Thanks for clarifying that for my.
Using the example code at http://www.fredriks.se/?p=23, I've duplicated
everything of the GCM mode for the CCM mode with the addition of setting the
tag length in the beginning of the encryption function.
The encryption succeed BUT the decryption fails.
Just want to add that I do set the data sizes before EncryptUpdate and
DecryptUpdate and mentioned in the CCM section of the OpenSSL support page.
This page does answer both my questions (appologies), but I still fail to
decrypt.

CMAC needs a separate API because it doesn't behave like a normal cipher.
Check out the CMAC_* functions. They behave in a very similar way to the
HMAC_* functions except they take a cipher instead of a digest

Hey - why not make this a test?

Hi all,
Are RAND_seed(), RAND_add() NIST SP 800-151A compliant ?
NIST SP 800-151A compliant enforces that
RBGs specified in SP 800-90 (HASH, HMAC, CTR, DUAL_EC) and ANS X9.62-2005
(HMAC) are acceptable standards
I think this depends on the engine being loaded. HOwever, not sure what
engine is
Dr. Henson and Matt,
Thanks a lot for all the help - my code is also now working. I simply had to
not do the DecryptFinal().
The fact that one can call the xxxUpdate() only once is a problem for using our
engine. For now a size limit will have to be a limitation on this AES mode.
