Class Overview

Wrap keys according to draft-ietf-smime-key-wrap-01.txt.

Note:

  • this is based on a draft, and as such is subject to change - don't use this class for anything requiring long term storage.
  • if you are using this to wrap triple-des keys you need to set the parity bits on the key and, if it's a two-key triple-des key, pad it yourself.
