Once you have enabled the elliptic curve algorithms, you can change the order of the list using the red up and down arrow buttons. Tectia Client reads the list in the top-down order. The list will look like this if the ECDSA algorithms are ordered at the top:
To enable ECDSA keys for X.509, repeat the process above but select the keys named x509v3-ecdsa-sha2-* instead.
Creating ECDSA User Key
In the Tectia Connections Configuration GUI, go to User Authentication > Keys and Certificates. Under Key and Certificate List, click New key....
Provide a file name for the key.
Click Advanced Options.
For Key type, select ECDSA.
Select the Key length. A 256-bit ECDSA key provides a level of security equivalent to a 3072-bit DSA or RSA key.

To generate the key, click Next.
The wizard takes you to the Upload Public Key page. If you do not wish to upload the key to a server, click Cancel.
