A simple text based cryptography app that allows users to encrypt and decrypt text using various encryption algorithms. It uses a modular design that enables the addition of new ciphers with ease. The ciphers are implemented in python and only the root admin can add and remove them.

App: https://text-crypt.netlify.app/
API Documentation (Swagger UI): https://textcrypt-api.onrender.com/api-docs/

Read-only Admin Email: [email protected]
Read-only Admin Password: readOnlyAdmin123

Visitors (not signed up users) can encrypt/decrypt text with available ciphers

Users who sign in:

• Have their usage history saved and accessible whenever they login
• Get to select and work again on their saved usage history records
• Get their own dashboard with options

Root Admin users have access to the admin dashboard to:

• Manage (view, add, remove, modify) cipher information.
• Manage (view, add, remove, modify) all registered users

Read-only admins can only access the admin dashboard but cannot add, remove, or modify any of the resources in the app

The app is fully responsive and functional on any screen size

The app's theme can be switched between light and dark mode

Users who have forgotten their password can reset their password using a One Time Password (OTP) sent to their email

After a user signs up and generates some history, the select button on a history record at times don't work. This is due to improperly managed local state of the history context. Will be refactored and fixed in a future commit.
