Since we never allow unauthenticated cipher suites in production configurations, it's actually not a problem with the @SECLEVEL solution for those test systems where we do use ADH. Glad that I don't have to use a modified callback. Thanks a lot, Per -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
