WIP: Ruby AES Encryption using AES-256-CBC

	require 'openssl'

	# We use the AES 256 bit cipher-block chaining symetric encryption.
	# AES 256 is virtually impenetrable using brute-force methods.
	# However, CBC introduces a data integrity vulnerability (stream cipher attacks).
	# We should use HMAC or GCM to mitigate the issue.
	alg = 'aes-256-cbc'
	cipher = OpenSSL::Cipher::Cipher.new(alg)
	cipher.decrypt
