MISSISSAUGA, Ontario – (March 29, 2005)– Certicom Corp. (TSX: CIC), the authority for strong, efficient cryptography, today announced that Apani Networks, a leading provider of encryption and access control solutions to secure data flows, has licensed Certicom's proven Security Builder® IPSec™ toolkit to help it expand into the mobile security market. By using the widely-implemented Certicom toolkit to build mobile IPSec-compliant virtual private network (VPN) clients, Apani can significantly reduce development costs and accelerate time-to-market of its product.
