patches that Geoff had in a patch file in his play directory.
NOTE for openssl-cvs: THIS IS A CVS BRANCH (BRANCH_engine). IT IS
NOT FOR THE FAINTHEARTED TO PLAY WITH. The code works as it is, but
it's not at all sure it ends up in the OpenSSL distributio in this
form, so do not get dependent on it!
Those rsyncing the repository are considered warned!
Never use des_set_key (it depends on the global variable des_check_key),
but usually des_set_key_unchecked.
Only destest.c bothered to look at the return values of des_set_key,
but it did not set des_check_key -- if it had done so,
most checks would have failed because of wrong parity and
because of weak keys.
(meaning pointer to char) to des_cblock * (meaning pointer to
array with 8 char elements), which allows the compiler to
do more typechecking. (The changed argument types were of type
des_cblock * back in SSLeay, and a lot of ugly casts were
used then to turn them into pointers to elements; but it can be
done without those casts.)
Introduce new type const_des_cblock -- before, the pointers rather
than the elements pointed to were declared const, and for
some reason gcc did not complain about this (but some other
compilers did).
