#44133 [NEW]: Encrypting then decrypting a string results in unidentical strings.

From: squinky86 at gmail dot com Operating system: Linux and Windows PHP version: 5.2.5 PHP Bug Type: mcrypt related Bug description: Encrypting then decrypting a string results in unidentical strings. Description: ------------ When I mcrypt_encrypt() a string, then immediately mcrypt_decrypt() the string, the result is two strings that appear identical but are not. Reproduce code: --------------- Due to having multiple test cases for this bug, I have posted the code to: http://www.phpfreaks.com/forums/index.php/topic,182537.msg815864.html Note also that since the posting of this issue, I have noted the following: strlen($toEncrypt) == strlen($decrypted) == 13 ord($toEncrypt[$i]) == ord($decrypted[$i]) for all $i = 0..12 For all intensive purposes, the strings are identical, but PHP does not define them as such. Expected result: ---------------- The strings should be identical after encryption and decryption Actual result: -------------- The strcmp() function returns "-3". The == operator returns "false". -- Edit bug report at http://bugs.php.net/?id=44133&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=44133&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44133&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44133&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44133&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44133&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44133&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44133&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44133&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44133&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44133&r=support Expected behavior: http://bugs.php.net/fix.php?id=44133&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44133&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44133&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44133&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=44133&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=44133&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44133&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44133&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44133&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44133&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44133&r=mysqlcfg
