can this guide be used on Nitrokey Storage 2? If so, I would buy one.

"Update 20.11.2017: With GnuPG 2.2.2 and higher, during "generate" command you can enter the keysize "25519" to select Curve25519. In this case you can skip the following lines.) However it is not as yet possible to select the type of key directly, so the key must first be prepared."

Fill in the blank.
