type Key

type Key string

Key is key in PGP representation

func KeyFromUint64

func KeyFromUint64(key uint64) Key

KeyFromUint64 converts openpgp uint64 into hex human-readable

func (Key) Matches

func (key1 Key) Matches(key2 Key) bool

Matches checks two keys for equality

type KeyInfo

type KeyInfo struct {
	GoodKeys    []Key
	MissingKeys []Key
}

KeyInfo is response from signature verification

type Signer

type Signer interface {
	Init() error
	SetKey(keyRef string)
