Remarks

Notes to Implementers

When implementing in a derived class, consider using the following design: Add a private backing field to the class and have the get accessor of ClientHash return the value of a backing field. The constructor of the derived class should use the value of RequestTokenPrefix and an algorithm (and salt) known to the external application to create the hash value and assign it to a backing field.
