Remarks

You can use the
feature lock
to choose which fields should be masked. On the activation method page, you can use the interactive table to choose which fields should be masked. FieldsToReturn will then get a new value, and this value should then be used in the
feature lock
.

Methods

AddDataObject(String, DataObject)

Creates a new DataObject.

Declaration
public long AddDataObject(string token, DataObject dataObject)
Parameters
Type Name Description
System.String token

The access token. Read more at https://app.cryptolens.io/docs/api/v3/Auth

DataObject dataObject

The data object to add to the license key.
Returns
Type Description
System.Int64

Returns the id of the data object (and updates the DataObjects) if successful, or -1 otherwise.
Remarks

Note: for more details, please see https://app.cryptolens.io/docs/api/v3/AddDataObject

AddFeature(String, Int32)

Gets the new version of this license from SKM. Note, you need to manually assign the new value to this object, eg, by license = license.Refresh("token");

Declaration
public bool AddFeature(string token, int feature)
Parameters
Type Name Description
System.String token

The access token. Read more at https://app.cryptolens.io/docs/api/v3/Auth

System.Int32 feature

The feature number, eg. 1,2,...,8.

Returns
Type Description
System.Boolean

Returns a true if successful and false otherwise.
Exceptions
Type Condition
System.ArgumentException

If the feature value is incorrect.

DaysLeft(Boolean)

Returns the number of days left for a given license (time left). This method is particularly useful when KeyInfo is not updated regularly, because TimeLeft will not be affected (stay constant). If your implementation checks the license with the server periodically, this method should be used instead of TimeLeft.

Declaration
public int DaysLeft(bool zeroIfExpired = false)
Parameters
Type Name Description
System.Boolean zeroIfExpired

If true, when a license has expired, zero will be returned.
Returns
Type Description
System.Int32

Equals(Object)

Declaration
public override bool Equals(object obj)
Parameters
Type Name Description
System.Object obj
Returns
Type Description
System.Boolean
Overrides
System.Object.Equals(System.Object)

FromResponse(String, RawResponse)

Creates a license key from a RawResponse object that can be obtained when calling .

Declaration
public static LicenseKey FromResponse(string RSAPubKey, RawResponse response)
Parameters
Type Name Description
System.String RSAPubKey
RawResponse response
Returns
Type Description
LicenseKey

Refresh(String)

Gets the new version of this license from SKM. By default, if the Signature field ís not null and not empty, SKM will sign the new data too. You can also require this explicitly by calling Refresh(String, Boolean), and setting the second parameter to 'true'.

Declaration
public bool Refresh(string token)
Parameters
Type Name Description
System.String token

The access token. Read more at https://app.cryptolens.io/docs/api/v3/Auth

Returns
Type Description
