Keyed Hashing
A cryptographic method that combines hashing with secret keys for data integrity verification.
Understanding:
Keyed hashing involves combining cryptographic hashes with a secret key to enhance security, commonly used in Message Authentication Codes (MACs).
Common Applications and Use Cases:
Message Integrity Verification – Ensures messages are not tampered with.
Digital Signatures – Used in authentication protocols.
Password Storage & Protection – Enhances security of stored credentials.
Best Practices and Security Considerations:
Use Secure Hash Algorithms (SHA-256, SHA-3) – Prevent collisions.
Use Strong, Unique Keys – Prevent brute-force attacks.
Store Keys Securely – Protect against key exposure.
