Function Documentation

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

Export the private key to a file.

Parameters

filename	the file to save the private key into
priv	the private key
params	the NTRU context

Definition at line 111 of file ntru_keypair.c.

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

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

Definition at line 96 of file ntru_keypair.c.

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

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

Parameters

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

Definition at line 157 of file ntru_keypair.c.

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

Import the public key from a file.

Parameters

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

Definition at line 132 of file ntru_keypair.c.

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

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

Parameters

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

Returns

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

Definition at line 47 of file ntru_keypair.c.

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
