Types

type HostKey

type HostKey struct {
	Private ed25519.PrivateKey
	Check   uint32
	Comment string
}

HostKey represents the private output of the following command:

ssh-keygen -t ed25519 -c "some comment"

func NewHostKey

func NewHostKey(rand io.Reader, comment string) (*HostKey, error)

NewHostKey generates a new host key in Ed25519 format

func (*HostKey) Fingerprint

func (hk *HostKey) Fingerprint() (string, error)

Fingerprint outputs a host key's SHA256 fingerprint

func (*HostKey) WriteEFI

func (hk *HostKey) WriteEFI(varUUID *uuid.UUID, name string) error

WriteEFI writes a host key to EFI-NVRAM in PEM format
