- Extends upon the CTR mode by allowing for the user to provide an index of a block they want to encrypt/decrypt. - Add function AES_CTR_xcrypt_block_at_position(). - Add function AES_CTR_xcrypt_block_at_position_extended(). - Should produce exactly the same output as CTR mode when used sequentially.
