Generate cryptographic hash values (checksums) for your files to verify integrity and authenticity.

Generated Hash:

How to Use the File Hash Generator

Choose File: Click "Choose File" and select the file you want to hash
Select Algorithm: Choose SHA-256 (recommended), SHA-1, or MD5 from the dropdown
Generate Hash: The hash will be calculated automatically when you select a file
Copy Hash: Copy the generated hash value for verification or storage
Verify Integrity: Compare with known hash values to verify file integrity

File Hash Tips & Applications

File Integrity: Verify files haven't been corrupted during transfer or storage
Security Verification: Confirm downloaded files match publisher's checksums
Duplicate Detection: Identical files will have identical hash values
Digital Forensics: Create evidence chains and verify file authenticity
Backup Verification: Ensure backup files are exact copies of originals
Software Distribution: Verify software downloads haven't been tampered with
Version Control: Track file changes by comparing hash values

SHA-256: Most secure and recommended algorithm. Produces 256-bit (64 character) hash values.

SHA-1: Older algorithm producing 160-bit (40 character) hashes. Less secure than SHA-256.

MD5: Legacy algorithm producing 128-bit (32 character) hashes. Not recommended for security purposes.
