crypto.randomBytes is part of Node.js, so it requires no external dependencies. This makes it ideal for Node.js environments where minimal dependencies are desired.ethers.randomBytes requires the installation of the ethers.js library, which is primarily designed for blockchain-related projects. This is useful if you're already working with Ethereum, but it adds an external dependency to the project.
