Key Type Type
Form 1 2
OPIM DATA DATA Use the OP form in encipher. Use key export with the
OP form to communicate ciphertext and key with
another cryptographic partner. Use key import at a
later time to use encipher or decipher with the same
key again.
OPIM MAC MAC Single-length MAC generation key. Use the OP form in
MAC generation. You have no corresponding MACVER key,
but you can call the MAC verification service with
the MAC key directly. Use the key import callable
service and then compute the MAC again using the MAC
verification callable service, which compares the MAC
it generates with the MAC supplied with the message
and issues a return code indicating whether they
compare.
