RHBA-2009:1685 - Bug Fix Advisory

Topic

Updated openCryptoki packages that resolve several issues are now available.

Description

The openCryptoki package contains version 2.11 of the PKCS#11 API,
implemented for IBM Cryptocards. This package includes support for the IBM
4758 Cryptographic CoProcessor (with the PKCS#11 firmware loaded), the IBM
eServer Cryptographic Accelerator (FC 4960 on IBM eServer System p), the
IBM Crypto Express2 (FC 0863 or FC 0870 on IBM System z), the IBM CP Assist
for Cryptographic Function (FC 3863 on IBM System z).

These updated openCryptoki packages provide fixes for the following bugs:

• after initializing a hardware cryptographic token, attempting to unwrap

an AES key failed and caused openCryptoki to return a
"CKR_TEMPLATE_INCOMPLETE" error code. With this update, AES key unwrapping
now succeeds as expected. (BZ#540471)

• the openCryptoki API enables programs to offload the computation of the

message authentication code (MAC) to the Central Processor Assist for
Cryptographic Function (CPACF) of cryptographic hardware. When using
PKCS#11 for the acceleration of cryptographic instructions, openCryptoki
returned an error code of "411", indicating that the MAC was unable to be
verified. With this update, the MAC is now computed successfully after
being offloaded to the CPACF. (BZ#540474)

• openCryptoki was not properly recognizing that secure-key crypto support

was installed, and so the "CCA" token was not being enabled for use. (BZ#545379)

All users of openCryptoki are advised to upgrade to these updated packages,
which resolve these issues.

Solution
