# Create ECDSA Keys

Creates a new Elliptic Curve Digital Signature Algorithm (ECDSA) public/private key pair.

In the diagram below, the keys are stored appropriately, where the private key will be used to sign data and the public key used to verify the signature.

## Properties

### Algorithm

Select which curve to use for the Elliptical Curve Digital Signature Algorithm (ECDSA).

Options:

* P-256
* P-384
* P-512

***

## Definition

The new public key and private key.

***

## Example

A simple usage scenario is where the private key is created and then stored in a database that is accessible only from the local machine, while the public key is stored in a file on a public network.
