Hi Everyone, When I try to execute the code below, I don't get any errors, but the data is never decrypted. I have tried tons of different people's code, but to no avail. Any help would be appreciated. Here is my code: $data= mcrypt_ecb(MCRYPT_TripleDES, $key, $data, ENCRYPT); echo "data: $data"; $data= mcrypt_ecb(MCRYPT_TripleDES, $key, $data, DECRYPT); echo "data: $data"; And here is the output: Warning: attempt to use an empty IV, which is NOT recommend in ../../includes/scripts/admin_functions.inc on line 52 data is: áyp)l)©>¤IÔNþ&ñ¸«Ø¼{j<{’Â]Ƹ«Ø¼{j<{’Â]Ƹ«Ø¼{j<{’ Â]Ƹ«Ø¼{j<{’Â]Ƹ«Ø¼{j<{’Â]Ƹ«Ø¼{j<{’Â]Æ—¶µßÛKš á×½ÄeDÜ Warning: attempt to use an empty IV, which is NOT recommend in ../../includes/scripts/admin_functions.inc on line 55 data is: ©’WYbdù’ 8žÊSQÝ›z-A|úyÕ»å™u$F›z-A|úyÕ»å™u$F›z-A|úyÕ»å™u$F›z-A|úyÕ»å™u$F›z-A|ú yÕ»å™u$F›z-A|úyÕ»å™u$FÇVæˆËúMŒËÞ•=ÛÚ Even when I try to use an IV, it still doesn't ever decrypt, or sometimes it will give me an error about the key being too long.
