mbedtls_ecp_muladd_restartable() function

The ECP group to use. This must be initialized and have group parameters set, for example through mbedtls_ecp_group_load().

The point in which to store the result of the calculation. This must be initialized.

The integer by which to multiply \p P. This must be initialized.

The point to multiply by \p m. This must be initialized.

The integer by which to multiply \p Q. This must be initialized.

The point to be multiplied by \p n. This must be initialized.

The restart context (NULL disables restart).

This function sets up an ECP group context from a standardized set of domain parameters.

This function frees the components of an ECP group.

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 initializes an ECP group context without loading any domain parameters.

This function exports a point into unsigned binary data.

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 \c 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 imports a point from unsigned binary data.

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.

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

This function copies the contents of group \p src into group \p dst.

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 imports a point from a TLS ECPoint record.

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 generates a private key.

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

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 computes the ECDSA signature of a previously-hashed message. \see ecp.h

This function computes the ECDSA signature of a previously-hashed message, deterministic version. For more information, see RFC-6979: Deterministic Usage of the Digital Signature Algorithm (DSA) and Elliptic Curve Digital Signature Algorithm (ECDSA). \see ecp.h

This function exports an elliptic curve as a TLS ECParameters record as defined in RFC 4492, Section 5.4.

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

This function checks if domain parameter A of the curve is \c -3.

This function sets up an ECP group context from a TLS ECParameters record as defined in RFC 4492, Section 5.4.

This function exports generic key-pair parameters. Each of the output parameters can be a null pointer if you do not need that parameter.
