[keycloak-user] Crypto

Hy guys, I am trying to use some crypto to match hashes from my old db. The code is : KeySpec keySpec = new PBEKeySpec(password.toCharArray(), salt.getBytes(), 2048, 160); SecretKeyFactory secretKeyFactory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1"); byte[] hash = secretKeyFactory.generateSecret(keySpec).getEncoded(); I cant make it work as a federation provider. it was complaining about java.lang.ClassNotFoundException: javax.crypto.spec.PBEKeySpec I added jce.jar to the list of dependencies in my module.xml (I shouldn’t have to do that) Then I got : ClassNotFoundException: sun.security.jca.GetInstance I added rt.jar (which I shouldn’t do either) and then I got some fancy exception : java.lang.LinkageError: loader constraint violation I then tried with bouncy castle : bcprov-jdk15on-152.jar to no avail. what is wrong ? here is my module.xml file : <?xml version="1.0" encoding="UTF-8"?> <module xmlns="urn:jboss:module:1.1" name="com.imetrik.saas.server.services.insuranceWebUIBackend.dao.federation"> <resources> <resource-root path="insuranceWebUIBackend-lib-2.0.5-SNAPSHOT.jar"/> <resource-root path="jdbi-2.63.1.jar"/> <resource-root path="postgresql-9.4-1203-jdbc4.jar"/> <resource-root path="slf4j-api-1.7.12.jar"/> <resource-root path="slf4j-simple-1.7.12.jar"/> <resource-root path="global-library-common-2.0.4.jar"/> <resource-root path="jce.jar"/> <resource-root path="bcprov-jdk15on-152.jar"/> </resources> <dependencies> <module name="org.keycloak.keycloak-core"/> <module name="org.keycloak.keycloak-model-api"/> </dependencies> </module> Cheers. ________________________________ REMI CARTIER B.O.S.S.
