I am not sure "nonsense" if some distro are doing something in this
area. Right or,
perhaps, sometime wrong (o perhaps sometime break).
http://fedoraproject.org/wiki/FedoraCryptoConsolidation
FIPS spec is clearly nonsense, from a technical perspective. E.g. it required
support of Dual_EC_DRBG random number generator which was proven to be
inferior and almost certainly has an NSA backdoor.
The Fedora crypto consolidation rationale is completely bogus; in unifying the
crypto database across the entire machine it fails to recognize that different
services (and different clients) will have completely different security
policies and requirements. Of course this is common knowledge for actual
security practitioners - servers generally should only recognize and trust
client certificates issued by a single CA, while clients generally need to be
able to trust many different CAs for a wide range of services. HTTP servers
have much different certificate requirements from LDAP/FTP/SMTP servers;
almost nobody uses client certificates with HTTP but they are commonplace for
many other authenticated services.
Of course, the Fedora crypto scene is dictated more by political concerns than
technical. https://bugzilla.redhat.com/show_bug.cgi?id=319901
