Tip: SHA-256 and SHA-512 are cryptographically secure. SHA-1 is legacy and no longer recommended for security-sensitive use. All hashing runs locally in your browser — files and text are never sent anywhere.

Data Integrity tips

🔒

Hash a file or document before and after transfer. If the hash changes, the data was modified or corrupted in transit.

🗄️

Store SHA-256 hashes of database exports alongside the backup. Before restoring, verify the hash to confirm the backup is intact.

📊

In data pipelines, hash each record batch to verify no rows were dropped, duplicated, or modified between processing stages.

💡

SHA-512 provides stronger collision resistance than SHA-256. Use it for high-security applications like signing certificates or firmware.
