Binary security token

The <ValueType> attribute identifies the type of the security token, for example, a LTPA token. The EncodingType indicates how the security token is encoded, for example, Base64Binary. The <BinarySecurityToken> element defines a security token that is binary encoded. The encoding is specified using the EncodingType attribute. The value type and space are specified using the ValueType attribute. The WS-Security implementation for WAS, V 5.0.2 supports both LTPA and X.509 certificate binary security tokens.

There is an important distinction between V5.x and Version 6 and later applications. The information in this article supports Version 5.x applications only that are used with WAS V6.0.x and later. The information does not apply to V 6 and later applications.

A binary security token has the following attributes that are used for interpretation:

• Value type

• Encoding type

The following example depicts an LTPA binary security token in a Web services security message header:

<wsse:BinarySecurityToken 
    xmlns:ns7902342339871340177=
                      "http://www.ibm.com/websphere/appserver/tokentype/5.0.2"
     EncodingType="wsse:Base64Binary"
     ValueType="ns7902342339871340177:LTPA">

</wsse:BinarySecurityToken></wsse:Security></soapenv:Header>

As shown in the example, the token is Base64Binary encoded.
