No solutions found from searching web. Using latest libmcrypt.dll and all permissions set correctly. If the mcrypt_decrypt line is // out then it will complete but only do the encrypt. Any ideas? Reproduce code: --------------- $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB); $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); $key = "This is a key"; $text = "This is a test string."; echo strlen($text) . "<br>"; echo $text."<br>"; $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $text, MCRYPT_MODE_ECB, $iv); echo strlen($crypttext) . "<br>"; echo $crypttext."<br>"; $decrypttext = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key, $crypttext, MCRYPT_MODE_ECB, $iv); echo strlen($decrypttext) . "<br>"; echo $decrypttext."<br>"; Expected result: ---------------- Should DeCrypt String Actual result: -------------- PHP has encountered an Access Violation at 6C1994EB42 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27118&edit=1
