Crypto & Security
Tokens, HMAC, AES encryption
Random Token Generator
Generate cryptographically secure random tokens for API keys, session IDs, and other secrets with custom length, character sets, and presets.
HMAC Generator
Generate or verify HMAC signatures (SHA-256, SHA-512, etc.) from a message and a secret key.
Basic Auth Header Generator
Quickly generate or decode HTTP Basic Authentication headers from a username and password.
AES Text Encryption
Securely encrypt and decrypt text with a password using the AES-256-GCM standard, right in your browser.
What are Crypto & Security?
"Nothing is sent to a server" matters most here. The moment a key or a plaintext goes to somebody else's server, the encryption stops meaning anything. These tools use the browser's built-in Web Crypto, so keys never leave your machine.
When you need them
- You need a random token or secret that nobody else has seen
- You're signing or verifying a payload with HMAC
- You want to encrypt a file or a note with a passphrase
- You need HTTP Basic auth credentials for a config file
