mbedtls_ecdsa_from_keypair() function

This function sets up an ECDSA context from an EC key pair. \see ecp.h

Syntax

int mbedtls_ecdsa_from_keypair( mbedtls_ecdsa_context *ctx,     const mbedtls_ecp_keypair *key );
Implemented in ecdsa.c:819

Arguments

ctx

The ECDSA context to setup. This must be initialized.

key

The EC key to use. This must be initialized and hold a private-public key pair or a public key. In the former case, the ECDSA context may be used for signature creation and verification after this call. In the latter case, it may be used for signature verification.

Return value

\c 0 on success. An \c MBEDTLS_ERR_ECP_XXX code on failure.
