EdDSA Example

The EdDSA Example demonstrates how to perform Edwards-curve Digital Signature Algorithm operations using:

• for sign and verify: EdDSA - Edwards-curve Digital Signature Algorithm,
• for key generation and conversion: ECC - Elliptic Curve Cryptography.

Note

This example can run in software or hardware, depending on the supported features of your SoC. It uses the default backend for the specific platform, but you can test it using different backends. For more details on how to change backends, see Configuring nrf_crypto frontend and backends.

You can find the source code and the project file of the example in the following folder: <InstallFolder>\examples\crypto\nrf_crypto\eddsa

Testing

Test the EdDSA Example application by performing the following steps:

1. Skip this step if you are using an RTT viewer.
   Start a terminal emulator like PuTTY and connect to the used COM port with the following UART settings:
   • Baud rate: 115.200
   • 8 data bits
   • 1 stop bit
   • No parity
   • HW flow control: None
2. Compile and program the application.
3. Observe the result of the EdDSA operations in the log using an RTT viewer or a terminal emulator.
