ZIP File Security
Password Protection
ZIP files can be encrypted with passwords. AES-256 encryption is the gold standard.
AES-256 vs ZipCrypto:- AES-256: Modern, secure, recommended
- ZipCrypto: Legacy, vulnerable, avoid if possible
Safe Sharing Practices
- Share passwords separately: Never send the ZIP and password in the same message
- Use strong passwords: 12+ characters, mixed case, numbers, symbols
- Verify recipients: Confirm you're sending to the right person
- Delete after delivery: Remove temporary ZIP files
Common Security Mistakes
- Sending password in the same email as the ZIP file
- Using weak passwords (names, dates, common words)
- Not encrypting sensitive documents
- Reusing passwords across multiple archives
- Forgetting to delete old archives
Malware in ZIP Files
ZIP files can contain malware. Always:
- Scan ZIP files from unknown sources
- Don't extract files you didn't expect
- Verify the sender is legitimate
- Keep antivirus software updated
