TTD QR CODE

This application is a digital signature application that replaces a manual signature with a personal password. Digital signatures can also use passwords that are managed collectively through institutions but are more vulnerable to abuse. If in this application, the password is filled in making a digital signature (TTD QR), then the information is encrypted according to the password used so that only the TTD QR maker can find out the information. The encryption process uses Advanced Encryption Standard which is currently very safe because it is not easy to open information without knowing the password used. However, the encryption process becomes ineffective if the password used is easy to guess. Therefore, make sure the password used has an adequate number of characters and a combination of numbers, letters and / or symbols. Thus a TTD QR with a password can be used to verify the authenticity of signatures on important documents.

Hopefully this application can be useful especially for administrative matters and correspondence. Good luck!
