Hi,
I think from RJ256 encryption, you mean Rijndael encryption?
After an extensive search I got one from google and stackoverflow and make it working.
It is originally written by Bram Cohen. Code is clear and concise.
I checked it with online Rijndael encryption tools, and it is working perfectly. and can perfectly
decrypt, PHP encrypted value.
PM me, I will send you the code and possibly some screenshots, if you find it useful then take it and give the $20.
I found some other alternative versions, PM me we will discuss it.
Thanks
Mahan Marwat
