Functions

func PreparePolicy

func PreparePolicy(src config.TezosConfig) (map[string]*Policy, error)

PreparePolicy prepares policy data by hashing keys etc

func SignRequestAuthenticatedBytes

func SignRequestAuthenticatedBytes(req *SignRequest) ([]byte, error)

Types

type Config

type Config struct {
	Policy       map[string]*Policy

type InMemoryWatermark struct {
	// contains filtered or unexported fields
}

InMemoryWatermark keep previous operation in memory

func (*InMemoryWatermark) IsSafeToSign

func (w *InMemoryWatermark) IsSafeToSign(pkh string, hash []byte, msg tezos.UnsignedMessage) error

IsSafeToSign return true if this msgID is safe to sign

type Policy

type Policy struct {
	AllowedRequests     []string
	AllowedOps          []string
	LogPayloads         bool
	AuthorizedKeyHashes []string
}

Policy contains policy data related to the key

type PolicyHook

type PolicyHook struct {
	Address string
	Auth    auth.AuthorizedKeysStorage
}

type PolicyHookReply

type PolicyHookReply struct {
	Payload   json.RawMessage `json:"payload"`
	Signature string          `json:"signature"`
}

type PolicyHookReplyPayload

type PolicyHookReplyPayload struct {
	Status        int    `json:"status"` // reflects the HTTP status
	Error         string `json:"error"`
	PublicKeyHash string `json:"public_key_hash"` // the key used to sign the reply
	Nonce         []byte `json:"nonce"`
}

type PolicyHookRequest

type PolicyHookRequest struct {
	Request       []byte `json:"request"`
	Source        net.IP `json:"source"`

}

type PublicKey

type PublicKey struct {
	PublicKey     string
	PublicKeyHash string
	VaultName     string
	ID            string
	Policy        *Policy
	Active        bool
}

PublicKey contains base58 encoded public key with its hash

type SignInterceptor

type SignInterceptor func(opt *SignInterceptorOptions, sing func() error) error

SignInterceptor is an observer function for signing request

type SignInterceptorOptions

type SignInterceptorOptions struct {

	Req     string
	Stat    tezos.OperationsStat
}

SignInterceptorOptions contains SignInterceptor arguments to avoid confusion

type SignRequest

type SignRequest struct {
