Three different signing keys


I have to sign three different images. Therefore, I need 3 different RSA-4096.
Is it possible to store 3 different private RSA-4096 keys in the Nitrokey and use them all for signing?

Is it also possible to import them into the key? Is it also possible to generate them with the Nitrokey and export them and import them into another Nitrokey?

Best regards

Dear Gerd,

The Nitrokey HSM is actually a SmartCard-HSM. So what applies for the SmartCard-HSM is also true for the Nitrokey HSM.



As @sc-hsm has mentioned, for this use case Nitrokey HSM2 should work best. It supports the features are you asking for. More information:
