Filhash
Vad är Filhash?
File hash generates checksums (MD5, SHA-256, etc.) to verify file integrity and identity. Detect tampering or duplicates.
Hashing is computed locally. Files never leave your device.
När ska man använda?
- Integrity check: Verify downloads match originals
- Deduplication: Find duplicate files by hash
- Security: Confirm file authenticity
- Backup verification: Ensure backups are correct
Fördelar
- Multiple algorithms: MD5, SHA-1, SHA-256, etc.
- Fast: Quick local computation
- Privacy: No upload
- Batch: Hash multiple files
Vanliga frågor
A unique fingerprint of file content. Same content = same hash.
SHA-256 is recommended. MD5 is quick but not cryptographically secure.
Hur man använder
- Upload: Add file(s) to hash
- Select algorithm: Choose MD5, SHA-256, etc.
- Compute: Generate hash values
- Copy: Use hash for verification
Tips: Use SHA-256 when security matters.
