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

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.https://www.ibm.com/docs/en/linux-on-systems?topic=linuxonibm/lxpc/lxpc_linuxonz.htm
