GL8 Password Manager

GL8 is a password manager built in C# using the Windows Forms framework with MaterialSkin controls. The application focuses on strong encryption, data privacy, and ease of use. It provides users with an intuitive interface to manage their passwords and sensitive information, offering features such as search, CSV import/export, password generation, and encryption using modern cryptographic algorithms like Argon2, AES-256, Bouncy Castle.

• This is a hobby project in its early development stage. Any feedback that could help with its development will be appreciated.
• Always make a backup of your data (you can use the CSV or JSON (recommended) export function for that) decrypted or encrypted backup in .dat format.
• Create strong, atleast 8 characters long master password. Store your master password in a safe place, outside of your device.

To update your application from an older version, please follow these steps:

1. Backup Your Data:

   • Open the application and navigate to Settings.
   • Click on Backup to create a backup of your current data.

2. Export Data as CSV:

   • While still in Settings, select Export JSON.
   • Save the exported .json file to a safe and easily accessible location.

3. Prepare for the New Version:

   • Close the application if it's running.
   • Navigate to your application installation directory.
   • Important: Delete all files except the Backup folder. This ensures your backup remains intact.

5. Import Your Data:

   • Launch the updated application.
   • Go to Settings and select Import JSON.
   • Choose the .json file you exported earlier.
   • Note: When prompted, select semicolon as the delimiter during the import process.

6. Clean Up:

   • After confirming that your data has been successfully imported, you should delete the .json file.
   • To permanently delete the file on Windows, select it and press Shift + Delete.

Additional Tips:

• It's recommended to keep a copy of the .csv or .json file until you're certain everything is working correctly.
• If you encounter any issues during the update process, consider restoring from the Backup folder using your old program version or contact me for assistance.
• Whole process will be improved in future versions.
