How to create Password Digest for use with Web Service?

Question

I am trying to create a passwordDigest util which can be used in different environments which are capable of running java byte code.

First of all I create nonce. It is done like so.

public static String buildNonce(){
        StringBuffer nonce=new StringBuffer();
        String dateTimeString = Long.toString(new Date().getTime());
        byte[] nonceByte= dateTimeString.getBytes();
        return Base64.encode(nonceByte);
    }

Once I have nonce, I build password digest.

public static String buildPasswordDigest(String userName, String password, String nonce, String dateTime){
    MessageDigest sha1;
    String passwordDigest=null;
    try {
        sha1= MessageDigest.getInstance("SHA-1");
        byte[] hash = MessageDigest.getInstance("SHA-1").digest(password.getBytes("UTF-8"));
        sha1.update(nonce.getBytes("UTF-8"));
        sha1.update(dateTime.getBytes("UTF-8"));
        passwordDigest = new String(Base64.encode(sha1.digest(hash)));
        sha1.reset();
    } catch (NoSuchAlgorithmException | UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return passwordDigest;

In order to test that everything works correctly. I have created a test web service using CXF 2.7. I have manually created SOAP Envelope to test authentication. The envelope looks like this.

 <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
                xmlns:ws="http://ws.mytest.org/" 
                xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance/">
    <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-2">
            <wsse:Username>TEST_USER</wsse:Username>
            <wsse:Password 
            Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">UZsDSW/vANu6fHg4rAHo2OwsF9s=</wsse:Password
            <wsse:Nonce>MTQwMTMwMDQzNjA3OA==</wsse:Nonce>
            <wsu:Created>2014-05-28T18:07:16.087Z</wsu:Created>
         </wsse:UsernameToken>
        </wsse:Security>
    </soapenv:Header>
    <soapenv:Body>
        <ws:record>
            <val1>1</val1>
            <val2>Some Text</val2>
        </ws:record>
    </soapenv:Body>
</soapenv:Envelope>

When I send the envelope using SOAP UI. I get the following authentication error.

I suspect that I have an issue creating either nonce or password.

Your help is appreciated.

WS-Security defines password digest as

Base64 ( SHA1 ( nonce + created + password ) )

not

Base64 ( SHA1 ( password + nonce + created) )

And nonce is supposed to be 128 bits (16 bytes) encoded as Base64. e.g.

java.security.SecureRandom random = java.security.SecureRandom.getInstance("SHA1PRNG");
random.setSeed(System.currentTimeMillis()); 
byte[] nonceBytes = new byte[16]; 
random.nextBytes(nonceBytes); 
String nonce = new String(org.apache.commons.codec.binary.Base64.encodeBase64(nonceBytes), "UTF-8");
