Basic Encryption And Decryption In Java #40

[@alexlorenlee]

If you’re new to programming but want a career in tech, I HIGHLY RECOMMEND applying to one of Springboard’s online coding bootcamps (use code ALEXLEE for $1,000 off): bit.ly/3HX970h

Hello Alex, I haven't seen anybody who can explain so simple so good to understand Java as you. God bless you. Greetings from Albania.

[@michaeltheisen]

Hey Alex I started watching your videos to help me understand how to code Java when I first started my classes. Lo and behold, here you are helping me again in my Cryptography class. I graduate next month! Thank you for helping me get this far.

[@chrisk.9469]

Honestly these are rlly cool, if we could do a mini series abt encryption id love it

[@kris_jnr_electrical]

THIS IS THE BEST ENCRYPTION TUTORIAL ON THE INTERNET. AM A PRO IN PYTHON . I LEARNT THE HARD WAY SO SAD I DIDNT SEE YOUR VIDEOS WHILE I WAS STRUGGLING LEARN YEARS AGO. ILL GIVE YOU A FOLLOW

[@oluwatobilobaodebo6992]

Final Exam Tomorrow, Thanks for the help throughout the semester Professor Lee!

good luck!

yo how'd it go

[@shehzadadeel32]

After searching for 3 days (few hours per day) I came across this video. I wish you could understand the happiness I am feeling right now after seeing your video. You are the best...!!! Thanks for your videos. keep it up.

[@TomJMumford]

This was part of my assignment for my first year of uni. You made it sound so easy. Thanks! :)

[@statxs]

I've been watching your tutorials from like 2 years ago and i finally stumbled upon a recent one! Thanks for all the hard work.

[@Anthony-wg7fn]

This was great. Can you please expand on this topic and talk about how to implement those other methods that take more steps?

[@dyln1k]

I have my AP comp sci test tomorrow and your vids are really helping me, thanks!!

[@smokinamby]

I find some people hard to understand, but you my friend. You have something about the way you explain stuff that makes things alot easier to understand than most other people that try and teach the exact same concepts. Your videos almost never fail me, somehow. Just wanted to say thanks for the help. For the love of god, get some dark mode goin on...

[@JustPassingByHere]

Amazing work Alex keep it up you motivate me to keep working at this stuff!

[@indomitablehumanspirit8320]

Alex i fuckking love you man I swear I am learning this right now in my class and I don't understand shit but because of you I have finally understood it tysm

[@milannovic5820]

It's like you are reading my mind. I was looking couple hours ago do you have a lesson about this. Keep up with good work and big support from Bosnia and Herzegovina 😃👍

[@stephen9849]

Better than md5! Less used, better secured!

[@codinggeek5230]

Thank you Alex Lee, for a wonderful tutorial

[@darthcode59]

Hey Alex I learn java from your channel and i did a different version of encryption. I did the program yesterday and today i see you have uploaded it a month ago!

[@AzureKnight]

thnx a lot brother just studying a night before for the exams

[@av2678]

Alex: some things like key always confused me But i didnt got confused Cz learnt from you Thx Alex, you inspired me so much for programming

[@woolly9468]

Alex: "Let's say the message is, 'hey, hows it hanging?'" Me: *puts "its the Russians"*

Helpful and subed. Greetings from Tanzania 🇹🇿

[@cinephile9015]

Well Explained Alex. Can you make a video on Threads it would be helpful.

[@ultra_xd]

Hey Alex, I was wondering if you could do a tutorial on serialization so I could save my objects into a file. It would be very much appreciated! Thanks! P.S Your videos are awesome.

[@Kizuki25]

Helped me complete a caesar cipher lab thanks!!!

[@efeaydemir1413]

thanks mate, very easy to understand !

[@johncarlodiaz3829]

Hello Alex, can you make a video about making a database using mySQL?

[@astronautcowboy2142]

This was so awesome to see! I want to make tons of encrypted messages now haha.

[@danow11]

Great example. Working on this in my class and they did not do a great job of breaking down the steps in a simple way as you did. It was more like you will need to do this,this,this(using arbitrary descriptions) in some order, figure it out.

[@mannyokafor4609]

do a Annotations video pleasee

[@swapnasamparnasahoo7736]

thank you so much,it helpedme a lot

[@definitlyarealperson7041]

Amazing video! What peoples do in a 100 lines of code you put in just 20!

[@Ms_Oszy]

It so cool , this called Ceaser Cipher, Encrypt to ge Cipher C as C= char+key, decrypt the restore original message m as, m= C-KEY.

[@Sammym2001]

I love your Java tutorials and they are very good at helping me remember a lot of concepts that I have probably forgotten in Java but unfortunately, my university teaches C++ and I was wondering if you have any plans to make any videos regarding C++ either on this channel or another channel.

[@HarshRajAlwaysfree]

I always wanted to watch a video related to this topic

[@reivax8419]

Could you cover bitmaps? And also great video

[@mansoorahmad9564]

Love it thanks alot brother

[@thebinsohail]

public class Encrypt{ public static void main(String[] args) { int salt=(int)(1+(Math.random())*9); String string="Hello World"; System.out.println(string); char [] chars=string.toCharArray(); for(char c:chars){ c+=salt; System.out.print(c); } } }

[@hi-vk2sm]

Hey Alex, could you do a tutorial about bitwise operators (^=, >>,

[@HarshRajAlwaysfree]

Can you make a video on making a simple game like fappy bird with Java ?

[@habibishapur]

if you want to make games look at c# or c++ instead oj java. hell maybe even python

[@mr_confuse]

Fappy Bird, sounds interesting indeed

[@markanthonyzara3464]

Alex do you know how to encrypt / decrypt file using java?

[@__-cd1nd]

Thanks for your help🙏🏼

[@CodingKida]

One of the best logic.

[@Oismyurl]

Hey man. Great video! Any chance you could do something on Threads? :D

[@sivakrishnat5471]

Hi Alex, it is a nice video. also, please make a video on session keys and encryption.

[@AvivaScott]

Does the algorithm you used to encrypt/decrypt have a specific name? Thanks! Great tutorial

[@maxpeng3000]

I think it’s called caeser cipher

[@jeafearn2097]

sir, it's very helpful. is this a part of Caesar Cipher?

[@raneemayman7581]

what about asking the user to enter the key and enter a text how to write it? for Encryption and Decryption

Great stuff! :-) Thank you.

Can you tell me are this cipher is a Cesar?

real question. what is this encryption method called?

Hello can you make a tutorial on triple des encryption and decryption ? your video is really helping thx so much mate

[@2012mrmoh]

This type of encryption called caesar cipher

this is kind of cool

[@androidpc9656]

is there any name for this algorithm? and what happenns if we encrypt the last ascii character

[@jonathantremblay4722]

Thanks a lot !

[@MisterWealth]

Question: So what if you don't know that it's -6 for example?

[@IkeVoodoo]

You can't get the original message

[@sanjanajhurry6170]

this is symmetric encryption right?

[@mallickpriyanshuOG]

Can you make a video on some more complex encryption? And also encrypting all types of files

[@rmrishan5742]

Thank You very much for the tutorial. I have a question. so "c" is a char. the encrypted code that you are printed in the console is actually for loop running several times and change the data in "c" . let's say i want to get the output as a string. How could I achieve this?

[@Westsydney2000]

If you decide to use an app that has the best encryption, choose Utopia Ecosystem

[@amitpanc]

When I do c = c+5; it complains of "can't convert from int to char" while c += 5; works fine. Why?

[@samhou8897]

u should do c = (char) + (c + 5);

[@smokinamby]

The first part, When you said "when I do" you're assigning the value of c+5 to a variable named c. The second part of your question, you're comparing 2 values, not assigning values. So the first one you assigned a value. The second one you're comparing a value. Assigning vs comparing. One operator will assign. Two operators will compare.

[@smokinamby]

And the answer to your question is variable c is of type char. C+5 is an int (because it has a whole number). You cannot put an int into a char type variable. (Unless you cast it, which you'd only do if you're sure it's not gonna be losing any information). As I said in my last comment these are 2 completely different operations. The first operation you asked is ASSIGNING a value. The second operation you're COMPARING 2 values.

[@smokinamby]

Your first statement you are 'saying' put this value in c. Your second statement you're 'saying' while c has this value, do this.

[@adamlorbetskie3404]

@@smokinamby They're both assigning

anyone know how to do it so it does input = ABCDEF and the output = ZYXWV?

This was great, didn't know you could do easily convert strings into arrays character by character like that.
