tcaddy / aes-128-ecb.rb

Created March 8, 2017 16:15

Ruby AES-128-ECB encryption / decryption example. This was written to interface with a 3rd party that required string parameters to be encrypted the following way: Rinndael cipher, Electronic Code Block mode (ECB), no padding, encrypted buffer should be padded with spaces such that its length is divisible by 32.

	# setup some input parameters
	encrypted_decrypted = 'some string to encrypt or decrypt'
	action = :encrypt # set to :encrypt or :decrypt
	secret_key = 'abc123' # define shared secret key here

	# encryption / decryption code...
	cipher = OpenSSL::Cipher.new('AES-128-ECB')
	if action == :decrypt
	cipher.key = [secret_key].pack('H*')
	cipher.padding = 0
