From: gm dot outside+php at gmail dot com Operating system: Linux PHP version: 5.6.1 Package: Testing related Bug Type: Bug Bug description:mcrypt_encode tests are broken
Description: ------------ There was a recent commit (http://git.php.net/?p=php-src.git;a=commit;h=a861a3a93d89a50ce58e1ab1abef1eb501f97483) that changed behaviour of the mcrypt_encode() function. After that commit the key is required to be at least the expected key length long, otherwise a warning message is issued and the mcrypt_encode() routine returns a failure. The corresponding test in ext/mcrypt/tests/bug62102_rfc2144.php supplies 10 bytes key instead of 16 for cast-128 80-bit encryption and 5 bytes key instead of 10 for cast-128 40-bit encryption. A quick fix to the test would be to pad the keys with '\0' manually (RFC-2144 B.1), e.g. mcrypt_encrypt('cast-128', "\x01\x23\x45\x67\x12\x34\x56\x78\x23\x45\0\0\0\0\0\0", $plaintext, 'ecb') but unfortunately due to the way changed code treats key data (as a null terminated string) and due to calculating the key size as strlen() of that string there is no way to satisfy the RFC-2144 B.1 since all trailing '\0' will be ignored. Expected result: ---------------- That the RFC-2144 test would be passed with the explicitly specified vector and that mcrypt_encrypt() would honour the key argument as a binary string that can include '\0' anywhere in the string. Actual result: -------------- All trailing '\0' in the key argument are ignored, therefore it's impossible to pass RFC-2144 test to match section B.1. -- Edit bug report at https://bugs.php.net/bug.php?id=68238&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68238&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68238&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68238&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68238&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68238&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68238&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68238&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68238&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68238&r=support Expected behavior: https://bugs.php.net/fix.php?id=68238&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68238&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68238&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68238&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68238&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68238&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68238&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68238&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68238&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68238&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68238&r=mysqlcfg -- PHP Quality Assurance Mailing List <http://www.php.net/> To unsubscribe, visit: http://www.php.net/unsub.php
