Encrypting in Python

Question

I tried using the "pycryptodome" module and i got this error: "not a valid pem post boundary"
i saw someone that wrote to use another module so i tried "cryptography" and it was too coplicated!
now im trying the "rsa" module and there is no documentation and not many features.
all i want is to be able to generate a private key, save it into a file, extract it from the file, be able to generate a public key from the private key, be able to convert it to str format and back to the key format and encrypt/decrypt using the keys. thats all i need.
can someone help me?

I think you need to create a database for the server program but because it is in a localhost network you can only use os module to open a file that contains list or dictionary of ligitimate clients then check if the client name/Id/name/ that send message to the server exists in the file then accept the connection.
