Support Modular Crypt Format (MCF) password in Bcrypt mapper ------------------------------------------------------------ Key: ELY-1497 URL: https://issues.jboss.org/browse/ELY-1497 Project: WildFly Elytron Issue Type: Enhancement Components: Passwords Affects Versions: 1.1.7.Final Reporter: Tom Stiemerling Assignee: Darran Lofthouse Priority: Major Fix For: 1.9.0.Final Currently BCrypt mapper for DB realm does not support MCF format passwords (which does not require explicit salt or iterations): {noformat} 17:42:28,328 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 3) WFLYCTL0013: Operation ("add") failed - address: ([ ("subsystem" => "elytron"), ("jdbc-realm" => "DatabaseRealm") ]) - failure description: "WFLYCTL0155: 'salt-index' may not be null" {noformat} Support should be added to support MCF password so only single column needed in DB. Logic: {code} if (password && !salt && !iterations) assume MCF format password else if (password && salt && iterations) assume BCrypt (b64) password, etc else error {code}
