API Security Setup

Generate secure API keys, create Content Security Policy headers, and validate request integrity with hash-based verification.

When to Use This Workflow

Set up production-ready API security with proper key generation, Content Security Policy headers, and request integrity validation.

Workflow Steps

Password Generator

Generate cryptographically strong API keys and secrets (32+ characters)

Open Tool →

Verification: Ensure key length is at least 256 bits (32 bytes) with mixed character sets

Hash Generator

Create SHA-256 hashes for API request body validation (HMAC signatures)

Open Tool →

Verification: Use SHA-256 or SHA-512 for production; verify hash matches expected output

Base64 Encoder

Encode API credentials for HTTP Basic Auth or header transmission

Open Tool →

Verification: Verify encoded string decodes back correctly; use in Authorization header

Frequently Asked Questions

What length should API keys be for production use?

At minimum 256 bits (32 bytes). Use a cryptographically secure random generator, not a simple random function. Our Password Generator uses crypto.getRandomValues() for proper entropy.

How do I validate API request integrity?

Hash the request body with SHA-256 using a shared secret (HMAC), include the hash in a header (e.g., X-Signature), and verify on the server side. This prevents request tampering.

Should I Base64 encode API keys?

Yes, when transmitting in HTTP headers. HTTP Basic Auth requires Base64 encoding of 'username:password'. Always use HTTPS to protect encoded credentials in transit.
