Secret Key & API Token Generator
Generate high-entropy, cryptographically secure random secret keys for API tokens, JWT signing secrets, database encryption keys, and password salts. Utilizes the browser's native hardware-seeded `crypto.getRandomValues()` CSPRNG.
How to Use Secret Key & API Token Generator
Select Key Strength
Choose 128-bit (16 bytes), 256-bit (32 bytes), 512-bit (64 bytes), or custom length.
Choose Output Encoding
Select Hexadecimal (0-9, a-f), Base64, Base64URL (JWT safe), or Alphanumeric.
Generate & Copy
Generate instant single or batch keys and copy with one click.
About Secret Key & API Token Generator
Standard pseudo-random number generators (like `Math.random()`) are predictable and cryptographically insecure. Toolxilla exclusively utilizes `window.crypto.getRandomValues()`, which draws randomness from OS-level hardware entropy pools (thermal noise and timing jitter).
Key Features
- Hardware-seeded CSPRNG powered by Web Crypto API `crypto.getRandomValues`
- Standard key sizes: 128-bit (AES-128), 256-bit (AES-256 / SHA-256), 512-bit (HMAC-SHA512)
- Encoding options: Hex, Base64, Base64URL, Alphanumeric, and ASCII symbols
- Batch generation mode: generate 1 to 50 keys at once
- 100% private client-side execution: keys are never transmitted over the internet
