It used to take just a ctx. Now it also wants a key+length and a params. I have some simple/hack code to time 2 cases. The first gives it the key each time. The second preloads the key. That would require an evp per key, but I might we willing to make that space/time tradeoff. The each time mode of my old code put the cipher and key into a params array, then called EVP_MAC_CTX_set_params(ctx, params) and then EVP_MAC_init(ctx) That's easy to change. I just drop putting the key into a params slot and drop calling set_parms and add the key and parms to EVP_MAC_init. That worked. Is there a way to use a preloaded key? I tried using NULL for key and params when calling EVP_MAC_init. It compiles and runs but doesn't get the right answer. Is that, or something like it supposed to work? -------- EVP_MAC_CTX_set_params() seems ugly to me. My inner loop looks like: EVP_MAC_CTX_set_params() EVP_MAC_init() EVP_MAC_update() EVP_MAC_final() I'm trying to make things go fast. It's going to have to do string compares to figure out what I want to do. I'm working with small blocks of data (48 bytes) so the setup cost is important. Or I think it is, so I'm trying to measure it. The case I'm trying to get working is to move the EVP_MAC_CTX_set_params() out of the loop. -- These are my opinions. I hate spam.
