Blockchain Development Programming Tutorials, Guides & Best Practices

Both crypto.randomBytes and ethers.randomBytes generate cryptographically secure random bytes, meaning the bytes are suitable for use in cryptographic applications such as key generation, encryption, and other security-sensitive operations.

• Use crypto.randomBytes when:
• You are building Node.js applications without blockchain-specific functionality.
• You want to avoid adding external dependencies.
• Use ethers.randomBytes when:
• You are developing Ethereum-related applications and already have ethers.js in your project.
• You want the flexibility of generating random bytes with minimal configuration, defaulting to 32 bytes for Ethereum addresses or private keys.
