With this patch the paes ciphers do accept AES clear key values of
size 16, 24 or 32 byte. The key value is internal rearranged to form a
paes clear key token so that the pkey kernel module recognizes and
handles this key material as source for protected keys.
Using clear key material as a source for protected keys is a security
risc as the raw key material is kept in memory. However, so the AES
selftests provided with the testmanager can be run during registration
of the paes ciphers.
