Implementation of image file security using the advanced encryption standard method

The application of technology in this era has entered digitalization and is modern. Therefore, we are already an advanced rapid technological development. It become a human need to exchange information every activity. Documents that contain frequently sought or used. document's use also includes essential information. Document security undoubtedly significant factor prioritizing important document prevent unauthorized people from misusing the vital Cryptography method overcoming issues so third parties cannot read messages contained within document. 128-bit encryption standard (AES) algorithm one algorithms included cryptography technique. Additionally, it can be combined with operation modes such as electronic codebook (ECB) cipher block chaining (CBC) create generate random codes improve data
