There doesn't seem to be.  You could call krb5_c_make_random_key and see how
large the resulting key is.

There is a mechanism within the library itself, but in general
external keys should probably come from krb5_c_make_random_key or
krb5_c_string_to_key.

Ideally such an API would be provided along with an implementation of
the RFC 3961 random_to_key functionality.
