ENCRYPT/DECRYPT jpg file online

Hello flatassamblers Rolling Eyes

Im making a image encoder/decoder app with ASM.First i must write how it works:
1.I use wininet for READING a .JPG or .BMP or .ANYTHING from example.com/IMAGE.ANYTHING and store it inside variable cwhich work perfect but what i need and i failing since last week is use AES for encrypt that image and decrypt it from my FASM program ---example/IMG.BMP--*read bytes*--- then decrypt that bytes.Can someone help me With encoding and decoding ? Here is AES which work perfect with static string

Code:

format PE CONSOLE 4.0
entry start

include 'INCLUDE/win32a.inc'
include 'aes/aes.inc'

TEXTSIZE equ 3*BLOCK_SIZE

section '.text' code readable executable

  start:
   ; stdcall encAES, TEXTSIZE, clear_msg, enc_msg, key128
   ; stdcall decAES, TEXTSIZE, enc_msg, dec_msg, key128

    ;stdcall encAES, TEXTSIZE, clear_msg, enc_msg, key192
    ;stdcall decAES, TEXTSIZE, enc_msg, dec_msg, key192

    stdcall encAES, TEXTSIZE, clear_msg, enc_msg, key256
    ;stdcall decAES, TEXTSIZE, enc_msg, dec_msg, key256
     push enc_msg
     call [printf]

    invoke getchar

How to i can use this for encrypt my variable readBytes dd ? and save it on disk as binary file encoded.anything and how to i can decrypt readBytes dd ? ? Or simplz written how i can use this AES on dd variable not db? thx pleas i need help[/b]
