This project explains about how to encrypt and store data in android shared preference and how to decrypt it. Tested in android 4.4 to android 8.1.

The purpose of this project is to encrypt and decrypt photos using the AES algorithm with a one-time use 128-bit AES session key wrapped with 2048-bit RSA encryption.
