FIDO U2F Application for Ledger Blue and Nano S
This application implements a U2F Authenticator for Ledger Blue - missing an integration guide and a few power management cleanups.
To compile, generate src/u2f_crypto_data.h with
static const uint8_t ATTESTATION_KEY[] = {
// 32 bytes secp256k1 attestation private key
};
static const uint8_t ATTESTATION_CERT[] = {
// Attestation certificate
};
