how to combine the addon with ofxCsv when loading a file?

[moebiussurfing]

My idea is to hide a csv file (previously encrypted outside OF) when using my app on an installation.

Now I am reading a plain csv file with ofxCsv (https://github.com/paulvollmer/ofxCsv
) and I would like to know how to start to try to do this:

I want to combine both plugins, and to modify ofxCsv (with ofxCrypto) to read the csv encrypted file, decode and read the rows/columns.
but I don't know how to manage ofBuffers and ofFile yet...
any help is appreciated.
