Hello I have been trying to make simple encryption with AES128 between app in C# and PHP, and it worked well quite well yesterday. I got like max 10% unencrypted data but now I got a maybe 90% unencrypted/unencoded/incomplete data. I am sure its because of the "special" charactes in these strings. I am sure it breaks the string into more strings and then it reads just part of it for example this
"/" or "+"
seems to break it every time and I cant remove these characters because it will break everything. I have tried something like this
$test = base64_decode(addslashes($StringEncodedBase64));
in hopes that it will hold the string together but I think it didnt help much if at all. I think only improvement was yesterday when I had The string encoded with base64 maybe 3-4 times atleast basically every step ended with base64 encode so i would get a nice hash in the end. But I dont want that because its nonsense performance wise pretty much and there is still some % data lost and more importantly I think it was because I used a weak key. Maybe yesterday when I was testing it I had better success ratio because I had very simple key like
1234567890123456
I have changed the key and the new is more complicated like
Omb1AH02AsuUACfu
is it why it produces these complicated broken strings? For IV I use random strings without numbers like
IHZWGhoxZoIugQmY
In the end of this logfile is one luckily decrypted message. On the lines above are the other 90%. I also thought about converting the these special characters into byte[] but the mcrypt_decrypt want a string and I also need it to return me a string after all. Thanks for any input
