Access Code Example

What?

This demonstrates an example implementation of the concept of access codes, with the following invariants:

• Access codes are case-insensitive ("ABC", "abc", "AbC", and "abC" are equivalent)
• Access codes are not equal if the values are blank / empty / nil ("\n", "", " ", and nil are not equivalent to each other or themselves)
• Access codes should not be susceptible to [timing attacks] when values are compared

Running the Tests

rspec access_code.rb
