Example Code

   require 'openssl'

   cipher = OpenSSL::Cipher::Cipher.new( "des-ecb" )
   cipher.encrypt
   cipher.key = key_to_use
   cipher.iv = iv_to_use

   output = cipher.update( data_to_encrypt )
   output << cipher.update( more_data_to_encrypt )
   output << cipher.final

   cipher = OpenSSL::Cipher::Cipher.new( "des-ecb" )
   cipher.decrypt
   cipher.key = key_to_use
   cipher.iv = iv_to_use

   output = cipher.update( data_to_dencrypt )
   output << cipher.update( more_data_to_dencrypt )
   output << cipher.final
