Allow PORTAL_AUTH to use a different digest than MD5

To change the digest algorithm used by PORTAL_AUTH, use a contribution like: <require> org.nuxeo.ecm.platform.ui.web.auth.WebEngineConfig </require> <require> org.nuxeo.ecm.platform.login.Portal </require> <extension target= "org.nuxeo.ecm.platform.ui.web.auth.service.PluggableAuthenticationService" point= "authenticators" > <authenticationPlugin name= "PORTAL_AUTH" > <loginModulePlugin> Trusting_LM </loginModulePlugin> <parameters> <parameter name= "secret" > ... </parameter> <!-- shared secret between the portal and Nuxeo server --> <parameter name= "maxAge" > ... </parameter> <!-- in seconds --> <parameter name= "digestAlgorithm" > SHA-512 <parameter> </parameters> </authenticationPlugin> </extension> The algorithm used must be one of those described in https://docs.oracle.com/javase/8/docs/technotes/guides/security/StandardNames.html#MessageDigest For compatibility with previous Nuxeo versions, the default is MD5 .
