Asymmetric Cryptography Commands

The Asymmetric Cryptography command set is made up of those commands that are specifically used to generate or use ECC keys. Keys are typically stored in Data zone slots, but for some commands could also be in the SRAM array.

Table 1. Asymmetric Cryptography Commands
Command Name	Opcode	Description
`ECDH`	0x43	Generates an ECDH pre-master secret using the stored private key and input public key.
`GenKey`	0x40	Generates an ECC private key or optionally generates an ECC public key from the stored private key.
`Sign`	0x41	Signs an internal or external message digest using an ECC private key with an ECDSA signature calculation.
`Verify`	0x45	Verifies an internal or external message digest using an ECC public key with an ECDSA verify calculation.
