Prior to this commit, authenticity tokens would be either 32 or 64 characters long, depending on the presence of SecureRandom in the environment.
This changes
Rack::Protection::Base#random_string
to always output strings of 32 characters, ensuring that generated authenticity tokens will always have the same length (whether we're usingSecureRandom.hex
