You need to use a library that does password key derivation, secret key encryption and preferably a message authentication code to verify integrity. For a C++ library with lots of options, try crypto++:
Crypto++ has lots of older algorithms that should no longer be used in modern systems. I recommend Argon2 for password key derivation, and ChaCha20 with Poly1305 for secret key encryption. Kind regards, Philip Bennefall

.csv files are plain text files except that the data is separated with a comma (thus called csv files - comma separated files). Data in Text files cannot be password protected but you can protect the entire file so that nobody can open it without a password. I am not sure if this is what you are asking about. -- With over 2.3 billion devices now running Windows 10/11, customer satisfaction is higher than any previous version of windows.
Yeah I want that entire file can be opened after entering the correct password.
Do we have any function to support this?
