RSA encyption of files

I am new to encryption, and am trying a determine how to encrypt a
file using RSA encryption in perl. The module Crypt::RSA only allows for
encryption of strings rather than a whole file.

Are there any modules which can do the job?

Here's what I know so far: You have a C++ project. You have source files in it. When you go to compile it, first thing the preprocessor sticks the header files into each source file. So now you have your ".cpp" files all ready, without any "#include" or "#define" in them. Let's assume that there's 2 source files in this project, "a.cpp" and

If there any way to password protect the...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
