README

EtherKeyMS is a library for Ethereum operation with the Key Management Service (KMS) from the Google Cloud Platform (GCP). Better leave those keys in secured place. 😏

This is free and unencumbered software released into the public domain.

Your feedback and code is welcome.

Types

type ManagedKey

type ManagedKey struct {
	// KMS uses a slash-separated path for identification.
	// This field is read-only.
	KeyName string
	// Each (public) key maps to one address on the blockchain.
	// This field is read-only.
	EthereumAddr common.Address
	// contains filtered or unexported fields
}

ManagedKey represents a key from the Key Management Service (KMS).

func NewManagedKey

func NewManagedKey(ctx context.Context, client *kms.KeyManagementClient, keyName string) (*ManagedKey, error)

NewManagedKey executes a fail-fast initialization. Key names from the Google cloud are slash-separated paths.

func (*ManagedKey) NewEthereumSigner

func (mk *ManagedKey) NewEthereumSigner(ctx context.Context, txIdentification types.Signer) bind.SignerFn

NewEthereumSigner returns a KMS-backed instance. Ctx applies to the entire lifespan of the bind.SignerFn.

func (*ManagedKey) NewEthereumTransactor

func (mk *ManagedKey) NewEthereumTransactor(ctx context.Context, txIdentification types.Signer) *bind.TransactOpts

NewEthereumTransactor returns a KMS-backed instance. Ctx applies to the entire lifespan of the bind.TransactOpts.

func (*ManagedKey) SignHash

func (mk *ManagedKey) SignHash(ctx context.Context, hash common.Hash) ([]byte, error)

SignHash returns the signature bytes.
