The value used to specify the storage location.
public int DataTag { get; set; }Property Value
| Type | Description |
|---|---|
| System.Int32 |
Remarks
Where, on the YubiKey, data is stored is determined by the
DataTag. It is a number such as 0x005fC102 or
0x005FFF00.
There are some tag values defined by the PIV standard, and there are
others defined by Yubico (see the User's Manual entry on
GET DATA and
GET vendor data).
In addition, some numbers are accepted by a YubiKey even though no
one has defined their use or contents. These are the numbers
0x005F0000 through 0x005FFFFF (inclusive) not already
specified.
When you instantiate an object that is a subclass of this abstract
class, this property will be set with the defined (or sometimes it's
called the default) DataTag. However, it is possible to change
that tag. See the User's manual entry on
PIV data objects
for more information on what valid data tags are possible. If you try
to change to an unsupported tag, the SDK will throw an exception.
Note that changing the DataTag is not recommended, but it is
possible because there are some applications that have a use case for
such a feature. See the User's Manual entry on
PIV data objects.
