* Remove dangling references to BN_get0_nist_prime_521(3)tb2023-04-271-6/+4

* In the next major bump, some BN macros will become functions.schwarze2021-12-061-7/+2
| | | | | | In order to not forget it, already remove the statements that these APIs are currently implemented as macros: Not saying that doesn't make the documentation wrong.

* In view of the recent BN_FLG_CONSTTIME vulnerabilities in OpenSSL,schwarze2018-04-291-21/+38
| | | | | | | | | | | | | | | | carefully document constant time vs. non-constant time operation of BN_div(3), BN_mod_exp(3), and BN_mod_inverse(3). Until the work that is required on the ill-designed BN_exp(3) and BN_gcd(3) interfaces can be undertaken, also document the imperfections in their behaviour, for now. Finally, mention BN_mod_exp(3) behaviour for even moduli. Delete the vague statement about some functions automatically setting BN_FLG_CONSTTIME. It created a false sense of security. Do not rely on it: not all relevant functions do that. Topic brought up by beck@, significant feedback and OK jsing@.

jsing@ confirmed that these macros are public and worth documenting.
