## NAME

rte\_crypto\_ecdsa\_op\_param

## SYNOPSIS

`#include <rte_crypto_asym.h>`

### Data Fields

enum **rte\_crypto\_asym\_op\_type** **op\_type**\
 **rte\_crypto\_param** **message**\
 **rte\_crypto\_uint** **k**\
 **rte\_crypto\_uint** **r**\
 **rte\_crypto\_uint** **s**\

## Detailed Description

ECDSA operation params

Definition at line **576** of file **rte\_crypto\_asym.h**.

## Field Documentation

### enum rte\_crypto\_asym\_op\_type op\_type

Signature generation or verification

Definition at line **577** of file **rte\_crypto\_asym.h**.

### rte\_crypto\_param message

Input message digest to be signed or verified

Definition at line **580** of file **rte\_crypto\_asym.h**.

### rte\_crypto\_uint k
