Hopefully not many people are writing their own wrappers on ktab that always include the `-f` option. I do want to be consistent with the naming in the MIT krb5 ktutil command.

For consistency, it looks like a new constructor should be added that takes the salt string as a parameter as well. However, I don't intend to add it as I cannot see a proper usage for it. In fact, I now regret adding the constructor linked above.
I will take a look. Thanks~
