mbedtls_pk_sign_restartable() function
Restartable version of \c mbedtls_pk_sign()
Syntax
int mbedtls_pk_sign_restartable( mbedtls_pk_context *ctx,
mbedtls_md_type_t md_alg,
const unsigned char *hash,
size_t hash_len,
unsigned char *sig,
size_t *sig_len,
int (*f_rng)(void *, unsigned char *, size_t),
void *p_rng,
mbedtls_pk_restart_ctx *rs_ctx );
Implemented in ![]()
pk.c:362
Return value
See \c mbedtls_pk_sign(), or #MBEDTLS_ERR_ECP_IN_PROGRESS if maximum number of operations was reached: see \c mbedtls_ecp_set_max_ops().
Notes
Performs the same job as \c mbedtls_pk_sign(), but can return early and restart according to the limit set with \c mbedtls_ecp_set_max_ops() to reduce blocking for ECC operations. For RSA, same as \c mbedtls_pk_sign().
