Encrypt and Decrypt Images Using the Two Fish Algorithm in Java

In this video, we will dive into the implementation of the Two Fish encryption algorithm in Java to securely encrypt and decrypt image files. Two Fish is a symmetric key block cipher known for its speed and flexibility, making it a great choice for secure data encryption.

What You'll Learn:
How to read and convert images to byte arrays in Java.
Generating random encryption keys and initialization vectors (IV).
Encrypting image byte data using the Two Fish algorithm with CBC mode and PKCS5 padding.
Saving encrypted data and IV to files.
Reading encrypted data and IV from files.
Decrypting the encrypted image data.
Converting decrypted byte data back into an image.
Writing the decrypted image to the file system.
Code Overview:

Here's a brief outline of the code we will be working with:

0:15 Register Bouncy castle
0:35 Read the image
1:53 Convert input image to byte array
3:08 Generate TwoFish Secret key and IV
4:40 Encrypt the image using two fish algorithm
6:27 Save encrypted image to a file
10:00 Read encrypted image from filesystem to decode
12:15 Decode encrypted image
14:58 Convert decoded image to original image
16:30 Save decoded image to file system
