mbedtls_ecp_point_read_string() function

The destination point. This must be initialized.

The numeric base of the input.

The first affine coordinate, as a null-terminated string.

The second affine coordinate, as a null-terminated string.

This function frees the components of a point.

This function initializes a point as zero.

This function copies the contents of point \p Q into point \p P.

This function performs multiplication of a point by an integer: \p R = \p m * \p P in a restartable way. \see mbedtls_ecp_mul()

This function performs a scalar multiplication of a point by an integer: \p R = \p m * \p P. It is not thread-safe to use same group in multiple threads.

This function sets a point to the point at infinity.

This function checks if a point is the point at infinity.

This function imports a point from unsigned binary data.

This function imports a point from a TLS ECPoint record.

This function exports a point as a TLS ECPoint record defined in RFC 4492, Section 5.4.

This function generates an ECDH keypair on an elliptic curve. This function performs the first of two core computations implemented during the ECDH key exchange. The second core computation is performed by mbedtls_ecdh_compute_shared(). \see ecp.h

This function performs multiplication and addition of two points by integers: \p R = \p m * \p P + \p n * \p Q in a restartable way. \see \c mbedtls_ecp_muladd()

This function checks that a point is a valid public key on this curve. It only checks that the point is non-zero, has valid coordinates and lies on the curve. It does not verify that it is indeed a multiple of \p G. This additional check is computationally more expensive, is not required by standards, and should not be necessary if the group used has a small cofactor. In particular, it is useless for the NIST groups which all have a cofactor of 1.

This function generates an ECP keypair.

This function exports a point into unsigned binary data.

This function computes the shared secret. This function performs the second of two core computations implemented during the ECDH key exchange. The first core computation is performed by mbedtls_ecdh_gen_public(). \see ecp.h

This function generates a keypair with a configurable base point.

This function verifies the ECDSA signature of a previously-hashed message. \see ecp.h

This function compares two points.

This function performs multiplication and addition of two points by integers: \p R = \p m * \p P + \p n * \p Q It is not thread-safe to use same group in multiple threads.

Print an ECP point to the debug output. This function is always used through the MBEDTLS_SSL_DEBUG_ECP() macro, which supplies the ssl context, file and line number parameters. \attention This function is intended for INTERNAL usage within the library only.
