CKM_ECDH1_DERIVE
Elliptic Curve Diffie-Hellman is an anonymous key-agreement protocol. CKM_ECDH1_DERIVE is the derive function for that protocol.
NOTE To enhance performance, we have created a proprietary call CA_DeriveKeyAndWrap, which is an optimization of C_DeriveKey with C_Wrap, merging the two functions into one (the in and out constraints are the same as for the individual functions). A further optimization is applied when mechanism CKM_ECDH1_DERIVE is used with CA_DeriveKeyAndWrap.
If CA_DeriveKeyAndWrap is called with other mechanisms, those would not be optimized.
NOTE The BIP32 key type is not available in FIPS mode.
