Default ASYM_ENCRYPT asym_keylength is considered breakable ----------------------------------------------------------- Key: WFLY-11169 URL: https://issues.jboss.org/browse/WFLY-11169 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 14.0.0.Final Reporter: Radoslav Husar Assignee: Radoslav Husar Priority: Major Fix For: 15.0.0.Alpha1 JGroups default asym_keylength is 512, however RSA keys less than 1024 bits are considered breakable (e.g. https://www.oracle.com/technetwork/java/javase/8-compatibility-guide-2156... ) We should baseline the default to a secure size universally supported in our supported JDKs. Also, since JDK8 the default is 2048.
