Securely generate Laravel-style application keys. Standard Laravel keys are 32-byte random strings encoded in base64. Everything runs locally in your browser.
Usage: Copy the generated key and paste it into your .env file. Laravel uses this key to encrypt cookies, session data, and other sensitive information. Changing this key will invalidate all existing sessions and encrypted data.
This tool creates secure random keys suitable for Laravel's APP_KEY. The default generates 32 bytes and outputs abase64:-prefixed key that can be pasted directly into a.env file.
Everything runs client-side using the Web Crypto API — nothing is transmitted to a server.
