type VRF 

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

The VRF keystore tracks auxiliary VRF secret keys, and generates their VRF proofs

VRF proofs need access to the actual secret key, which geth does not expose. Similar to the way geth's KeyStore exposes signing capability, VRF exposes VRF proof generation without the caller needing explicit knowledge of the secret key.

func (*VRF) Archive 

func (ks *VRF) Archive(key secp256k1.PublicKey) (err error)

func (ks *VRF) CreateAndUnlockWeakInMemoryEncryptedKeyXXXTestingOnly(phrase string) (*vrfkey.EncryptedVRFKey, error)

CreateAndUnlockWeakInMemoryEncryptedKeyXXXTestingOnly is for testing only! It returns an encrypted key which is fast to unlock, but correspondingly easy to brute force. It is not persisted to the DB, because no one should be keeping such keys lying around.

func (*VRF) CreateKey 

func (ks *VRF) CreateKey(phrase string) (secp256k1.PublicKey, error)

CreateKey returns a public key which is immediately unlocked in memory, and saved in DB encrypted with phrase. If p is given, its parameters are used for key derivation from the phrase.

func (*VRF) Delete 

func (ks *VRF) Delete(key secp256k1.PublicKey) (err error)

Delete removes keys with this public key from the keystore and the DB, if present.

func (*VRF) Forget

func (*VRF) GenerateProof 

func (ks *VRF) GenerateProof(k secp256k1.PublicKey, seed *big.Int) (
	vrfkey.Proof, error)

GenerateProof is marshaled randomness proof given k and VRF input seed computed from the SeedData

Key must have already been unlocked in ks, as constructing the VRF proof requires the secret key.

func (*VRF) Get 

func (ks *VRF) Get(k ...secp256k1.PublicKey) ([]*vrfkey.EncryptedVRFKey, error)

Get retrieves all vrfkey.EncryptedVRFKey's associated with k, or all encrypted keys if k is nil, or errors

func (*VRF) GetSpecificKey 

func (ks *VRF) GetSpecificKey(
	k secp256k1.PublicKey) (*vrfkey.EncryptedVRFKey, error)

func (*VRF) Import 

func (ks *VRF) Import(keyjson []byte, auth string) error

Import adds this encrypted key to the DB and unlocks it in in-memory store with passphrase auth, and returns any resulting errors

func (*VRF) ListKeys 

func (ks *VRF) ListKeys() (publicKeys []*secp256k1.PublicKey, err error)

ListKeys lists the public keys contained in the db

func (*VRF) Store 

func (ks *VRF) Store(key *vrfkey.PrivateKey, phrase string, scryptParams utils.ScryptParams) error

Store saves key to ks (in memory), and to the DB, encrypted with phrase

func (*VRF) StoreInMemoryXXXTestingOnly 

func (ks *VRF) StoreInMemoryXXXTestingOnly(key *vrfkey.PrivateKey)

StoreInMemoryXXXTestingOnly memorizes key, only in in-memory store.

func (*VRF) Unlock 

func (ks *VRF) Unlock(phrase string) (keysUnlocked []secp256k1.PublicKey,
	merr error)

Unlock tries to unlock each vrf key in the db, using the given pass phrase, and returns any keys it manages to unlock, and any errors which result.

type VRFORM 

type VRFORM interface {
	FirstOrCreateEncryptedSecretVRFKey(k *vrfkey.EncryptedVRFKey) error
	ArchiveEncryptedSecretVRFKey(k *vrfkey.EncryptedVRFKey) error
	DeleteEncryptedSecretVRFKey(k *vrfkey.EncryptedVRFKey) error
	FindEncryptedSecretVRFKeys(where ...vrfkey.EncryptedVRFKey) ([]*vrfkey.EncryptedVRFKey, error)
}
