This example uses the SE Manager API to perform asymmetric key handling on the supported Series 2 device.
In this example, SE Manager is used to first generate a public/private asymmetric key pair (plaintext, wrapped, and volatile) using a given Elliptic Curve Cryptography (ECC) curve. The public key is then exported from the key pair and it can be used to verify the public key after exporting or transferring a key in the Secure Vault device.
The example redirects standard I/O to the virtual serial port (VCOM) of the kit. By default, the serial port setting is 115200 bps and 8-N-1 configuration.
The example has been instrumented with code to count the number of clock cycles spent in different operations. The results are printed on the VCOM serial port console. This feature can be disabled by defining SE_MANAGER_PRINT=0 (default is 1) in the IDE setting (Preprocessor->Defined symbols).
The following key types are supported in this example:
