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.
