SHA versions supported by OpenSAML and CXF can be specified in saml.properties in the CONNECT properties directory. Note that while multiple versions can be specified, a default must also be specified and can be overridden in the entity request (described in Overriding default SHA version section below). Make sure the properties include backslash after common.  Please see sample entries in saml.properties

Once a list of allowable SHA versions and a default has been specified, a specific version from the allowable list can be specified in the entity request. An example algorithm override follows:
