Gets or sets any extra data within the token that KeyMaster.NET will sign.
Declaration Syntax
Value
The extra data.
Remarks
By default, the signed items in a generated token are just a date-time stamp and a unique
sequence number. For enhanced security you can use the ExtraDataToSign property to additionally
set the username in the token; KeyMater.NET will then digitally sign the username. This protects
against external attempts to tamper with the token by modifying the username, since when Liberator
receives the token it will check that the user name and its decrypted signature match.
