Types ¶
type AsymmetricKey ¶
type AsymmetricKey struct {
// contains filtered or unexported fields
}
AsymmetricKey - struct which encrypts/decrypts data using RSA public/private certificates
func NewAsymmetricKey ¶
func NewAsymmetricKey(privData []byte, pubData []byte) (*AsymmetricKey, error)
NewAsymmetricKey - generates a crypto module able to encrypt/decrypt data using a pair for private and public key
type CBCSecureMaterials ¶
type CBCSecureMaterials struct {
// contains filtered or unexported fields
}
CBCSecureMaterials encrypts/decrypts data using AES CBC algorithm
func NewCBCSecureMaterials ¶
func NewCBCSecureMaterials(key Key) (*CBCSecureMaterials, error)
NewCBCSecureMaterials builds new CBC crypter module with the specified encryption key (symmetric or asymmetric)
func (*CBCSecureMaterials) Close ¶
func (s *CBCSecureMaterials) Close() error
Close implements closes the internal stream.
func (*CBCSecureMaterials) GetDesc ¶
func (s *CBCSecureMaterials) GetDesc() string
GetDesc - user provided encryption material description in JSON (UTF8) format.
func (*CBCSecureMaterials) GetIV ¶
func (s *CBCSecureMaterials) GetIV() string
GetIV - return randomly generated IV (per S3 object), base64 encoded.
func (*CBCSecureMaterials) GetKey ¶
func (s *CBCSecureMaterials) GetKey() string
GetKey - return content encrypting key (cek) in encrypted form, base64 encoded.
func (*CBCSecureMaterials) Read ¶
func (s *CBCSecureMaterials) Read(buf []byte) (n int, err error)
Fill buf with encrypted/decrypted data
func (*CBCSecureMaterials) SetupDecryptMode ¶
SetupDecryptMode - tells CBC that we are going to decrypt data
func (*CBCSecureMaterials) SetupEncryptMode ¶
func (s *CBCSecureMaterials) SetupEncryptMode(stream io.Reader) error
SetupEncryptMode - tells CBC that we are going to encrypt data
type Key ¶
type Key interface { // Encrypt data using to the set encryption key Encrypt([]byte) ([]byte, error) // Decrypt data using to the set encryption key Decrypt([]byte) ([]byte, error) }
Key - generic interface to encrypt/decrypt a key. We use it to encrypt/decrypt content key which is the key that encrypt/decrypt object data.
type Materials ¶
type Materials interface { // Closes the wrapped stream properly, initiated by the caller. Close() error // Returns encrypted/decrypted data, io.Reader compatible. Read(b []byte) (int, error) // Get randomly generated IV, base64 encoded. GetIV() (iv string) // Get content encrypting key (cek) in encrypted form, base64 encoded. GetKey() (key string) // Get user provided encryption material description in // JSON (UTF8) format. This is not used, kept for future. GetDesc() (desc string) // Setup encrypt mode, further calls of Read() function // will return the encrypted form of data streamed // by the passed reader SetupEncryptMode(stream io.Reader) error // Setup decrypted mode, further calls of Read() function // will return the decrypted form of data streamed // by the passed reader SetupDecryptMode(stream io.Reader, iv string, key string) error }
Materials - provides generic interface to encrypt any stream of data.
type SymmetricKey ¶
type SymmetricKey struct {
// contains filtered or unexported fields
}
SymmetricKey - encrypts data with a symmetric master key
func NewSymmetricKey ¶
func NewSymmetricKey(b []byte) *SymmetricKey
NewSymmetricKey generates a new encrypt/decrypt crypto using an AES master key password
