mbedtls_ecjpake_derive_secret() function

The ECJPAKE context to use. This must be initialized, set up and have performed both round one and two.

The buffer to write the derived secret to. This must be a writable buffer of length \p len Bytes.

The length of \p buf in Bytes.

The address at which to store the total number of Bytes written to \p buf. This must not be \c NULL.

The RNG function to use. This must not be \c NULL.

The RNG parameter to be passed to \p f_rng. This may be \c NULL if \p f_rng doesn't use a context.

Read and process the first round message (TLS: contents of the Client/ServerHello extension, excluding extension type and length bytes).

Read and process the second round message (TLS: contents of the Client/ServerKeyExchange).

Generate and write the first round message (TLS: contents of the Client/ServerHello extension, excluding extension type and length bytes).

Generate and write the second round message (TLS: contents of the Client/ServerKeyExchange).

This clears an ECJPAKE context and frees any embedded data structure.

Initialize an ECJPAKE context.

Set up an ECJPAKE context for use.

Check if an ECJPAKE context is ready for use.

Write the shared key material to be passed to a Key Derivation Function as described in RFC8236.

Set the point format for future reads and writes.
