- Add --keepold/keepallold/pruneall options to various kadmin/ktutil
commands. Default behavior to "prune old keys".
- When setting keys for a service, we need to specify enctypes for it:
- Always use kadm5_randkey_principal_3() instead of the older
kadm5_randkey_principal().
- Add krb5_string_to_keysalts2(), like MIT's krb5_string_to_keysalts(),
but with a context, and simpler.
- Add --enctypes options to various kadmin/ktutil commands.
- Add [libdefaults] supported_enctypes param with enctype[:salttype]
list.
- Add [realms] realm supported_enctypes param with enctype[:salttype]
list.
Default to aes128-cts-hmac-sha1-96:normal.
lib/krb5/crypto.c was a large, monolithic block of code which made
it very difficult to selectively enable and disable particular
alogrithms.
Reorganise crypto.c into individual files for each encryption and
salt time, and place the structures which tie everything together
into their own file (crypto-algs.c)
Add a non-installed library (librfc3961) and test program
(test_rfc3961) which builds a minimal rfc3961 crypto library, and
checks that it is usable.
