var ErrInvalidKey = errors.New("crypto: invalid key for encryption. Must be even, odd, or both")
ErrInvalidKey is returned when the packet encryption is invalid
View Source
var ErrInvalidWrap = errors.New("crypto: the un/wrapped key has the wrong length")
ErrInvalidWrap is returned when the packet encryption indicates a different length of the wrapped key

Types ¶
type Crypto ¶
type Crypto interface {
// Generate generates an even or odd SEK.
GenerateSEK(key packet.PacketEncryption) error
// UnmarshalMK unwraps the key with the passphrase in a Key Material Extension Message. If the passphrase
// is wrong an error is returned.
UnmarshalKM(km *packet.CIFKeyMaterialExtension, passphrase string) error
// MarshalKM wraps the key with the passphrase and the odd/even SEK for a Key Material Extension Message.
MarshalKM(km *packet.CIFKeyMaterialExtension, passphrase string, key packet.PacketEncryption) error
// EncryptOrDecryptPayload encrypts or decrypts the data of a packet with an even or odd SEK and
// the sequence number.
EncryptOrDecryptPayload(data []byte, key packet.PacketEncryption, packetSequenceNumber uint32) error
}
Crypto implements the SRT data encryption and decryption.
