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

Hi you guys, It's great when you send the source code of this video to me, please, I really really need it
github.com/nix1947/javasecurity
Nice video I like it. Informative and to the point.
Nice video I like it!
very good explanation, I was looking for a video showing how to do this, and this video really helped me, love from iran. <3
I liked the video. The instruction seems really helpful and clear !
Thanks prof for helping me the presentation ❤❤❤❤
Great !!
Nice video!
Can you deploy RMI in Wildfly?
Your way of explanation is damn good. Tried learning from different videos but your way of explaining by writing code is very helpful. Thanks bro.
Thanks Manoj bro
Excellent video! Incredibly insightful and relevant. It remains valuable and beneficial even to this day.
Can't it block the apps? Eg. FB, Insta etc
It's been a daunting task for me, designing a database schema for my django models... Nice video😅😊
how do I connect WiFi camera to tp-link router?
15:35
really helpful, thank you sir
thank you
What's the benefit of this?
The one thing that is so obvious here, is that VSCode has bad intellisense for Java 🤣
bro, websites are not accessed on system but the apps are working as usual and you please guide how to block the apps as well
what u say the apps are working means when connected to the network the app runs uh?
You have Nepali accent.
toh kya
2022 still helping thank u for your help
