General
Is this an official build?
No. This is an unofficial community resource focused on a Windows portable build that includes SQLCipher support. Always verify downloads and check the official repository for authoritative information.
Is there an installer?
We focus on a portable Windows build (no installation). If you specifically need an installer, consult the official project/community releases.
Which Windows versions are supported?
The portable build targets Windows 10 and Windows 11. For older versions, test cautiously and refer to official notes.
Downloads & security
How do I download the portable build?
Go to the Download page. We use a CAPTCHA gate to prevent automated scraping. No direct file links are present on the site.
Why is there a CAPTCHA?
It reduces bot scraping and keeps links healthy. After successful verification, the widget opens the download in a new tab.
SmartScreen or antivirus warns about the EXE — what should I do?
Right‑click the file → Properties → Unblock (if available), then run once. Alternatively add the file to your AV allow‑list after verifying the source and checksums where available.
Can I verify integrity of the download?
Where checksums are provided, compare the file’s hash (e.g., SHA‑256) against the published value. Keep backups and verify after extraction.
SQLCipher & databases
How do I open an existing SQLCipher database?
Provide the correct passphrase and ensure parameters match (page size, KDF, HMAC). See Open an Encrypted DB and SQLCipher basics.
‘Wrong key’ error — how do I fix it?
Usually a parameter mismatch. Confirm the DB’s page size/KDF/HMAC and try again. Follow the Wrong key errors guide and retest.
How do I migrate from plain SQLite to SQLCipher?
Back up → create a new encrypted DB with standardized parameters → import → verify → swap. See Migrate to SQLCipher and Encrypt / Decrypt.
Import/Export & performance
Can I import or export CSV files?
Yes. Use the Import/Export features. For large datasets consider chunked imports and indices. See CSV Import/Export.
Performance feels slow — any recommended PRAGMAs?
Review Performance Tips for practical PRAGMAs and post‑import maintenance (VACUUM/ANALYZE).
Where can I find useful PRAGMA/SQL commands?
Check the CLI / PRAGMA commands cheat sheet with examples and notes.
