Functions

func AuthenticatedBytesToSign

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

Types

type Config

type Config struct {
	Policy       Policy
	Vaults       map[string]*config.VaultConfig
	Interceptor  SignInterceptor
	Watermark    watermark.Watermark
	Logger       log.FieldLogger
	VaultFactory vault.Factory
	PolicyHook   *PolicyHook
}

Config represents Signatory configuration

type Policy

type Policy = hashmap.PublicKeyHashMap[*PublicKeyPolicy]

func PreparePolicy

func PreparePolicy(src config.TezosConfig) (out Policy, err error)

PreparePolicy prepares policy data by hashing keys etc

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"`
	ClientKeyHash string `json:"client_key_hash,omitempty"`
	PublicKeyHash string `json:"public_key_hash"`
	Nonce         []byte `json:"nonce"`
}

type PublicKey

type PublicKey struct {
	vault.KeyReference
	Hash   crypt.PublicKeyHash
	Policy *PublicKeyPolicy
	Active bool
}

PublicKey contains public key with its hash

type PublicKeyPolicy

type PublicKeyPolicy struct {
	AllowedRequests     []string
	AllowedOps          []string
	LogPayloads         bool
	AuthorizedKeyHashes []crypt.PublicKeyHash
	AuthorizedJwtUsers  []string
}

PublicKeyPolicy contains policy data related to the key

type SignInterceptor

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

SignInterceptor is an observer function for signing request

type SignInterceptorOptions

type SignInterceptorOptions struct {
	Address crypt.PublicKeyHash
	Vault   string
	Req     string
	Stat    operationsStat
}

SignInterceptorOptions contains SignInterceptor arguments to avoid confusion

type SignRequest

type SignRequest struct {
	ClientPublicKeyHash crypt.PublicKeyHash // optional, see policy
	PublicKeyHash       crypt.PublicKeyHash
	Source              net.IP // optional caller address
	Message             []byte
}

SignRequest represents a sign request which may be authenticated with the client key

type Signatory

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

Signatory is a struct coordinate signatory action and select vault according to the key being used

func New

func New(ctx context.Context, c *Config) (*Signatory, error)

New returns Signatory instance

func (*Signatory) GetPublicKey

func (s *Signatory) GetPublicKey(ctx context.Context, keyHash crypt.PublicKeyHash) (*PublicKey, error)

GetPublicKey retrieve the public key from a vault

func (*Signatory) Import

func (s *Signatory) Import(ctx context.Context, importerName string, secretKey string, passCB func() ([]byte, error), opt utils.Options) (*PublicKey, error)

Import a keyPair inside the vault

func (*Signatory) ListPublicKeys

func (s *Signatory) ListPublicKeys(ctx context.Context) ([]*PublicKey, error)

ListPublicKeys retrieve the list of all public keys supported by the current configuration

func (*Signatory) Ready

func (s *Signatory) Ready(ctx context.Context) (bool, error)

Ready returns true if all backends are ready

func (*Signatory) Sign

func (s *Signatory) Sign(ctx context.Context, req *SignRequest) (crypt.Signature, error)

Sign ask the vault to sign a message with the private key associated to keyHash

func (*Signatory) Unlock

func (s *Signatory) Unlock(ctx context.Context) error

Unlock unlock all the vaults
