oslopolicy-checker demo

This document describes how you can get the right information to effectively use oslopolicy-checker. The tool requires a token which is evaluated by the oslo.policy enforcer object. You can do this easily by exporting a cloud profile and using python-openstackclient.

Shapes

You need to use structs to model triangles and squares. Your module should have a printArea() that takes a shape as a receiver. The printArea() function should call an interface (e.g., getArea) that is implemented by your shapes and contains the implementation for calculating the area for those shapes. Shapes cannot have negative values.

Tests

Simple Public Key Cryptography Examples

I was following the examples in a post but rewrote the mathematical terminology so that it read a little bit easier.

RSA Example

A simple RSA example showing how to generate a public and private key pair for asymmetric encryption.
