| 15 | 4 | Andreas Steffen | You can create an ECDSA key with the _openssl ecparam_ command. |
| 16 | 4 | Andreas Steffen | <pre> |
| 17 | 1 | Andreas Steffen | openssl ecparam -list_curves |
| 18 | 4 | Andreas Steffen | </pre> |
| 19 | 1 | Andreas Steffen | gives you a huge list of available elliptic curves but IKEv2 currently supports |
| 20 | 1 | Andreas Steffen | only the following three curves: |
| 21 | 4 | Andreas Steffen | <pre> |
| 22 | 1 | Andreas Steffen | prime256v1 |
| 23 | 1 | Andreas Steffen | secp384r1 |
| 24 | 1 | Andreas Steffen | secp521r1 |
| 25 | 4 | Andreas Steffen | </pre> |
| 26 | 1 | Andreas Steffen | The creation of an EC key goes like this: |
| 27 | 4 | Andreas Steffen | <pre> |
| 28 | 2 | Andreas Steffen | openssl ecparam -genkey -name secp384r1 -noout -out ecKey.pem |
| 29 | 4 | Andreas Steffen | </pre> |
| 30 | 1 | Andreas Steffen | Verify the content of the key: |
| 31 | 4 | Andreas Steffen | <pre> |
| 32 | 1 | Andreas Steffen | openssl ec -in ecKey.pem -text |
