Hi,
I am experiencing this problem also. When I run mcrypt_decrypt it
causes apache to crash. However, mcrypt_encrypt is working fine.
I have Mcrypt module loaded as a dynamic module on apache. I am using
Windows XP professional, apache 1.3 and php 4.3.4 . The mcrypt dll
library is a "libmcrypt + php 4.3.x on windows".
The following is the example code I used, which causes apache to
crash.
If you any questions or suggestions please do not hesitate to contact
me. Thanks in advance.
Cheers,
Daniel
==================================
Example code
================================
example6_encrypt();
function example6_encrypt(){
$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);
$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
$key = "This is a very secret key";
$text = "Meet me at 11 o'clock behind the monument.";
//echo strlen($text) . "\n";
$crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $text,
MCRYPT_MODE_ECB, $iv);
//echo strlen($crypttext) . "\n";
echo "<p>encrypted string: <b>$crypttext</b></p>";
example6_decrypt($crypttext);
}
/*
string mcrypt_decrypt ( string cipher, string key, string data, string
mode [, string iv])
*/
function example6_decrypt($text){
$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB);
$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
$key = "This is a very secret key";
$decrypt_text = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key, $text,
MCRYPT_MODE_ECB, $iv);
echo "<p>decrypted string: <b>$decrypt_text</b></p>";
}
