Troubleshooting CipherWall Self-Decryptor: Common Issues and Fixes
1. Decryptor fails to start
- Check system requirements (OS version, RAM, disk space).
- Ensure executable has correct permissions (run as administrator/root if required).
- Reinstall the latest version; verify download checksum.
2. Incorrect or rejected passphrase / key
- Confirm you’re using the exact passphrase (case-sensitive) or the correct private key file.
- If using a key file, ensure it hasn’t been corrupted — compare file hash to a known-good copy.
- Try any legacy passphrases or key aliases you may have used when encrypting.
3. Partial or corrupt output files after decryption
- Run integrity checks (checksums or included MAC/auth tag verification).
- If corruption is detected, attempt decryption with the original encrypted file copy; avoid modified copies.
- Restore from an earlier backup of the encrypted archive if available.
4. “Unsupported format” or version mismatch
- Verify the encrypted file was produced by CipherWall Self-Decryptor and not a different product.
- Check the decryptor’s version — older decryptors may not support newer file formats; update to a compatible release.
5. Missing dependencies or library errors
- On Linux, ensure required libraries (OpenSSL, libstdc++, etc.) are installed in supported versions.
- On Windows/macOS, install any bundled runtime (VC++ redistributable, runtime frameworks) the app requires.
6. Slow decryption performance
- Confirm CPU usage and I/O: decrypting large files is CPU- and disk-bound — use faster storage or more CPU if possible.
- Disable real-time antivirus scanning for the decryptor process or whitelist the decryptor and target directories.
- Check for network-mounted volumes causing latency; copy files locally before decrypting.
7. GUI hangs or crashes
- Try the command-line decryptor (if available) to isolate UI vs core engine problems.
- Clear user config/cache files (backup first) to remove corrupted settings.
- Review application logs for stack traces and report them to support.
8. Permissions / access denied on output files
- Ensure the decryptor process has write permissions to the destination folder.
- If decrypting to an external drive, verify the filesystem supports the file size and attributes.
- On Windows, disable Controlled Folder Access or grant the decryptor access.
9. Network or license activation errors
- Confirm system clock is correct; certificate/activation failures often result from incorrect time.
- Ensure corporate proxies or firewalls allow outbound connections to the product activation servers or use an offline activation method if provided.
10. Unable to find associated metadata or sidecar files
- Some encrypted packages rely on sidecar metadata (headers, manifests). Keep encrypted file and metadata together; check for renamed or moved files.
Diagnostic steps (ordered)
- Reproduce issue and note exact error messages.
- Check application logs (enable verbose mode if available).
- Verify file hashes for encrypted file and key files.
- Test with a small known-good encrypted sample.
- Update the decryptor to the latest release.
- If unresolved, collect logs, environment details (OS, version, decryptor version), and sample files and contact vendor support.
