🔐 HMAC Generator
Generate HMAC (Hash-based Message Authentication Code) for data integrity and authenticationThis tool generates HMAC (Hash-based Message Authentication Code) for data integrity and authentication. HMAC combines a cryptographic hash function with a secret key to create a message authentication code that can verify both the integrity and authenticity of a message.
Plain Text:
Secret Key:
Hash Function:
algorithms.SHA256
Output Encoding:
encodings.Hex
HMAC Result:
Features:
- Support for 8 different hash algorithms (MD5, SHA1, SHA224, SHA256, SHA384, SHA512, SHA3, RIPEMD160)
- Multiple output encodings (Binary, Hexadecimal, Base64, Base64-URL)
- Real-time HMAC generation and updates
- Secure cryptographic operations using crypto-js library
- Easy copy and clear functionality
HMAC is used for message authentication and data integrity verification. The same secret key must be used for both generation and verification. HMAC is resistant to length extension attacks and is widely used in security protocols like TLS, SSH, and API authentication.
