Besides, EVP_PKEY_CTX_new_id(3) does not produce an EVP_MD_CTX object. Instead, mention the easiest way to actually get the job done using EVP_PKEY_new_CMAC_key(3) and EVP_DigestSignInit(3).

Once this is gone, we can simplify the CMAC code a bit. ok jsing Clarify that the ENGINE argument is ignored; OK tb@. 2023-12-25T15:52:18+00:00 schwarze 2023-12-25T15:52:18+00:00 urn:sha1:2594e6f384c875ce2c2cd2a94d73f19e77244c78 While here, also switch the argument placeholder from *impl to *engine as suggested by tb@. delete another word to improve the wording; suggested by jmc@ 2020-08-06T22:17:49+00:00 schwarze 2020-08-06T22:17:49+00:00 urn:sha1:ad80f89c979f67100839da48dfd0910c6039ad62 Explain the purpose of CMAC_resume(3) in more detail. 2020-08-06T15:40:29+00:00 schwarze 2020-08-06T15:40:29+00:00 urn:sha1:0d60cc36d75fe570b014800800b275a6b603296d Triggered by jmc@ apparently misunderstanding the intention of the text and fixing a grammatical error in a way that wasn't ideal, so i guess he wouldn't have been the only one to find the previous version hard to understand.
