The only valid application type

Functions

func ExtractRootHash

func ExtractRootHash(gossipSTH Gossip_object) ([]byte, error)

func TypeString

func TypeString(t string) string

This function prints the "name string" of each Gossip object type. It's used when printing this info to console.

func Verify_CON

func Verify_CON(g Gossip_object, c *crypto.CryptoConfig) error

func Verify_PayloadFrag

func Verify_PayloadFrag(g Gossip_object, c *crypto.CryptoConfig) error

verifies signature fragments match with payload

func Verify_PayloadThreshold

func Verify_PayloadThreshold(g Gossip_object, c *crypto.CryptoConfig) error

verifies threshold signatures match payload

func Verify_RSAPayload

func Verify_RSAPayload(g Gossip_object, c *crypto.CryptoConfig) error

Verifies RSAsig matches payload, wait.... i think this just works out of the box with what we have

Types

}

func (Gossip_ID) String

func (g Gossip_ID) String() string

type Gossip_Storage

type Gossip_Storage map[Gossip_ID]Gossip_object

type Gossip_object

type Gossip_object struct {
	Application string    `json:"application"`
	Period      string    `json:"period"`

	Signer    string
	Timestamp string
	Period    string
	RootHash  string
	TreeSize  int
}
