I'm stuck on one issue. I've used the form sent out via comment emails as a basis, but I'm having a hard time generating the ECP hash.
In talklib.pl, the hash is generated like so:
sub ecphash {
my ($itemid, $talkid, $password) = @_;
return "ecph-" . Digest::MD5::md5_hex($itemid . $talkid . $password);
}
In PHP, I'm doing this:
$TalkID = '1010';
$ItemID = '010101';
$Password = 'mypassword';
$ECPHash = md5($ItemID . $TalkID . $Password);
However, the submitted form is rejecting the hash as having the wrong password. Is there some further munging of the password that needs to be done to generate a valid password for hashing? Or is the PHP md5() doing something different than the Perl library?
Now, I know the TalkID and the ItemID aren't the problem, which leaves me with one of two options:
1) The MD5 hashing functions work differently between PHP and Perl (which would be odd).
2) The password being used to generate the hash on LJ's side is not a clear-text password, but rather some sort of encrypted form of the password being pulled from their database
Any clues?
Edited To Add: Thank you,
soph! Here is the fixed and working code:
$Journal = 'JournalReceivingReply';
$Poster = 'UsernameOfReplyingParty';
$TalkID = '01010';
$DItemID = '101010';
$JItemID = intval($DItemID/256);
$Password = 'apassword';
$ECPHash = md5($JItemID . $TalkID . $Password);
echo '
