IPP Cryptography Library - where are the files as ippcp.h ?

IPP Cryptography Library

The IPP cryptography library files are not included in the above lists, since they are not part of the standard product. If you are using the IPP cryptography library you will need to add those library files to your link list. The crypto files are named ippcp*.

So where are these files ?

i need to to use bignumber but it is impossible because i do not have IPP Cryptography Library ? i precise I bought the product !

thanks for your help
