From 65e2f56a8a10877964fb9fc57963d1bf8104801a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Parm=C3=A9nides=20GV?= Date: Thu, 20 Jun 2013 17:47:07 +0200 Subject: No binary library needed. I've decided not to include any lib, but to copy the SRPParameters class to our codebase and Util.trim method to ConfigHelper. --- src/org/jboss/security/srp/SRPParameters.java | 150 ++++++++++++++++++++++++++ 1 file changed, 150 insertions(+) create mode 100644 src/org/jboss/security/srp/SRPParameters.java (limited to 'src/org/jboss') diff --git a/src/org/jboss/security/srp/SRPParameters.java b/src/org/jboss/security/srp/SRPParameters.java new file mode 100644 index 00000000..4b188cb3 --- /dev/null +++ b/src/org/jboss/security/srp/SRPParameters.java @@ -0,0 +1,150 @@ +/* + * JBoss, Home of Professional Open Source. + * Copyright 2006, Red Hat Middleware LLC, and individual contributors + * as indicated by the @author tags.
