Types

type CSP

type CSP interface {
	NewRSAKeys() (publicKey []byte, privateKey []byte, e error)
	NewECDSAKeys() (publicKey []byte, privateKey []byte, e error)
	VerifyMessage(publicKey []byte, message []byte, signature []byte) error
	NewSymmetricKey() ([]byte, error)
	SignMessage(privateKey []byte, message []byte) (signature []byte, e error)
	PkDecryptMessage(privateKey []byte, encryptedMessage []byte) (message []byte, e error)
	PkEncryptMessage(publicKey []byte, message []byte) ([]byte, error)
	DecryptMessage(key []byte, encryptedMessage []byte) ([]byte, error)
	EncryptMessage(key []byte, message []byte) (encryptedMessage []byte, e error)
}

CSP (Crypto Service Provider) offers a high-level abstract of cryptographic primitives used in FPC

func GetDefaultCSP

func GetDefaultCSP() CSP

type EncryptionContext

type EncryptionContext interface {
	Conceal(function string, args []string) (string, error)
	Reveal(r []byte) ([]byte, error)
}

EncryptionContext defines the interface of an object responsible to encrypt the contents of a transaction invocation and to decrypt the corresponding response. Conceal and Reveal must be called only once during the lifetime of an object that implements this interface. That is, an EncryptionContext is only valid for a single transaction invocation.

type EncryptionContextImpl

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

func (*EncryptionContextImpl) Conceal

func (e *EncryptionContextImpl) Conceal(function string, args []string) (string, error)

func (*EncryptionContextImpl) Reveal

func (e *EncryptionContextImpl) Reveal(signedResponseBytesB64 []byte) ([]byte, error)

type EncryptionProvider

type EncryptionProvider interface {
	NewEncryptionContext() (EncryptionContext, error)
}

type EncryptionProviderImpl

type EncryptionProviderImpl struct {
	CSP                CSP
	GetCcEncryptionKey func() ([]byte, error)
}

func (EncryptionProviderImpl) NewEncryptionContext

func (p EncryptionProviderImpl) NewEncryptionContext() (EncryptionContext, error)
