    		 Phishing attacks have been causing many victims that have their bank accounts robbed by crackers that steal their account passwords.

    Many banks are now giving their clients special cards with tables of token codes to increase the security and make it harder to steal accounts of phishing attack victims.

    This class provides a solution to generate token code tables from PHP, as well to validate the codes entered by a site user.

  • Detailed description:

    • This class can be used to generate a grid of tokens to authenticate users similar to those that banks provided to users to avoid account abuses after phishing attacks.

    It generates a bidimensional array of tokens of limited length with letters and digits.

    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.

    The class 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 (using the LGPL http://www.tcpdf.org library)
