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
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.
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.
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
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!
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...
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.
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
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 😃👍
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.
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.
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.
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.
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?

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

Final Exam Tomorrow, Thanks for the help throughout the semester Professor Lee!
good luck!
AP exam? 😂 I think I failed that.
Same men that’s why I’m here 😂😂
@@ivanarabome4172 I lowkey wanna know how his exam went
yo how'd it go
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.
Alex: "Let's say the message is, 'hey, hows it hanging?'"
Me: *puts "its the Russians"*
This was part of my assignment for my first year of uni. You made it sound so easy. Thanks! :)
Amazing work Alex keep it up you motivate me to keep working at this stuff!
I have my AP comp sci test tomorrow and your vids are really helping me, thanks!!

This was great. Can you please expand on this topic and talk about how to implement those other methods that take more steps?
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!
Better than md5! Less used, better secured!
Thank you Alex Lee, for a wonderful tutorial
You own my subscription , good video !

thanks mate, very easy to understand !
Well Explained Alex. Can you make a video on Threads it would be helpful.
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.
Helpful and subed.
Greetings from Tanzania 🇹🇿
This was so awesome to see! I want to make tons of encrypted messages now haha.
This helped me so much.
Helped me complete a caesar cipher lab thanks!!!
do a Annotations video pleasee
Thanks for your help🙏🏼
Love it thanks alot brother
thank you so much,it helpedme a lot
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
You made it so easy to subscribe :)
Very useful bro thank you😊😊😊
Great stuff! :-) Thank you.

Hello Alex, can you make a video about making a database using mySQL?
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.
I always wanted to watch a video related to this topic
Could you cover bitmaps? And also great video
Can you make a video on making a simple game like fappy bird with Java ?
if you want to make games look at c# or c++ instead oj java. hell maybe even python
Fappy Bird, sounds interesting indeed
thanks really understandable
thnx a lot brother just studying a night before for the exams
what about asking the user to enter the key and enter a text how to write it?
for Encryption and Decryption
One of the best logic.
This was very helpful.
Hope to learn more from you.

Question: So what if you don't know that it's -6 for example?
You can't get the original message
Hey man. Great video!
Any chance you could do something on Threads? :D
Thank you so much it clear explanation, I am wandering what if the input is a text file not an string, who to treat it?
What app is this where can I find this
When I do c = c+5; it complains of "can't convert from int to char" while c += 5; works fine. Why?
u should do c = (char) + (c + 5);
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.
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.
Your first statement you are 'saying' put this value in c. Your second statement you're 'saying' while c has this value, do this.
@@smokinamby They're both assigning
Can you tell me are this cipher is a Cesar?
Thank you legend!
real question. what is this encryption method called?
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
sir, it's very helpful. is this a part of Caesar Cipher?
Thanks a lot !
Does the algorithm you used to encrypt/decrypt have a specific name? Thanks! Great tutorial
I think it’s called caeser cipher
is there any name for this algorithm?
and what happenns if we encrypt the last ascii character
this is symmetric encryption right?
What compiler did u used?
Hey i have a problem when i ude space In my text i get an error message
Alex do you know how to encrypt / decrypt file using java?
Hi Alex,
it is a nice video. also, please make a video on session keys and encryption.
Superb.
Thanks buddy
Can you please do this in C#??
can you make a video on debugging please
How do i use the c variable outside of the brackets?
Now the question is how do you hide the key in such a way it’s unreadable to send it from server to device and vice versa
Can you make a video on some more complex encryption? And also encrypting all types of files
this is kind of cool
Amazing video!
What peoples do in a 100 lines of code you put in just 20!
Demn, that's awesome man....
good job bro
Awesome..😊
You're the BEST
Hello can you make a tutorial on triple des encryption and decryption ? your video is really helping thx so much mate
Can you plz make a video on threads in java. I can't understand it clearly
how would you make it so it doesn't encode numbers and special characters?
Great!
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.
thank you.
Thank u it's 😊
Please can you do a StdDraw tutorial
hey can you tell me how can i increase 1st char to 1 then 2nd char to 2 like each for each character
What if i dont wanna shift the non letter characters??
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.
How do i do this with files
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?
Goodday, what do you call this algorithm? i was so confused ☹️
Can you recommend me any good book for java?
anyone know how to do it so it does input = ABCDEF and the output = ZYXWV?
hey can somebody please explain that for loop to me.
I know the conventional format of for loop. this is new to me
but if we use c=c+1 instead of c+=1 , it is giving lossy conversion error
This type of encryption called caesar cipher
If the char is z again i want to repeat form a
If you decide to use an app that has the best encryption, choose Utopia Ecosystem
Hey Alex, could you do a tutorial about bitwise operators (^=, >>,
Don‘t forget Charlee :)! ☕️☕️☕️
How do we make a database with arrays
i wish i see this before activity, but my activity is already checked. haha
