suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this
defect would be very difficult to perform and are not believed likely. Attacks against DH512 are
considered just feasible. However, for an attack the target would have to re-use the DH512 private
key, which is not recommended anyway. Also applications directly using the low level API
BN_mod_exp may be affected if they use BN_FLG_CONSTTIME.");
