ICSF provides callable services that comply with IBM’s Common Cryptographic Architecture (CCA). This allows application programs written in high-level languages such as C, COBOL, FORTRAN, and PL/I, as well as in Assembler, to be used under more than one cryptographic product.
Another family of products that provide these services is the IBM 4765 PCIe and IBM 4764 PCI-X Cryptographic Coprocessors.
