crypto_ec_point_deinit() function

crypto_ec_point_to_bin - Write EC point value as binary data @e: EC context from crypto_ec_init() @p: EC point data from crypto_ec_point_init() @x: Buffer for writing the binary data for x coordinate or %NULL if not used @y: Buffer for writing the binary data for y coordinate or %NULL if not used Returns: 0 on success, -1 on failure This function can be used to write an EC point as binary data in a format that has the x and y coordinates in big endian byte order fields padded to the length of the prime defining the group.

crypto_bignum_mul - res = b * p @e: EC context from crypto_ec_init() @p: EC point @b: Bignum @res: EC point; used to store the result of b * p Returns: 0 on success, -1 on failure

crypto_bignum_add - c = a + b @e: EC context from crypto_ec_init() @a: Bignum @b: Bignum @c: Bignum; used to store the result of a + b Returns: 0 on success, -1 on failure

crypto_ec_point_is_at_infinity - Check whether EC point is neutral element @e: EC context from crypto_ec_init() @p: EC point Returns: 1 if the specified EC point is the neutral element of the group or 0 if not

crypto_ec_point_is_on_curve - Check whether EC point is on curve @e: EC context from crypto_ec_init() @p: EC point Returns: 1 if the specified EC point is on the curve or 0 if not

crypto_ec_get_affine_coordinates : get affine coordinate of ec curve @e: ec curve @pt: point @x: x coordinate @y: y coordinate Return : 0 if success

crypto_ec_point_invert - Compute inverse of an EC point @e: EC context from crypto_ec_init() @p: EC point to invert (and result of the operation) Returns: 0 on success, -1 on failure

crypto_ec_point_solve_y_coord - Solve y coordinate for an x coordinate @e: EC context from crypto_ec_init() @p: EC point to use for the returning the result @x: x coordinate @y_bit: y-bit (0 or 1) for selecting the y value to use Returns: 0 on success, -1 on failure

crypto_ec_point_cmp - Compare two EC points @e: EC context from crypto_ec_init() @a: EC point @b: EC point Returns: 0 on equal, non-zero otherwise
