>   today.  The Cryptographic Message Syntax (CMS) supports key transport
>   and key agreement algorithms that could be broken by the invention of

>   protected with the CMS today, someone could decrypt them in the
>   future when a large-scale quantum computer becomes available.  Once
>   quantum-secure key management algorithms are available, the CMS will
>   be extended to support the new algorithms, if the existing syntax
>   does not accommodate them.  In the near-term, this document describes
>   a mechanism to protect today's communication from the future
>   invention of a large-scale quantum computer by mixing the output of
>   key transport and key agreement algorithms with a pre-shared key.
