Subject: zkey: Add 'convert' command to convert keys from one type to another
From: Ingo Franzki <ifranzki@linux.ibm.com>

Summary:     zkey: Add support for CCA AES CIPHER keys
Description: With CCA 5 there is a new secure key type, the so called 
             variable length symmetric cipher key token. This token format
             can hold AES keys with size 128, 192 and 256 bits together
             with additional attributes cryptographic bound to the key
             token. The attributes may limit the usage of the key, for
             example restrict export or usability scope. So this key type
             is considered to be even more secure than the traditional 
             secure key token. This key token type is also called "CCA
             AES CIPHER key", where the formerly used key token is called
             "CCA AES DATA key".
             The zkey as well as the zkey-cryptsetup tools are enhanced
             to support AES CIPHER keys. That is, zkey can manage AES DATA 
             keys, as well as AES CIPHER keys. The key type must be specified
             at key generation time, the default is to generate AED DATA
             keys.

Upstream-Description:

zkey: Add 'convert' command to convert keys from one type to another

Add a new 'convert' command. It allows to convert a secure key from
             one key type to another. Currently only keys of type CCA-AESDATA can be
             converted to CCA-AESCIPHER.
