i encrypted gif image simple aes algo. got final result algo in hexa number. didn't understand know in gif image has number of frame, there no use of frames in aes algo means did right result. can use result embedding?
aes algorithms - in mode - designed encrypt binary data. output binary data well, although implementation may choose convert format. gif multi-layer of no consequence aes algorithm - long fed binary data encrypt.
decryption works same way. unless taking gif apart, entire image encrypted/decrypted - including layers.
steganography hiding data in - instance - image. not same performing aes block cipher. cannot encrypt image , include - encrypted image random data - if try , read gif format random data gif parsing fail.
