The existing pkcs5_pbdkf2 keygen method is retained functionally
as-is, for compatibility with existing params files. The corrected
algorithm, which is now the default for new params file generation, is
called pkcs5_pbkdf2/sha1.
NB. The backwards compatibility for the miscreant keygen method will
be removed at the same time as support for the previous parameters
file syntax. Sometime between now and then, users should update their
params files using -G, which will create a new params file including
an xor value so that the resulting generated key is the same; they
should also

keygen_iteration to 128. This will not default the iteration count
on a new style parameter file as it is an error in the new style
to fail to specify the iteration count.

64 bit block pointers, extended attribute storage, and a few
other things.
This commit does not yet include the code to manipulate the extended
storage (for e.g. ACLs), this will be done later.

FreeBSD.
o added new features:
o -G: generate a new paramsfile that produces the same
key as the old paramsfile,
o ffs verify_method,
o multiple keygen methods that are xor'ed together
(for n-factor authentication), and
o calibrating the iteration count of PKCS#5 PBKDF2 to
the current machine's speed.
o changed paramsfile format to allow for the new features.
o replaced open-coded parser with yacc grammar.
o lots of supporting changes.
o updated documentation to reflect new features and new
paramsfile format.
to reprompt for the passphrase if the key does not meet certain
criteria. The currently implemented methods are ``none'' and
``disklabel''. The first behaves in the original fashion, the
second will scan for a disklabel on the cgd after configuration
and if it does not find a disklabel then it will reprompt for the
password and reconfigure the disk.
