using joomla (or even just PHP), how would you obfuscate a PDF filename? -

i have file, phone call secret.pdf, offer download. however, maintain having url can copied / pasted or typed out www.website.com/pdf/secret.pdf (no fishing files!).

for instance, user clicks on link, , gets kgsjgldsg.pdf. user b clicks same link, gets asadsfsefaw.pdf. point is, random filename used reference same file, secret.pdf.

ive googled php file obfuscator, , joomla filename obfuscator, , have had no luck. ideas or pointer in right direction much appreciated.

you add together get variable based on time, valid 1 min (should enough).

so request /pdf/getpdf.php?key=xxxxxxxxx

make key salted hash based on current time on server, instance closest number dividable 5 (when it's 17:17 you'd utilize 17:15, etc).

then generations 'current' hash on getpdf.php file, , if same, stream pdf.

this not stop people using link, link valid 5 minutes.

addendum: should create sure pdf not reachable outside, readable pdf-streaming php-file (e.g. outside /var/www or equivalent directory)

php joomla

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? -

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? - what difference between "some" == "some\0" , strcmp("some","some\0") in c++? why if("some" == "some\0") returns false , if(!strcmp("some","some\0")) returns true ? see next diagram. shows 2 strings in memory, content in box, beside box you'll see address of each one. when you're doing if("some" == "some\0") comparing addresses. translated if (0xdeadbeef == 0x0badcafe) false. when utilize strcmp , compare content of each box until reach \0 in each of them. that's why sec test returns true. if alter first test if("some" == "some") compiler may potentially see same strings , store them once. means test transform if (0x0badcafe == 0x0badcafe) true. c++ string comparison

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? -

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? - i have follow issue : i have point setted @ border on component, changed transform point center of component in order match component rotation. the of import part when seek point xy after rotation - remains same before rotation. how xy, after rotation ( changeing point.rotation property specific degrees of rotaion ) if want point after rotation, cos(r) * x, sin(r) * y easiest way. if want point after transformations, should able utilize displayobject.transform.transformpoint(x, y) . there's displayobject.localtoglobal . in case phone call localtoglobal(x, y) , localtoglobal(0, 0) , calculate difference. see transform livedocs , displayobject livedocs flex actionscript-3
