I know that this question had been asked millions of times, I searched the maillist archives and I know it, and this is not a homework for an academic project, trust me :)
In [1], Victor said that we don't need to rebuild OpenSSL just for adding a crypto algrorithm, and he recoment to see the ccgost engine, I did, but I think that if we add a symmetric cipher, we will declare a EVP_CIPHER struct, which contains a nid, let's say NID_id_Gost28147_89, this nid was defined in crypto/objects/obj_mac.h, but if I don't have a nid for my new added cipher, I think we should add one into openssl, in that occasion I think we should rebuild the OpenSSL. I am appreciated if somebody could help to explain. [1] http://openssl.6102.n7.nabble.com/add-a-new-cipher-to-OpenSSL-td22968.html Cheers!
