Hello software developers,

Please check your code to ensure you're not making one of the following mistakes related to cryptography.

I. General Mistakes

Writing your own home-grown cryptography primitives (For example: Mifare Classic)
- Exception: For the sake of learning, but don't deploy it in production.
Using a fast hash function (e.g. MD5, SHA256) for storing passwords. Use bcrypt instead.
Not using a cryptographically secure random number generator

For an ADT type, such as,

data Exp = Num Int | App Char Exp
  deriving (Show)

In Haskell we have case expressions to deconstruct values, and they have exhaustiveness checking. We have

	# Wouldn't it be great if you could have STI like functionality
	# without needing to encode strings of class names in the database?
	# Well today is your lucky day! Discriminable Model is here to help.
	#
	# Simply specify your models desired type column, and provide a block to
	# do the discrimination. If you want the whole STI-esque shebang of properly
	# typed finder methods you can supply an array of 'discriminate_types' that will
	# be used to apply an appropriate type.
	#
	# class MyModel < ActiveRecord::Base
