Digital Signing

The signing process requires a security key pair and a signing tool to sign the image. The private and public key pair are generated based on a 256 bit ECDSA asymmetric digital signature. The private key has full entropy and is used to derive the public key.

The signing process creates a digital certificate with signatures based on elliptic curve cryptography. The credentials of the signed image during authentication are the digital signature and the public key.
