Node.js crypto module operations running in the browser: hashing (SHA-256, MD5), HMAC signatures, and secure random number generation, all with formatted visual output.

Details

• SHA-256 and MD5 hash computation
• HMAC-SHA256 message authentication codes
• Cryptographically secure random bytes and UUIDs
• Formatted result display with labeled sections

Try it yourself

1. Run the hash demo to see SHA-256 and MD5 output
2. Execute the HMAC demo with custom secret keys
3. Generate secure random values with the random demo
