About File Checksum Verifier
Verify file integrity by calculating and comparing cryptographic checksums. Upload a file and the tool will calculate all hash algorithms (MD5, SHA-1, SHA-256, SHA-384, SHA-512, CRC32) simultaneously and automatically detect which one matches your expected value.
How to use:
- Step 1: Enter the expected hash value (optional)
- Step 2: Upload a file
- The tool will calculate all hash algorithms automatically
- If you provided an expected hash, matching algorithm will be highlighted
Supported Algorithms:
- • SHA-256: Recommended for general use (256-bit)
- • SHA-512: Maximum security (512-bit)
- • SHA-384: High security (384-bit)
- • SHA-1: Legacy support (160-bit, deprecated)
- • MD5: Legacy support (128-bit, insecure)
- • CRC32: Error detection (32-bit, not cryptographic)
