mbedtls_ecdsa_read_signature_restartable() function
This function reads and verifies an ECDSA signature, in a restartable way. \see \c mbedtls_ecdsa_read_signature()
Syntax
int mbedtls_ecdsa_read_signature_restartable( mbedtls_ecdsa_context *ctx,
const unsigned char *hash,
size_t hlen,
const unsigned char *sig,
size_t slen,
mbedtls_ecdsa_restart_ctx *rs_ctx );
Implemented in ![]()
ecdsa.c:736
Return value
\c 0 on success. #MBEDTLS_ERR_ECP_BAD_INPUT_DATA if signature is invalid. #MBEDTLS_ERR_ECP_SIG_LEN_MISMATCH if there is a valid signature in \p sig, but its length is less than \p siglen. #MBEDTLS_ERR_ECP_IN_PROGRESS if maximum number of operations was reached: see \c mbedtls_ecp_set_max_ops(). Another \c MBEDTLS_ERR_ECP_XXX or \c MBEDTLS_ERR_MPI_XXX error code on failure for any other reason.
Notes
This function is like \c mbedtls_ecdsa_read_signature() but it can return early and restart according to the limit set with \c mbedtls_ecp_set_max_ops() to reduce blocking.

Description
This function frees the components of a key pair.
This function frees an ECDSA context.
This function initializes an ECDSA context.
This function initializes a key pair as an invalid one.
This function sets up an ECDSA context from an EC key pair. \see ecp.h
This function computes the ECDSA signature and writes it to a buffer, serialized as defined in RFC-4492: Elliptic Curve Cryptography (ECC) Cipher Suites for Transport Layer Security (TLS). \warning It is not thread-safe to use the same context in multiple threads. \see ecp.h
This function computes the ECDSA signature and writes it to a buffer, in a restartable way. \see \c mbedtls_ecdsa_write_signature()
This function reads and verifies an ECDSA signature. \see ecp.h
This function checks that the keypair objects \p pub and \p prv have the same group and the same public point, and that the private key in \p prv is consistent with the public key.
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
