Hi,
trying to use mcrypt/decrypt, but i'm not able to print the decoded text without the script stopping.
The code below is taken from php.net, supplied by jon@jonroig dot com 07-Apr-2004 07:29.
<?
$key = "this is a secret key";
$input = "Let us meet at 9 o'clock at the secret place.";
$td = mcrypt_module_open('tripledes', '', 'ecb', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND);
mcrypt_generic_init($td, $key, $iv);
$encrypted_data = mcrypt_generic($td, $input);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
echo "Encrypt: ".$encrypted_data;
echo "<br><br>";
$td = mcrypt_module_open('tripledes', '', 'ecb', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND);
$key = substr($key, 0, mcrypt_enc_get_key_size($td));
mcrypt_generic_init($td, $key, $iv);
$decrypted_data = mdecrypt_generic($td, $encrypted_data);
echo "Decrypt: ".$decrypted_data;
//modified
echo "something's wrong";
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
?>
The script seems to work, but the string "something's wrong" doesn't print.
However the script below works fine:
<?
$key = "this is a secret key";
$input = "Let us meet at 9 o'clock at the secret place.";
$td = mcrypt_module_open('tripledes', '', 'ecb', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND);
mcrypt_generic_init($td, $key, $iv);
$encrypted_data = mcrypt_generic($td, $input);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
echo "Encrypt: ".$encrypted_data;
echo "<br><br>";
$td = mcrypt_module_open('tripledes', '', 'ecb', '');
$iv = mcrypt_create_iv (mcrypt_enc_get_iv_size($td), MCRYPT_RAND);
$key = substr($key, 0, mcrypt_enc_get_key_size($td));
mcrypt_generic_init($td, $key, $iv);
$decrypted_data = mdecrypt_generic($td, $encrypted_data);
//echo "Decrypt: ".$decrypted_data;
echo "something's wrong<br>";
echo "something else is wrong";
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
?>
Outputs:
Encrypt: \ºþê?Ï? áž(v¹FýaõFËU³æç SäÇÚÖz ßù5Qì<±_?-:Í
something's wrong
something else is wrong
