libzpc - A Protected-Key Cryptographic Library
https://www.ibm.com/docs/en/linux-on-systems?topic=library-libzpc-15

There is one enhancement in the libzpc 1.5 version:
libzpc 1.5 now reacts to a verification pattern mismatch caused by live guest relocation or migration by re-creating the protected keys from the key material it was derived from.

There are three new guides around Crypto and Linux on IBM Z.
You can find the publication here:

An update to the publication:
"Pervasive Encryption for Data Volumes"
is now available on
https://www.ibm.com/docs/en/linuxonibm/lxdc/lxdc_linuxonz.html

The main enhancements are the support for retrievable secrets on IBM Secure Execution for Linux guests, the ease of use of passphrases, and the improved handling of #EP11 extractable and #CCA exportable keys.

The Dev team neighboring my Org is looking for an OpenShift Hypervisor Developer. If you want to become a key member of a dynamic team, you will play a vital role in designing, developing and integrating new Core Virtualization features directly into Layered Products such as OpenShift Virtualization (KubeVirt and Kubernetes).

libzpc - A Protected-Key Cryptographic Library 1.3 + 1.4:

libzpc version 1.3 introduces a new protected key origin called ultravisor retrievable secret. You can use protected keys derived from retrievable secrets for encryption and decryption (AES), and for sign and verify operations (ECC) on an IBM z17.
libzpc version 1.4 supports new types of protected keys from origin retrievable secrets:
full-XTS and HMAC protected keys. New groups of function APIs are provided to run on an IBM z17
to perform operations with these new key types.

I love to work with young, motivated talents.
Two of my engineers were asked to elaborate RH HA on #LinuxonZ. The outcome is awesome.

They created a compelling paper with hints and tricks and practical examples to help you configure and use the Red Hat Enterprise Linux High Availability Add-on. Clusters on #lpar #kvm #zVM are covered as well as the use-case to make infrastructure for Red Hat #OpenShift Container Platform highly available.
