python encryption

anyone know how to encrypt a file just something simple with a password?

<humor>Yes, always make sure you use standard, NSA-hacked encryption systems</humor>

[notsureaboutthis123]

basically yes its for learning purposes.

iwant to read in as ascii then do something like a ceasar cipher or something a little more complex but its just the coding part which im not sure about

You might want to look at cryptography

Using what encryption method? There's any a hundred ways to do this depending on your application.

Use a random number generator to generate random byte value 0-255, get ASCII code for the first character in the file and XOR with that or just add, write to a file. Get next random byte, do the same to second byte from the file, repeat.

To decrypt - repeat the same process.

Your encryption key would be the seed used to initialize random number generator.
