Secure Token Grid Authentication 1.3

A bidimensional array of tokens of limited length, with letters and digits, is generated. The generated grid is seeded by a given secret salt string and a specific id that may be used to generate unique grids for different applications and users.

Secure Token Grid Authentication may also verify whether a token entered by the user corresponds to a token of a random grid position.

The grid tokens may also be formatted in an HTML table for presentation in Web pages. A sample PDF extended class is also provided to create PDF documents with included grid.
