How to consume Web Service with Password digest from PLSQL

Question

We have Oracle 10g (10.2.0.3.0) 64 bit. We have a situation where we need to consume web service whose security header looks like as follow,
<soapenv:Header>
<wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
<wsse:UsernameToken wsu:Id="UsernameToken-50">
<wsse:Username>weblogic</wsse:Username>
<wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">d2enK45chjBPVvvukbYU6OX56kI=</wsse:Password>
<wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">YAhEtLJfp4lzycLd3hZYjQ==</wsse:Nonce>
<wsu:Created>2013-01-22T06:28:38.897Z</wsu:Created>
</wsse:UsernameToken>
</wsse:Security>
</soapenv:Header>
Here we need passowrd digest, Nonce and Timestamp.
How to create password digest from PLSQL? or if any other alternatives available please response soon.

Answer 1

I do not see why it will not be possible to do digest authentication with a web server using PL/SQL.
As for the digest password - the web server supplies a token (a nonce) which you need to use for creating the hashed authentication token (the digest password). The URL I posted explains this authentication process.
As for the technical how-to in PL/SQL - as I mentioned, never had to do this (only dealt with Basic and NTLM authentication thus far). But as other auth methods (such as Microsoft's NTLM) can be implemented, I do not see why digest authentication could not.
Suggest you spend some time googling for technical articles/sample code on the subject - and try to find specific PL/SQL related sample code too.
