NB: This and other manual pages should be updated for the new
BN_GENCB interface.
Both BN_is_prime() and BN_is_prime_fasttest() perform a Miller-Rabin
probabilistic primality test with B<checks> iterations. If
-B<checks == BN_prime_check>, a number of iterations is used that
+B<checks == BN_prime_checks>, a number of iterations is used that
yields a false positive rate of at most 2^-80 for random input.
If B<callback> is not B<NULL>, B<callback(1, j, cb_arg)> is called
