functions in ui_compat. This gave reason to rework that part more
thoroughly, so here are the changes made:
1. Add DES_read_password() and DES_read_2passwords() with the same
functionality as the corresponding old des_ functions, as a
convenience to the users.
2. Add UI_UTIL_read_pw_string() and UI_UTIL_read_pw() with the
functionality from des_read_pw_string() and des_read_pw(), again as
a concenience to the users.
3. Rename des_read_password(), des_read_2passwords(),
des_read_pw_string() and des_read_pw() by changing des_ to
_ossl_old_des_, and add the usual mapping macros.
4. Move the implementation of des_read_password() and
des_read_2passwords() to the des directory, since they are tightly
tied to DES anyway.
This change was inspired by a patch from Assar Westerlund <assar@sics.se>:
There are some functions that didn't get the kick-away-old-des-and-
replace-des-with-DES action. Here's a patch that adds DES_ and des_
(in des_old.h) versions of des_read_pw_string et al. This patch
includes some of the first des_old.h semi-colon macro fixes that I've
already sent.
Implement UI controls. Current controls are the possibility to output
the OpenSSL error stack on the same channel from within UI_process()
and to check if the same user interface can be redone without being
rebuilt (this is often more a question of philosophy than
technicalities).
prompting, application-defined prompts, the possibility to use
defaults (for example default passwords from somewhere else) and
interrupts/cancelations.
(for new functions...). One might still want to be able to pass down
a user-data pointer to be used by the UI. However, ex_data doesn't
quite cut it, since that means the appropriate index to it might need
to be shared between parts that aren't really related in that sense,
and would require the currently hidden (static) index holders to be
uncovered. Not a good thing. Therefore, add the possibility to add a
user-data pointer to a UI.
like des_read_password and friends (backward compatibility functions
using this new API are provided). The purpose is to remove prompting
functions from the DES code section as well as provide for prompting
through dialog boxes in a window system and the like.
