* Cleanup c2i_ASN1_BIT_STRING() code.jsing2018-05-121-20/+23
| | | | | | | | | | Avoid overloading a variable to store both a value and an error code - we can simply inline the error calls (as done everywhere else). Remove a bunch of unnecessary parentheses and tidy a few other things. With input from tb@. ok inoguchi@ tb@

* In view of the recent BN_FLG_CONSTTIME vulnerabilities in OpenSSL,schwarze2018-04-294-28/+104
| | | | | | | | | | | | | | | | 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@.
