[PHP] hash_hmac: Encoding with two different results problem

2008-07-24 Thread Leon du Plessis 
hi,
I hope this is the right group for this type of problem:

I am using hash_hmac to provide me with a sha1 encoded hash string. The 
problem is as follows:

$hash = hash_hmac('sha1', 
'030B6A05696E657400C54601C60001550187360603773500018707060373796E63000187340603687474703A2F2F772E73796E632E636F6D2F73796E630001C65901873A06032E2F636F6E7461637473000187070603436F6E74616374732044420001872E0603746578742F782D7663617264000101C6570187310603757365726E616D6500018732060370617373776F72640001010101',
 
'1234');

Note: it is important the key to use during encoding id 1234 for this 
example.

Result:
eb38ffd597c6d1e01cd24a0e46dff426354510fe

Using a hash calculator from slavasoft also yields this result, which 
indicate the encoding is fine.
eb38ffd597c6d1e01cd24a0e46dff426354510fe

However, Slavasoft's calculator has an option to provide the string as Text 
or Hex.

Selecting hex yields this result:
9f9be99ea5bf5ba009af0a5c12021f420cb27652  and this is the string I 
need!!!

So either hash_hmac function needs a way to let it know the string is of 
type hexor the string itself needs to be converted. I have tried some 
conversions on the string but to no avail.
Anyone have any thoughts?

gotchu covered ;)

found this on the web:

http://www.pgregg.com/projects/php/code/hexstr.phps

so then,

?php

function hexstr($hexstr) {
  $hexstr = str_replace(' ', '', $hexstr);
  $retstr = pack('H*', $hexstr);
  return $retstr;
}

$hash = hash_hmac('sha1', hexstr(
'030B6A05696E657400C54601C60001550187360603773500018707060373796E63000187340603687474703A2F2F772E73796E632E636F6D2F73796E630001C65901873A06032E2F636F6E7461637473000187070603436F6E74616374732044420001872E0603746578742F782D7663617264000101C6570187310603757365726E616D6500018732060370617373776F72640001010101'),
'1234');

echo $hash;
