I have already implemented encryption / decryption between php and android using AES / CBC.
However, when I decrypt the images using an Android phone, for a 300k file it will always take more than 1 second. How to speed up decryption? Thank you very much!
PS: I use mCrypt extensionto encrypt php and javax.crypto.Cipherto decrypt android. I mean, can I use another cryto mode or another mode?
