파일 해시

는 무엇인가요?파일 해시？

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.

언제 사용하나요?

• Integrity check: Verify downloads match originals
• Deduplication: Find duplicate files by hash
• Security: Confirm file authenticity
• Backup verification: Ensure backups are correct

장점

• Multiple algorithms: MD5, SHA-1, SHA-256, etc.
• Fast: Quick local computation
• Privacy: No upload
• Batch: Hash multiple files

자주 묻는 질문

1. Upload: Add file(s) to hash
2. Select algorithm: Choose MD5, SHA-256, etc.
3. Compute: Generate hash values
4. Copy: Use hash for verification

팁: Use SHA-256 when security matters.
