Use the ECC Diffie-Hellman callable service to create:

• Symmetric key material from a pair of ECC keys using the Elliptic Curve Diffie-Hellman protocol and the static unified model key agreement scheme.
• “Z" – The “secret" material output from D-H process.

Output may be one of the following forms:

• Internal CCA Token (DES or AES): AES keys are in the "Variable-length Symmetric Key Token" format. DES keys are in the "DES Internal Key Token" format.
• External CCA Token (DES or AES): AES keys are in the "Variable-length Symmetric Key Token" format. DES keys are in the "DES External Key Token" format.
• “Z" – The “secret" material output from D-H process.
