Various license types

Functions

func New

func New() (string, string)

New generates a new license and master key. This uses the most up-to-date version of the license to generate a new one.

Types

type Cipher

type Cipher interface {
	DecryptKey(buffer []byte) (security.Key, error)
	EncryptKey(k security.Key) (string, error)
}

Cipher represents a cipher used by the license type.

type License

type License interface {
	fmt.Stringer
	NewMasterKey(id uint16) (security.Key, error)
	Cipher() (Cipher, error)
	Contract() uint32
	Signature() uint32
	Master() uint32
}

License represents an abstract license.

func Parse

func Parse(data string) (License, error)

Parse parses a valid license of any version.

type V1

type V1 struct {
	EncryptionKey string    // Gets or sets the encryption key.
	User          uint32    // Gets or sets the contract id.
	Sign          uint32    // Gets or sets the signature of the contract.
	Expires       time.Time // Gets or sets the expiration date for the license.
	Type          uint32    // Gets or sets the license type.
}

V1 represents a legacy v1 license.

func NewV1

func NewV1() *V1

NewV1 generates a new legacy v1 license.

func (*V1) Cipher

func (l *V1) Cipher() (Cipher, error)

Cipher creates a new cipher for the licence

func (*V1) Contract

func (l *V1) Contract() uint32

Contract returns the contract ID of the license.

func (*V1) Master

func (l *V1) Master() uint32

Master returns the secret key index.

func (*V1) NewMasterKey

func (l *V1) NewMasterKey(id uint16) (key security.Key, err error)

NewMasterKey generates a new master key.

func (*V1) Signature

func (l *V1) Signature() uint32

Signature returns the signature of the license.

func (*V1) String

func (l *V1) String() string

String converts the license to string.

type V2

type V2 struct {
	EncryptionKey  []byte // Gets or sets the encryption key.
	EncryptionSalt []byte // Gets or sets the encryption key.
	User           uint32 // Gets or sets the contract id.
	Sign           uint32 // Gets or sets the signature of the contract.
	Index          uint32 // Gets or sets the current master.
}

V2 represents a v2 license.

func NewV2

func NewV2() *V2

NewV2 generates a new v2 license.

func (*V2) Cipher

func (l *V2) Cipher() (Cipher, error)

Cipher creates a new cipher for the licence

func (*V2) Contract

func (l *V2) Contract() uint32

Contract returns the contract ID of the license.

func (*V2) Master

func (l *V2) Master() uint32

Master returns the secret key index.

func (*V2) NewMasterKey

func (l *V2) NewMasterKey(id uint16) (key security.Key, err error)

func (*V2) Signature

func (l *V2) Signature() uint32

Signature returns the signature of the license.

func (*V2) String

func (l *V2) String() string

String converts the license to string.

type V3

type V3 struct {
	EncryptionKey  []byte // Gets or sets the encryption key.
	EncryptionSalt []byte // Gets or sets the encryption key.
	User           uint32 // Gets or sets the contract id.
	Sign           uint32 // Gets or sets the signature of the contract.
	Index          uint32 // Gets or sets the current master.
}
