dSign

Final Project for EC552

dSign is locally run software for designing an encrypted DNA signature. This web-based software allows for secure sharing and allows you to place your signature in any sequence you input. The software is designed with the intention of being open source and of accessing a remote database. However, due to the developers' limited resources we currently are not hosting a remote database. So, to utilize dSign's features follow to Installation Instructions to run the software locally. And then follow the webpage Instructions to generate encrypted signatures and sequences.

Installation Instructions:

1. clone the reponsitory on your machine:

git clone https://github.com/lraiff/dSign.git

2. Install XAMPP and run the Apache and SQL servers. Installation: https://www.apachefriends.org/index.html After installation, find the xampp program file and the xampp-control application. The correct servers will run if your control panel looks like this:

3. Navigate to: http://localhost/phpmyadmin/index.php Create a database called "login" and a table called "users". In the table make the following columns:

4. Copy all the files in the code folder of the cloned repo and place them a newly created folder with the path: ~/xampp/htdocs/dSign

5. Navigate to: http://localhost/dSign/

*** If the installation doesn't work make sure you have python installed on your laptop and that you have the following modules installed***
Necessary python modules:
Use pip to install the following libraries:
json
numpy
base64
cryptography
Fernet
hashes
PBKDF2HMAC
wrap

Using the Webpage Software

1. Register as a user on the software - username can be anything but password must be 10 characters long. (E.g. @rTW1nR56g or RTerTFWoOP)
2. Login with your login details.
3. Click "Signature" in Navigation bar to enter personal information for composing the unique signature. This encrypted signature will be displayed on the Profile.
4. Once you see the signature displayed, add new sequences using "Add Sequence" button.
5. On your Profile page, View, Send, Export, or Delete your sequences using the respective buttons.
6. If Exporting, the JSON file will be available as seq#.json in your local "project" folder.
7. If Sending, the datacode.key and public.key files will be in your local "project" folder. To have guests access the sequence, send them both files.
8. If you are a guest, upload both datacode.key and public.key files to "Guest Login" page accessed on Home or Guest at Navigation bar.
