Batch Programming: Lesson 8 (Advanced encryption/decryption script)

[@semvandelft5310]

I learned more from this series than from all the other things i found together and its even 7 years old now.

[@ruthlessdraculigula1051]

This is the coolest batch programming video on KZbin.

[@technologycrazy]

Wow. I’m watching this 7 years later. There are certainly easier ways to accomplish what I was doing. But if you somehow make it through this lesson (and understand it) you have graduated. It may take a few watches. Once complete, you should go on to more advanced programming languages and truly appreciate how weird this language is.

[@yourfrienben8097]

Thanks so much this has started to fix my boredom problem. Its really fun to see what you made at the end

[@personpersoon3332]

After an our of googling this is the best tutorial I have found very well explained and nice results

[@meloonaticmelons]

Thank's! I tried creating my own encrypter and decrypter my self but I ended up having to search on youtube for a tutorial! This video was a lot of help!

[@joshuamacdissi6428]

Loved this series, although you're correct about the headache. I got a headache after watching the entire series all the way through. :P

[@astric32dll]

THANK YOU SO MUCH. I watched all of your tutorials, now i'm out here making an OS in batch.

@codestop @technologycrazy Codestop, meet technologycrazy. You guys are awesome and thanks for the tutorials. Ive reached the end of both of your series.... for now... CANT WAIT FOR MORE!!!!!!

[@kingofheartsblazing-8235]

Thank you so much Technologycarzy for making this Batch series. Now I know what to do and I am free to make some codes. Thank you so much. That deserves a like on each Batch series video. :D

[@technologycrazy]

And it's live! 25 Min batch programming special. Enjoy :)

[@9090jet88]

thank you for teaching me and a lot of other people how to write code with batch

[@runefisk2112]

If i could, i would like all you batch programming videos a thousand times!!! I have been searching on youtube alot, and after 3 days i could do all the thing, the videos were showing. But then i watched number one of this series, and it was already a bit more than all the other videos, so i kept watching, and I am satisfied. Your videos are awesome, and you are awesome!!!

[@zvava]

what video recorder do you use?

[@playerguy2]

runefisk2112 i know right, they are great!! keep uploading!

[@SilichipX]

These are great tutorial videos, I have added your playlist to my 'Cmd Vs Bat' video. 😉👍

[@technologycrazy]

Copy the code from the description. Sounds like you forgot to put !'s around the chars variable

[@bigsteamfan]

Very nice video, and very nice series overall man. You're really a good teacher. Might wanna consider becoming one in the future. :). Thanks for all of the effort put in this, and we hope to see more interesting stuff from you in the future.

[@tyzorg]

Holy hell you are a GURU! thank you for this guide.

[@Nextracer1]

It bugs me how he says "de-encryptor"...

[@PopFox]

"this copy of windows is not genuine"

[@technologycrazy]

I should Clarify two things 1) This was meant as a lesson, not create the worlds most secure encryption. It's more secure then basic "a=b,b=d,d=c" encryption but is not nearly as secure as real life 128 bit encryption. 2) There is more then one way of doing everything. If you find a different way let me know in the comments below. After re-watching the video I have already found some shortcuts I could of taken. Can you find them? Have fun! Code used is in the description.

[@vinceypma8962]

You can adjust the copy/paste behavior in the Command Prompt Properties dialog box.

Thankyou so muchh!!! This has been super helpful. You explain everything so clearly. Thanks again! Subbed!

[@kingofheartsblazing-8235]

He did it well

[@tedgames2052]

I converted these to executable jar files (EXE) and placed them inside c:\Windows\System32 and now I can run them as a command inside the command prompt (CMD). Now I'm gonna work on making a batch file that starts cmd and changes the directory to a folder where I will have my own custom EXE files for a custom command prompt with my own commands. I have a feeling this will be a big, big, BIG project.

if i wanted to be able to use numbers in the chars line how would i do that as when i try with inputcode=1 and i do somthing simple like hi and get tons of random numbers that cant decode

[@ashokadhikari4843]

what is difference between !code! and %code%? also it will only encrypt 1st line......how to do multiple lines?

[@themightyhacker9564]

!code! is the latest code and %code% is not the latest code.

[@Xjag]

Ok so I'm trying to make a game in batch, but I'm wondering if either you could make a video on it or someone can explain it to me 1. Save and load feature Saves your current progress and load it when you continue 2. Randomized scenarios You put in an area a bunch of scenarios and batch will randomly pick one of the scenarios you have

[@looserrip2688]

Royal Roach sadly i don't know how to do random numbers, but what i DO know is that you can save & load progress with textfiles, like this: @echo off set level=2 echo level:%level > data.txt ---------------------------------------------------------------------- check episode 3 to get information about LOADING things from the file.. i forgot lol

[@RRKS_TF]

You have probably given up on this project or figured out how to do it but... Save and load feature. Get your game to echo %data1% >> %savename%.bat And the %random% isn’t the best but it works just fine from what I’ve found. If it isn’t random enough you could try and make your own. Oh and don’t set variables like %time%, %random%, %date% as they are system variables. There are a few others but I can’t remember the rest of them Code=%some algorithm for names%-%gold%*%xp% Ran=%hp%+%dmg%*%code%/(%gold%+%xp%) The problem with this is it is going to need to be ran the line before the %ran% variable is needed so not the best, and my example isn’t exactly that random. If you start with the same name then it will not, at first be random but as they get gold and xp as well as any damage and health upgrades it will become a bit harder to predict

[@mnokeee]

batch isn't really that good for games, try c++ or c sharp, but the random number scenario thing would have to do with an encryptor I think

[@aharobal]

There is a 404 error when you try to download the files. Pls help!

[@queueibrown7217]

Good job this help i would like to know how to create folders with today's date, can this be done?

[@Myrslokstok]

Gret stuff you should do a #9 where the same letters do not get encrypted to the same numbers that should be a much stronger encryption.

[@NehorayPerets]

please upload more lessons, I like it.

[@HaQuase30Anos]

the "get rid of the dashes" part is nonsense. In the last loop just set "code=!code:-%%F=%%C! other than that, great

Is there a way to make it distinguish between capital letters? the id for "t" is 29 and when I put a "T" in it comes out 29 even though I expanded the range and added the capital letters to the lowercase letters. when I do %%c=%%N it give the capital letters a number but when I run it it says that a capital "t" is a lowercase "t". Please help! Thanks and I love the videos they've really helped me

I want to decrypt other things with the decrypter, but it doesn't work , what should i add to my decrypter to decrypt other things?????

[@stijnveenman]

What do you mean with other things After the alphabet you add the other things you want then you take the number off symbols and change the 36 to your amouth +10

[@yorgos_p]

I want to decrypt wireshark hashes.

[@stijnveenman]

Then you would have to have their code

[@playerguy2]

or figure it out for your self.. but id listen to him ^

[@stijnveenman]

figuring it our would be impossible as you dont know anything about it, you would have to test every instance wich are prity mush endless so even with a special program that would try it out it would take years maybe even forever if you wanna try though gl

im trying to make a operating system with batch. theres a desktop and how you go to programs you put a command. for example if you type calc it should open calc. well it dosent work. is this the right code? if %app% == write goto write

[@Randomguy-ys8yz]

Ohhhh! I hate that ifs, they work sometimes and sometimes they dont. But, you can use: Set /p app= goto %app% Instead of set /p app= If %app%==calc goto calc The problem is, you type a var thet doesnt exist and it closes.

[@bigboi9313]

Is there An alternative to that squiggle in the chars:~ code?

[@jiaming5269]

I personally feel that batch programming is a lot of a hassle to do stuff, so what I do is use python as a programming language because it's easier to program in, and type something like "import os ; os.system('echo Hello world!!')" to be able to access cmd commands with Python.

[@jiaming5269]

I managed to make a better way of encryption and decryption including symbols :D so proud of it!! Although I didn't need Batch programming I made it completely with python

[@TheUltimateRPG10Official]

Python is more difficult to syntax than batch. I learned python a few years ago, but I learned batch all the way back in Kindergarten, to 3rd grade. So that's why most people use batch, since it's that simple to learn.
