Make sure that you created a user who can manage crypto operations (CryptoUser). The byoktool supports all key types (PKCS#11, CNG, JCE, CXI). In this guide we will create a PKCS#11 key. For other types, please refer to the documentation provided to you on the Utimaco Product CD.
CMK must be an AES256 key!
The key will be stored in the internal key store of the HSM.
