Apex Crypto class have "generateDigest()" method which converts the given String to the Digest according to the given algorithm(MD5 etc). It does not implement the Http Digest Authentication cycle. Different languages provides native support fro Http Digest Authentication, which implements RFC2617. Does Apex have native support for the HTTP Digest Authentication? Or any other alternate to use Http Digest Authentication in Apex code?

HI,
   i am acessing an external webservice using apex class. My external webserices is restful webservice and it uses Digest access authentication. I am acessing it in java and its working fine. I need to access it using apex code. Here is my apex code...


HttpRequest req = new HttpRequest();
req.setEndpoint(serviceEndPoint);
req.setMethod('POST');

req.setBody(xmlFeed);

String myDeveloperAPIKey = 'xxxx';
String username = myDeveloperAPIKey + '%xxxxxuserName';
String password = 'xxxPassword';


Blob headerValue = Crypto.generateDigest('MD5', Blob.valueOf('username:password'));

String authorizationHeader = EncodingUtil.convertToHex(headerValue );

req.setHeader('Authorization',authorizationHeader );
req.setHeader('charset', 'UTF-8');     
req.setHeader('Content-Type', 'application/atom+xml');

Http http = new Http();
HTTPResponse res = http.send(req);

return 'status=' + res.getStatus();



It is returning Status="unAuthorized", where as userName/Pasword/key are all correct. can anybody figure out whats wrong here? or what is missing?...
