Cryptographic Development Kits (CDKs)
Available from Information Security Magazine
ISC CDKs are flexible, cost effective libraries of linkable cryptographic modules that allow you to add encryption, digital signatures, and message authentication to any application. They reduce the cost of developing secure applications by applying readily available, commercially supported, conventional and public key technology.
ISC CDKs make standards-based cryptographic building blocks available to developers and integrators. Use them to construct secure corporate applications for internal use or OEM products for resale.
