I have a text of about 800 characters, about 5 paragraphs. When I go to encrypt it encrypts the text with no problem, the problem is to decode the text, approximately decrypts the first 60 characters with no problems, the rest is not decoded.

I appreciate your cooperation with this matter.

Agradezco su colaboración con este tema.

There's a bug in the AES.class.php functions
stringToHex() and hexToString()

I'm sending the updated AES.class.php code to the class author.

Apparently the changes haven't been released yet. How do you fix it?

you fix it by using phpseclib's implementation:

as noted in another post, it's significantly better than this one:

Can you please point me to the function that should be used to replace hexToString?

Thanks.
