File Encryption Decryption

In the previous post we saw about the text level encryption app RSA.

Now I have created an app for file level encryption decryption. The app uses AES algorithm for encrypting the files.

If you don't know ow AES works not to worry. check this video

The app uses 3rd party lb called file picker for choosing its files. This is easy to understand library with minimal documentation you have to go through their code available in GITHUB for understanding.

The AES version that I have used is AES-512. So the password size must be exactly 16 characters.
Below is different AES versions and their respective iterations.

AES|	Key-lengt|	Round
128	4	10
192	6	12
256	8	14
320	10	16
384	12	18
448	14	20
512	16	22
576	18	24
640	20	26

Steps:

1. Encryption

Requirement: 16 character password & File(size below 10 mb).

2. Decryption

Requirement: 16 character password & Encrpted File.

The app is minimalistic and performs its intended function.

Good Luck !
