Hi all,

 

While going thru various engines, I see that:

- for RSA, the structure is always initialized for rsa_mode_exp and
mod_exp_mont (6th and 7th entities in the RSA_NETHOD structure).  

     - for DH, only mod_ep_dh (4th entity in the DH_METHOD structure)

     - for DSA, dsa_mod_exp and mod_exp_dsa(4th and 5th entities in the
DSA_METHOD structure).

 

Question:  Why there are the other entities (encryption and decryption
in particular) methods are not being initialized?

 

Thanks.

 

Best Regards,

-Sitanshu
