobject containing the random bytes. - Example:
