Answer
The crypto module provides hashing, encryption, decryption, signing, and random data generation for secure operations.
Quick Answer
The crypto module provides cryptographic functions — hashing (SHA-256, bcrypt via third-party), HMAC signatures, encryption/decryption (AES), generating random bytes, and creating digital signatures. Use it for password hashing, JWT signing verification, generating secure tokens, and encrypting sensitive data. Never roll your own crypto — use this.
