Thank you for the response Dave,
I’ve just changed it to
$ret = base64_encode(hash_hmac(“sha1″, $s1.$abyte0, $abyte0,true));
and am now getting a 28 character code for $ret
Cheers

Barry

Hi Barry,

I’m not sure if that will give you the same value – I’ve tried your code on a box that has MHASH with some dummy values and they don’t appear to be giving out the same value. It might be worth looking for an alternative PHP function to generate the hash.

Hello

Would this class work with
$ret = base64_encode(hash_hmac(“sha1″, $s1.$abyte0, $abyte0));

instead of
$ret = base64_encode(mhash(MHASH_SHA1, $s1.$abyte0, $abyte0));

as my hosting doesn’t have mhash function working.

I’ve tried it but I ‘m getting error 10 -” The transaction failed because of invalid input data.” but I’m not sure if this is the hash or not. ANyhelp would be much appreaciated.
Cheers

Barry
