Handle ecdsa-sk flags, reject no-touch For the time being Dropbear will only allow SK auth with default parameters, user-presence needs to be set. In future handling of authorized_keys option "no-touch-required" can be added. This code would also be refactored to share between ecdsa and ed25519 once I get hardware/emulation to test ed25519.

#ifndef DROPBEAR_SK_ED25519_H_
#define DROPBEAR_SK_ED25519_H_

#include "includes.h"

#if DROPBEAR_SK_ED25519

#include "buffer.h"
#include "ed25519.h"

int buf_sk_ed25519_verify(buffer *buf, const dropbear_ed25519_key *key, const buffer *data_buf, const char* app, unsigned int applen);

#endif

#endif /* DROPBEAR_SK_ED25519_H_ */
