Strong encryption and license

Kudos for this great library!
I just want to ask if using Ionic.dll for unzipping and decrypting zip files protected with a
password , do I need a license from PKWARE too ? that's because of the sections :

7.0 "Strong Encryption Specification" and
__10.1 "The Use or Implementation in a product of APPNOTE technological
components pertaining to either strong encryption or patching requires
a separate, executed license agreement from PKWARE. "__

included in the Appnote.txt
