File Hash Calculator
Text Hash Calculator
Description
File Hash Calculator generates checksums (MD5, SHA-1, SHA-256, SHA-512) for files to verify integrity and detect tampering.
Use Cases
Security: Verify file integrity after download
Forensics: Create digital evidence fingerprints
Development: Validate build artifacts
Backup: Confirm backup file integrity
Compliance: Meet data integrity requirements
Instructions
Upload a file by dragging or clicking
Select the hash algorithm(s) to compute
View the generated hash values
Copy hashes for comparison
Verify against expected hash values
Notes
- SHA-256 is recommended for most security applications
- MD5 is fast but not collision-resistant
- SHA-512 provides the highest security level
- Hash computation is done entirely in the browser
FAQ
Which hash algorithm should I use?
SHA-256 for general security, SHA-512 for highest security, MD5 for quick checks (not security-critical).
Is the file uploaded to a server?
No, all hash computation is done locally in your browser. Files never leave your device.
