Secure Notes is a Joplin plugin that lets you password-protect and encrypt your notes locally. It ensures your sensitive information stays private — only you can unlock and read your data.
- 🔒 Password-Protected Notes - Encrypt sensitive notes with a password of your choice
- 👁️ Read-Only View - Preview encrypted notes without decrypting them permanently
- 📁 Local Storage - Encrypted notes are stored locally in Joplin's database
- 🛡️ Strong Encryption - Uses industrial level AES encryption with Webcrypto API.
- 🔄 Multiple Modes - Supports AES-CBC, AES-CTR, and AES-GCM modes with 128-bit or 256-bit key sizes.
NO RECOVERY - If you forget your password, your encrypted notes are permanently lost. There is no recovery method, no reset option. It is recomended to maintain backups of important data.
NO WARRANTIES - This plugin is provided "as is" without any guarantees. While it uses industry-standard AES encryption, no system is 100% secure. The author is not liable for data loss or security issues.
