Why Validate Checksums?
- • Verify downloaded files haven't been corrupted
- • Detect malicious file modifications
- • Ensure file integrity during transfer
- • Confirm backup accuracy
What is Checksum Validation?
Checksum validation is the process of comparing a calculated file hash with an expected checksum value. If they match, the file is intact and hasn't been modified. If they don't match, the file may be corrupted or tampered with.
When to Validate Checksums
- After Downloads: Verify software, ISOs, and large files
- File Transfers: Ensure files weren't corrupted during transfer
- Security: Detect malicious modifications to files
- Backups: Confirm backup files match originals
- Updates: Verify system and software updates
How to Use
- Select the file you want to validate
- Choose the hash algorithm (usually provided by the source)
- Paste the expected checksum (from the download page or documentation)
- Click "Validate Checksum" to compare
- Green checkmark = file is valid, red X = file may be corrupted
