+  ECCX08 Signing
+
+  This sketch uses the ECC508 or ECC608 to sign some data
+  using the private key of a key slot, the signature
+  is printed to the Serial monitor. Then the signature is
+  verified using the public key of the slot.
+
+  NOTE: the input data must be 64 bytes in length!
+
+  Circuit:
+   - MKR board with ECC508 or ECC608 on board
