From: yu at csh dot dp dot ua Operating system: Windows 2000 PHP version: 4.3.4 PHP Bug Type: mcrypt related Bug description: mdecrypt_generic() doesn't decrypt anything
Description: ------------ Server is localhost. Function mdecrypt_generic() doesn't decrypt anything. Instead it returns value of the encrypted string without changing. Crypt-library loaded from http://ftp.emini.dk/pub/php/win32/mcrypt/libmcrypt.dll , as specified in the php_manual for mcrypt functions. Same problem reports other users: http://bugs.php.net/bug.php?id=3165&edit=2 - Bug #3165: encrypt/decrypt not a function? http://www.forbiddenweb.org/viewtopic.php?t=4556 here is another link to crypt-libraries, that point as functional: http://ftp.proventum.net/pub/php/win32/misc/mcrypt/ , but i don't check it functionality. Additionaly mcrypt_create_iv() produces same iv for every time script is runing. But this not problem when, for example, <? ... $iv=substr(pack('h*',sha1(uniqid(rand())), 0, mcrypt_enc_get_iv_size($td)); ... ?> Reproduce code: --------------- <?php #Example to mcrypt_module_open() from php_manual_ru.html #almost without changes srand(); $td = mcrypt_module_open('rijndael-256', '', 'cbc', ''); $iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), MCRYPT_RAND); $ks = mcrypt_enc_get_key_size($td); $key = substr(md5('very secret key'), 0, $ks); mcrypt_generic_init($td, $key, $iv); $encrypted = mcrypt_generic($td, 'This is my data'); mcrypt_generic_deinit($td); mcrypt_generic_init($td, $key, $iv); $decrypted = mdecrypt_generic($td, $encrypted); mcrypt_generic_deinit($td); mcrypt_module_close($td); echo trim($decrypted) . "\n";?> Expected result: ---------------- "This is my data" Actual result: -------------- $encrypted value -- Edit bug report at http://bugs.php.net/?id=27062&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=27062&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=27062&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=27062&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=27062&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=27062&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=27062&r=needscript Try newer version: http://bugs.php.net/fix.php?id=27062&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=27062&r=support Expected behavior: http://bugs.php.net/fix.php?id=27062&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=27062&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=27062&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=27062&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=27062&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=27062&r=dst IIS Stability: http://bugs.php.net/fix.php?id=27062&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=27062&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=27062&r=float
