Hi all, I'm trying to write an engine for EVP ciphers; everything is fine, but I've problems to set the IV.
Should the IV be set using the EVP_CipherInit_ex function? If yes, why in the application (openssl-snapshot-20080107) such a function is called: - with iv=NULL the first time (apps/enc.c:554) - with cipher=NULL the second time (apps/enc.c:565) which actually avoids the iv to be set (because the if in crypto/evp/evp-enc.c:109 fails). Is it a kind of bug or the IV in an engine must be set other-way? Thanks and regards. -- Davide
