mbedtls_ecdh_read_public() function

The ECDH context to use. This must be initialized and bound to a group, for example via mbedtls_ecdh_setup().

The pointer to the ClientKeyExchange payload. This must be a readable buffer of length \p blen Bytes.

The length of the input buffer \p buf in Bytes.

This function sets up the ECDH context with the information given. This function should be called after mbedtls_ecdh_init() but before mbedtls_ecdh_make_params(). There is no need to call this function before mbedtls_ecdh_read_params(). This is the first function used by a TLS server for ECDHE ciphersuites.

This function derives and exports the shared secret. This is the last function used by both TLS client and servers. \see ecp.h

This function frees a context.

This function generates an EC key pair and exports its in the format used in a TLS ServerKeyExchange handshake message. This is the second function used by a TLS server for ECDHE ciphersuites. (It is called after mbedtls_ecdh_setup().) \see ecp.h

This function parses the ECDHE parameters in a TLS ServerKeyExchange handshake message. \see ecp.h

This function generates a public key and exports it as a TLS ClientKeyExchange payload. This is the second function used by a TLS client for ECDH(E) ciphersuites. \see ecp.h

This function initializes an ECDH context.

This function sets up an ECDH context from an EC key. It is used by clients and servers in place of the ServerKeyEchange for static ECDH, and imports ECDH parameters from the EC key information of a certificate. \see ecp.h

Print a field of the ECDH structure in the SSL context to the debug output. This function is always used through the MBEDTLS_SSL_DEBUG_ECDH() macro, which supplies the ssl context, file and line number parameters. \attention This function is intended for INTERNAL usage within the library only.
