NoteDelight encrypts its database using SQLite3 Multiple Ciphers (sqlite3mc) in SQLCipher v4 compatibility mode. Exported .db files can be inspected with any tool that supports SQLCipher 4.
| Tool | Minimum version | Notes |
|---|---|---|
| DB Browser for SQLite | 3.12.x | Must be a build with SQLCipher support. The default Linux package (apt install sqlitebrowser) usually ships without it — use the official AppImage or macOS / Windows installer instead. |
or sqlcipher CLI |
4.x | apt install sqlcipher (Linux) / brew install sqlcipher (macOS) |
Tip: Run
sqlitebrowser --version— the output should mention SQLCipher. If it only shows a plain SQLite version the build does not support encrypted databases.
- Open the desktop app and sign in with your password.
- Go to Settings → Backup → Export database.
- Choose a destination path and click Save.
The exported file is an exact copy of the encrypted database.
- Launch DB Browser for SQLite (the SQLCipher-enabled build).
- File → Open Database… and select the exported
.dbfile. - A "SQLCipher encryption" dialog appears.
- Configure the dialog:
| Field | Value |
|---|---|
| Password | Your NoteDelight password |
| Encryption settings | SQLCipher 4 defaults |
| Page size | 4096 |
| KDF iterations | 256000 |
| HMAC algorithm | SHA512 |
| KDF algorithm | SHA512 |
| Plaintext Header Size | 0 |
- Click OK. The database structure and data should now be visible.
sqlcipher /path/to/notes.db
sqlite> PRAGMA key = 'your_password';
sqlite> .tables
note sqlite_sequence
sqlite> SELECT * FROM note;| Symptom | Fix |
|---|---|
| "file is not a database" after entering password | Verify you selected SQLCipher 4 defaults (not SQLCipher 3 or Custom). |
| DB Browser doesn't show an encryption dialog | You are running a build without SQLCipher. Download the AppImage from the official releases. |
sqlcipher CLI says "Error: file is not a database" |
Make sure PRAGMA key is the first statement executed on the connection. |
| Platform | Encryption library | PRAGMA cipher_version result |
|---|---|---|
| Android | SQLCipher (Zetetic) | e.g. 4.6.1 community |
| iOS | SQLCipher (CocoaPod) | e.g. 4.5.5 community |
| Desktop (JVM) | SQLite3 Multiple Ciphers | e.g. SQLite3 Multiple Ciphers 2.2.7 |
| Web | sql.js (no encryption) | N/A |
All platforms that support encryption produce databases compatible with the SQLCipher 4 format.
