Hardware and software prerequisites
Support for Crypto Express features depends on the IBM Z® or IBM® LinuxONE hardware model.
Table 1 lists the support for the cryptographic
adapters.
| Cryptographic adapters | Hardware support |
|---|---|
| CEX8A, CEX8C, and CEX8P | IBM z16™ |
| CEX7A, CEX7C, and CEX7P | IBM z16, z15® and IBM LinuxONE III |
| CEX6A, CEX6C, and CEX6P | IBM z16, z15, z14, z14 ZR1, IBM LinuxONE III, and IBM LinuxONE II |
| CEX5A, CEX5C, and CEX5P | z15, z14, z13®, z13s®, IBM LinuxONE III, IBM LinuxONE II, and IBM LinuxONE |
| CEX4A, CEX4C, and CEX4P | zEC12 and zBC12 |
Crypto Express8S adapters can handle larger request and reply sizes than earlier cryptographic adapters. The software that manages Crypto Express8S adapters must support these larger request and reply sizes.
Table 2 lists the required software by
function.
| Software required | Function that is supported by the software |
|---|---|
| The CCA library | For the secure key cryptographic functions on CCA coprocessors. For information about cryptographic CCA coprocessors, coexistence of adapter versions, and how to use CCA functions, see Secure Key Solution with the Common Cryptographic Architecture Application Programmer's Guide, SC33-8294. You can obtain this publication at https://www.ibm.com/docs/linuxonibm/liaaf/lnz_r_ccacnt.html. |
| The EP11 library | For the secure key cryptographic functions on EP11 coprocessors. See Exploiting Enterprise PKCS #11 using openCryptoki, SC34-2713. You can obtain this publication at ibm.com/docs/en/linux-on-systems?topic=overview-exploiting-enterprise-pkcs-11-using-opencryptoki. |
| The libica library | For the clear key cryptographic functions. See libica Programmer's Reference, SC34-2602. You can obtain this publication at ibm.com/docs/en/linux-on-systems?topic=overview-libica-programmers-reference. |
