About File Hashing

File hashing generates a unique fingerprint for any file. Compare hashes to verify file integrity, detect changes, or confirm downloads completed successfully.

Common uses:

Verify file integrity after transfer
Detect unauthorized file modifications
Confirm software downloads are authentic
Digital forensics and evidence handling
Duplicate file detection

File Hashing Applications

Integrity Verification

Download Verification: Confirm files downloaded correctly

Transfer Validation: Ensure files weren't corrupted during transfer

Backup Verification: Verify backup copies match originals

Security Uses

Tamper Detection: Identify unauthorized file modifications

Forensic Analysis: Create evidence fingerprints

Malware Detection: Compare against known good/bad hashes

Development Workflows

Build Verification: Ensure compiled artifacts are identical

Deployment Validation: Confirm correct files are deployed

Version Control: Track file changes over time

Supported Algorithms

SHA-256	64 chars	High	Production, Bitcoin
SHA-1	40 chars	Low	Legacy compatibility
MD5	32 chars	Broken	Non-security checksums
