For any sort of job it will be highly dependent on a lot of factors, such as: - Where you live - What you're interested in - If you can handle the risk associated with being a freelancer In general I would recommend getting a good understanding of computer science basics, and developing projects that demonstrate that understanding. Languages/frameworks change all the time, but those skills in computer science are universal. Also if python./django is the only thing you know, I would recommend learning at least 1 other framework/language so you have some additional relevant experience

@@canadiancoding so what fremework you recommend me with the fact that am from Ethiopia, and am i am really interested on freelancing and ready to take the risk around,?

Yes, so old wartime schemes you would leave with a physical ciphertext, and using that ciphertext you can just broadcast out in public over radio. Often different ciphertexts were given to people of different ranks so that messages could only be read by specific people in the field depending on the operation.

The version I explained in my video is not quantum secure afaik. I think you could make it EFFECTIVELY quantum secure if your note is long enough, but the protocol itself is not secure against quantum attacks. There are versions of the one-time pad that could be, but they're more complicated. I think what you're referring to is when people call the one time pad a "perfectly secret" scheme. All this means is that the ciphertext we use doesn't leak any information, meaning there are no side channel attacks. This is all a fancy way to say that you can't get information AT ALL about the content you're trying to encrypt, from how you encrypted it. Other methods will use the source text to generate their encryption, and so they are not "perfect secret" schemes. I can't cite sources in a youtube comment but if you google "perfect secrecy" there is a video on khan academy, and one on wolfram U that will explain the concept well. For post-quantum security there's a good channel called Chalk Talk here on youtube that cover quantum secured approaches like lattice-based cryptography.

This is actually a good point. I should have mentioned it during the video. If you watch the animation from 3:55 onward you will see every number is left-padded (add 0's to the left) to 8 bits. So every number is 1 byte, and if it can be stored in less bytes then it's just less efficient. This is because ASCII is a fixed-length encoding, whereas something like Unicode makes this more complicated. Hope that makes sense

There isn't any specific way to do this, ideally this is a step you would do "in-private", since if you do it "in-public" this part would need to be secured somehow (no specifics given in the OTP protocl). If eve is able to get ahold of the pad while in transfer then the whole system is no longer secure. One option is to do public-key exchange and then encrypt the pad with a key when you send it. Something like diffie-hellman can do this, which I created a repo to explain here: github.com/descent098/diffie-hellman Thanks for watching!

I did quite a lot of digging, and found something that *might* be true about this. To understand this you need to know a few things Python in general is written in C/C++, in C/C++ header files (.h files) are used to tell you about functions. There are a few common windows ones like windows.h. Looking into the source code for winreg it seems to be using windows.h, but it seems to also be using a function defined in another .h file called RegOpenKeyExW() (learn.microsoft.com/en-us/windows/win32/api/winreg/nf-winreg-regopenkeyexw), I do not know enough about the intricacies of C/C++ or windows to be able to confirm this, but it seems like this is what's being called by python (python actually runs C code and passes your variables to the C code under the hood) In the python source code only 1 place specifies the value can be something non-zero: github.com/python/cpython/blob/main/PC/winreg.c#L1731-L1771 and this is because it's replaced by a zero here github.com/python/cpython/blob/main/PC/winreg.c#L1793 Reading the documentation for RegOpenKeyExW() here: learn.microsoft.com/en-us/windows/win32/api/winreg/nf-winreg-regopenkeyexw#:~:text=%5Bin%5D%20ulOptions,when%20absolutely%20necessary. It states that the value being passed as "reserved" is 0 for a regular link or set to the constant REG_OPTION_OPEN_LINK to make it a symbolic link. (with the warning "Registry symbolic links should only be used when absolutely necessary"). I am not as familiar with the registry, but a symbolic link in general is basically a "file" or "file-like" object that points to another (like a shortcut). It seems like this is the only other possible value, but they don't want you to do this in python (or C) because I would assume like normal symbolic links if the thing you're linking to is deleted, everything linking to it breaks as well! I apologize I couldn't be more precise in my response. As I said this is largely speculative, and my best guess. I would not act on this information until there is something more obvious to confirm this info, but I suspect this is what's happening. For time being, listen to the comments and leave it on 0

Nope, VS Code will use your python install (bottom right corner it will tell you which one it's using). But it only loads the packages you have when you open the editor, so if you install something while VS code is open you need to close it and reopen for the autocompletion to recognize the package.

How so?

Unfortunately not, I have not modified any of this code for a long time after searching for more information for a while
