Detailed Description

public API, basic data types

This file holds the public API of the most basic data types and operations of the pqc NTRU implementation and is meant to be installed on the client system.

Function Documentation

void poly_delete

(

fmpz_poly_t

poly

)

This deletes the internal structure of a polynomial, and frees the pointer.

Parameters:

poly	the polynomial to delete

Definition at line 123 of file ntru_poly.c.

void poly_delete_all	(	fmpz_poly_t	poly,
			...
	)

This deletes the internal structure of all polynomials, and frees the pointers. You must call this with NULL as last argument!

Parameters:

poly	the polynomial to delete
...	follow up polynomials

Definition at line 149 of file ntru_poly.c.

void poly_delete_array

(

fmpz_poly_t **

poly_array

)

Delete the internal structure of a polynomial array which must be NULL terminated. It is expected that poly_array is not on the stack and was obtained by a function like ascii_to_poly().

Parameters:

poly_array

the polynomial array

Definition at line 131 of file ntru_poly.c.

void poly_draw

(

const fmpz_poly_t

poly

)

Draws a polynomial to stdout.

Parameters:

poly

draw this

Definition at line 574 of file ntru_poly.c.

void poly_draw_pretty

(

const fmpz_poly_t

poly

)

Draws a polynomial to stdout, in pretty format.

Parameters:

poly

draw this

Definition at line 583 of file ntru_poly.c.

void poly_new	(	fmpz_poly_t	new_poly,
		int const *const	c,
		const size_t	len
	)

Initializes and builds a polynomial with the coefficient values of c[] of size len within NTRU parameters and returns a newly allocated polynomial. For an empty polynom, both c and len can be NULL/0.

Parameters:

new_poly	the polynomial to initialize and fill with coefficients [out]
c	array of polynomial coefficients, can be NULL
len	size of the coefficient array, can be 0

Returns:

newly allocated polynomial pointer, must be freed with fmpz_poly_clear()

Definition at line 110 of file ntru_poly.c.

void prints

(

const string *

print_string

)

Prints the given string to stdout.

Parameters:

print_string

the print to string

Definition at line 37 of file ntru_string.c.

string* read_file

(

char const *const

filename

)

Reads a file and returns a newly allocated string.

Parameters:

filename

file to open

Returns:

a newly allocated string which must be freed by the caller or NULL on failure

Reads a file and returns a newly allocated string.

Parameters:

filename

file to open

Returns:

a newly allocated string which must be freed by the caller or NULL on failure (e.g. if the file could not be opened/closed)

Definition at line 50 of file ntru_file.c.

void string_delete

(

string *

del_string

)

Delete the inner structure of the string and frees the string itself from the heap. Must not be called on stack variables.

Parameters:

del_string

the string to delete

Definition at line 47 of file ntru_string.c.

void write_file	(	string const *	wstring,
		char const *const	filename
	)

Write a string to a file. The file will be pruned or created if it does not exist.

Parameters:

wstring	the string to write to the file
filename	the name of the file to write to

Write a string to a file. The file will be pruned or created if it does not exist.

Parameters:

wstring	the string to write to the file
filename	the name of the file to write to

Returns:

true for success or false for failure if fopen or fclose failed

Definition at line 107 of file ntru_file.c.
