David Laight 44b9597fea keys: Replace strcpy(derived_buf, "AUTH_KEY") with strscpy(..., HASH_SIZE) ...

derived_buf is guaranteed to be HASH_SIZE - and it is more than enough.
The strscpy() degenerates into an memcpy() (as did the strcpy()).
Do the same for the associated "ENC_KEY" copy.

Removes a possibly unbounded strcpy().
