IBM Global Security Kit (GSKit) is a library and set of command-line tools that provides SSL implementation along with base cryptographic functions (symmetric and asymmetric ciphers, random number generation, hashing, and so on) and key management.
The underlying cryptographic library, IBM Crypto for C (ICC), is FIPS certified.
GSKit is used by many IBM software products for its security, usability, and FIPS certification. Some products expose and even require a user to use GSKit utilities for certain tasks, while others wrap GSKit's capabilities in their own interfaces.
GSKit is a component and not a stand-alone product. It is not obtainable independent of the products that ship it. GSKit support and updates are provided as part of other products' support and updates.
