      Add the content type attribute to additional CMS signerinfo. · d63d841f

      Fixes #8923
      
      Found using the openssl cms -resign option.
      This uses an alternate path to do the signing which was not adding the required signed attribute
      content type. The content type attribute should always exist since it is required is there are
      any signed attributes.
      As the signing time attribute is always added in code, the content type attribute is also required.
      The CMS_si_check_attributes() method adds validity checks for signed and unsigned attributes
      e.g. The message digest attribute is a signed attribute that must exist if any signed attributes
      exist, it cannot be an unsigned attribute and there must only be one instance containing a single
      value.

      Allow specifying the tag after AAD in CCM mode · b48e3be9
      Tobias Nießen authored
      
      
      This change allows to pass the authentication tag after specifying
      the AAD in CCM mode. This is already true for the other two supported
      AEAD modes (GCM and OCB) and it seems appropriate to match the
      behavior.
      
      GCM and OCB also support to set the tag at any point before the call
      to `EVP_*Final`, but this won't work for CCM due to a restriction
      imposed by section 2.6 of RFC3610: The tag must be set before
      actually decrypting data.
      
      This commit also adds a test case for setting the tag after supplying
      plaintext length and AAD.
