This should be described in the documentation of the soap service you're using.

If it is sha1 and you're using php, then sha1('something here') should do it.

Thanks a lot Brother.

But i have already use sha1.....but facing error.
[faultstring] => Hash values do not match. (from client)

i have also referance site like :
http://www.cryptosys.net/pki/xmldsig-ChileSII.html#creatingxmldsig

But i cann't generate my Signature Value and facing error......Hash Values do not match..plz help me

You should have a look at the demos on that page. sha1() is not enough, you need to canonicalize the data as described.

you are right brother........

$dom = new DOMDocument();
$dom->loadXML($myXMLData);
$canonicalized = $dom->C14N(); // for the whole document

$ssDigest = base64_encode(pack("H*", sha1($canonicalized)));

from above code we easily get a DigestValue...and i have read in somewhere....encrypt of Digestvalue is SignatureValue.

i try manytimes but not get a solution....

how to get SignatureValue from DigestValue ??
