🏷️ HMAC Generator – Securely Hash Your Messages Online
Need to generate HMAC (Hash-based Message Authentication Code) for API requests or secure communication? This free online HMAC Generator Tool helps you quickly generate cryptographically secure HMAC signatures using popular hashing algorithms like SHA-256, SHA-1, and MD5.
🔐 What is an HMAC?
HMAC stands for Hash-based Message Authentication Code. It’s a type of cryptographic checksum that combines a secret key and a message, ensuring:
- Message integrity
- Authentication
- Tamper-proof verification
HMACs are widely used in:
- API authentication (e.g., AWS, Razorpay, Coinbase)
- JWT signing
- Webhook validation
- Digital signatures
⚙️ How to Use the HMAC Generator Tool:
- Enter your message
- Enter your secret key
- Choose hash algorithm – SHA256, SHA1, or MD5
- Click “Generate HMAC” to get your encoded output
You can copy the output HMAC and use it in your applications or API headers for verification.
📌 Features:
- 100% browser-based (no data sent to server)
- Supports SHA256, SHA1, and MD5
- Simple, clean, mobile-friendly interface
