Question:

I wanted to know if I can decrypt this image that uses AES ECBand CBC In PYTHON. The ECB Method is used in below code, but i wanta decryption method for cbc also. Please make sure the sameencryption is used. please provide a working code for thedecryption part. Code used for encryption is (Code done in visualstudios)

filename = "image.jpg"

filename_out = "EncryptedAES"

key = "aaaabbbbccccdddd"

def pad(data):

return data + b"x00"*(16-len(data)%16)

def convertRGB(data):

r, g, b = tuple(map(lambda d: [data[i] for i inrange(0,len(data)) if i%3==d], [0,1,2]))

pixels = tuple(zip(r,g,b))

return pixels

def process_image(filename):

im = Image.open(filename)

data = im.convert("RGB").tobytes()

original = len(data)

new = convertRGB(aes_ecb_encrypt(key, pad(data))[:original])

im2 = Image.new(im.mode, im.size)

im2.putdata(new)

im2.save(filename_out+"."+"png", "png")

def aes_ecb_encrypt(key, data, mode=AES.MODE_ECB):

IV = "A"*16

aes = AES.new(key.encode('utf-8'), mode)

new_data = aes.encrypt(data)

return new_data

process_image(filename)

When I put the command process_image('imagefilename.jpg'), i getan encrypted form of image with AES. I need the decryption processfor this method. This code directly works to produce an AESencrypted output
