Detailed Description

public API, key handling

This file holds the public API of generating, exporting and importing public and private keys of the pqc NTRU implementation and is meant to be installed on the client system.

Definition in file ntru_keypair.h.

Typedef Documentation

typedef struct keypair keypair

Definition at line 42 of file ntru_keypair.h.

Function Documentation

void export_public_key	(	char const *const	filename,
		const fmpz_poly_t	pub,
		const ntru_params *	params
	)		const

Export the public key to a file.

Parameters

filename	the file to save the public key into
pub	the public key
params	the NTRU context Export the private key to a file.
filename	the file to save the private key into
priv	the private key
params	the NTRU context

void import_priv_key	(	fmpz_poly_t	priv,
		fmpz_poly_t	priv_inv,
		char const *const	filename,
		const ntru_params *	params
	)

Import the private key from a file and store him along with his inverse.

Parameters

priv	where to save the private key [out]
priv_inv	where to save the inverse of the private key [out]
filename	the file to get the private key from
params	the NTRU context

void const fmpz_poly_t const ntru_params* params void import_public_key	(	fmpz_poly_t	pub,
		char const *const	filename,
		const ntru_params *	params
	)

Import the public key from a file.

Parameters

pub	where to save the public key [out]
filename	the file to get the public key from
params	the NTRU context

bool ntru_create_keypair	(	keypair *	pair,
		const fmpz_poly_t	f,
		const fmpz_poly_t	g,
		const ntru_params *	params
	)

Creates an NTRU key pair, consisting of public and private components.

Parameters

pair	store private and public components here [out]
f	a random polynomial
g	a random polynomial
params	the NTRU context

Returns

true for success, false if f or g are not invertible (then the caller hast to try different ones)

void ntru_delete_keypair

(

keypair *

pair

)

Used to free the inner structure of a keypair. This will not call free() on the pair itself.

Parameters

pair	the pair to free the inner structure of
