Thanks.
> and a CMAC key using the function EVP_PKEY_new_CMAC_key():
That's the step I was missing. Right in front of my eyes.
I'm still missing something though.
Does this look reasonable:
cipher = EVP_aes_128_cbc();
pkey = EVP_PKEY_new_CMAC_key(NULL, key, keylength, cipher);
ctx = EVP_PKEY_CTX_new(pkey, NULL);
EVP_PKEY_sign_init(ctx);
The last step dies with:
error:0608D096:digital envelope routines:EVP_PKEY_sign_init:operation not
supported for this keytype.
[It will probably be obvious after somebody points me in the right direction.]
That cipher work with CMAC.
