Cryptography Android App Part 2 | Encryption and Decryption Algorithms in Java | Semester Project

This app is the semester project work as it combines two technologies Android and Cryptography.
What is Cryptography?
Cryptography is a method of protecting information and communications through the use of codes, so that only those for whom the information is intended can read and process it. The prefix "crypt-" means "hidden" or "vault" -- and the suffix "-graphy" stands for "writing."

What is Encryption?
Encryption is the process of encoding all user data on an Android device using symmetric encryption keys. Once a device is encrypted, all user-created data is automatically encrypted before committing it to disk and all reads automatically decrypt data before returning it to the calling process. Encryption ensures that even if an unauthorized party tries to access the data, they won’t be able to read it.

What is Decryption?
Decryption is the process of taking encoded or encrypted text or other data and converting it back into text that you or the computer can read and understand. This term could be used to describe a method of unencrypting the data manually or unencrypting the data using the proper codes or keys.

These all things are combined into an Cryptography Android App. We've used custom encryption and decryption techniques or algorithms in Java for this Cryptography Android app.
You can watch these videos and make this app via watching the playlist of Cryptography Android App.

Hi my input is encoded but not decoded can u pls help

[hrushikeshpatil]

which algorithm is used here for encryption and decryption ??

[Discoverer-of-Teleportation]

Pls make this apps in kotlin as it is announced as official for Android studio

[bisharatsj]

I use this, encrypt and decrypt code in android studio but my decoded msg Return me invalid
