FIPS mode, Elytron HTTP DIGEST authentication mechanism not fips compliant -------------------------------------------------------------------------- Key: ELY-1369 URL: https://issues.jboss.org/browse/ELY-1369 Project: WildFly Elytron Issue Type: Bug Components: HTTP Affects Versions: 1.2.0.Beta3 Reporter: Jan Kalina Assignee: Jan Kalina Fix For: 1.2.0.Beta11 Elytron HTTP DIGEST authentication comply to rfc2617 - which means MD5 is used by default (it means it is hardcode, with no way to configure another hash algorithm). But MD5 could make troubles in fips environment [5]. {code:java|title=DigestAuthenticationMechanism.java} String algorithm = convertToken(ALGORITHM, responseTokens.get(ALGORITHM)); if (MD5.equals(algorithm) == false) { throw log.mechUnsupportedAlgorithm(getMechanismName(), algorithm); } {code} There exists proposed rfc7616 which makes algorithm configurable, work on new DIGEST features are covered by [1]. [~dlofthouse] is it planned for [1] to target 7.1?
