note 69174 added to function.md5

I agree with Thomas about the note of "endeveit at pisem dot net". Decreasing the size of a hash simply make is less secure, no matter what the system of reducing is. The ultimate measure is the total possible results. An integer with 8 bytes has less number of possibilities than a normal hash value. ---- Server IP: 139.179.10.17 Probable Submitter: 212.50.35.98 (proxied: 1.1 BMISA) ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.md5.php Edit -- https://master.php.net/note/edit/69174 Del: integrated -- https://master.php.net/note/delete/69174/integrated Del: useless -- https://master.php.net/note/delete/69174/useless Del: bad code -- https://master.php.net/note/delete/69174/bad+code Del: spam -- https://master.php.net/note/delete/69174/spam Del: non-english -- https://master.php.net/note/delete/69174/non-english Del: in docs -- https://master.php.net/note/delete/69174/in+docs Del: other reasons-- https://master.php.net/note/delete/69174 Reject -- https://master.php.net/note/reject/69174 Search -- https://master.php.net/manage/user-notes.php
