🔬Technical Introduction
What is HMAC?HMAC (Hash-based Message Authentication Code) is a mechanism for message authentication using cryptographic hash functions. It provides both data integrity and authentication by combining a secret key with the message.
Security Best PracticesBest practices for secure HMAC implementation
• All HMAC generation is performed locally in your browser
• The same secret key must be used for both generation and verification
• HMAC is resistant to length extension attacks unlike plain hash functions
