It would be useful to record an event each time a JCE cryptographic service for a specific algorithm is requested and/or used. This would help users determine what crypto algorithms their applications are using, and help flag/detect usages of weak algorithms. The JDK does not currently disable weak algorithms at the JCE layer, so these events would help users spot direct or other usages of these algorithms from which they could then determine if it is a security risk or not. It could also potentially record algorithms supplied by 3rd-party JCE providers.
