SQZSoft Secure Notes

SQZSoft Secure Notes is a personal information management database. All notes information are encrypted by AES then stored to database.

Features:

• Add / Edit / Remove notes
• Change whole database password
• Export all notes to .txt file

How it works:

1. Get user password from login screen;
2. Calculate MD5 value of the password: MD5(password)
3. The database also have stored the MD5 value of real password;
4. Compare the calculated MD5 value and the MD5 value in database;
5. If correct, then calculate the SHA1 value of the password, this value will be the AES key;
6. Use the AES key to encypt / decrypt the notes data. So all notes data will be stored as encrypted data.

Fixed some bugs.
