Supported signature types by AWS KMS

const ProviderName = "AWSKMS"

ProviderName specifies a provider name

Variables

var KmsClientFactory = func(p client.ConfigProvider, cfgs ...*aws.Config) (KmsClient, error) {
	return kms.New(p, cfgs...), nil
}

KmsClientFactory override for unittest

Functions

func KmsLoader

func KmsLoader(tc cryptoprov.TokenConfig) (cryptoprov.Provider, error)

KmsLoader provides loader for KMS provider

func NewSigner

func NewSigner(keyID string, label string, signingAlgorithms []string, publicKey crypto.PublicKey, kmsClient KmsClient) crypto.Signer

NewSigner creates new signer

Types

type KmsClient

type KmsClient interface {
	CreateKey(input *kms.CreateKeyInput) (*kms.CreateKeyOutput, error)
	//IdentifyKey(priv crypto.PrivateKey) (keyID, label string, err error)
	ListKeys(options *kms.ListKeysInput) (*kms.ListKeysOutput, error)
	ScheduleKeyDeletion(input *kms.ScheduleKeyDeletionInput) (*kms.ScheduleKeyDeletionOutput, error)
	DescribeKey(input *kms.DescribeKeyInput) (*kms.DescribeKeyOutput, error)
	GetPublicKey(input *kms.GetPublicKeyInput) (*kms.GetPublicKeyOutput, error)
	Sign(input *kms.SignInput) (*kms.SignOutput, error)
}

KmsClient interface

type Provider

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

Provider implements Provider interface for KMS

func Init

func Init(tc cryptoprov.TokenConfig) (*Provider, error)

Init configures Kms based hsm impl

func (*Provider) Close

func (p *Provider) Close() error

Close allocated resources and file reloader

func (*Provider) CurrentSlotID

func (p *Provider) CurrentSlotID() uint

CurrentSlotID returns current slot id. For KMS only one slot is assumed to be available.

func (*Provider) DestroyKeyPairOnSlot

func (p *Provider) DestroyKeyPairOnSlot(slotID uint, keyID string) error

DestroyKeyPairOnSlot destroys key pair on slot. For KMS slotID is ignored and KMS retire API is used to destroy the key.

func (*Provider) EnumKeys

func (p *Provider) EnumKeys(slotID uint, prefix string) ([]cryptoprov.KeyInfo, error)

EnumKeys returns list of keys on the slot. For KMS slotID is ignored.

func (*Provider) EnumTokens

func (p *Provider) EnumTokens(currentSlotOnly bool) ([]cryptoprov.TokenInfo, error)

EnumTokens lists tokens. For KMS currentSlotOnly is ignored and only one slot is assumed to be available.

func (*Provider) ExportKey

func (p *Provider) ExportKey(keyID string) (string, []byte, error)

ExportKey returns PKCS#11 URI for specified key ID. It does not return key bytes

func (*Provider) FindKeyPairOnSlot

func (p *Provider) FindKeyPairOnSlot(slotID uint, keyID, label string) (crypto.PrivateKey, error)

FindKeyPairOnSlot retrieves a previously created asymmetric key, using a specified slot.

func (*Provider) GenerateECDSAKey

func (p *Provider) GenerateECDSAKey(label string, curve elliptic.Curve) (crypto.PrivateKey, error)

GenerateECDSAKey creates signer using randomly generated ECDSA key

func (*Provider) GenerateRSAKey

func (p *Provider) GenerateRSAKey(label string, bits int, purpose int) (crypto.PrivateKey, error)

GenerateRSAKey creates signer using randomly generated RSA key

func (*Provider) GetKey

func (p *Provider) GetKey(keyID string) (crypto.PrivateKey, error)

GetKey returns pkcs11 uri for the given key id

func (*Provider) IdentifyKey

func (p *Provider) IdentifyKey(priv crypto.PrivateKey) (keyID, label string, err error)

IdentifyKey returns key id and label for the given private key

func (*Provider) KeyInfo
