Public Methods

Method	Description
Create ( AuthenticationTicketData ticketData, string secret, bool encode = false ) : string	Creates a Base64-encoded ticket based on the provided data. The ticket is created using the mod_auth_tkt algorithm.
Create ( string userId, string userData, string tokens, System.DateTime timeStamp, string secret, bool encode = false, string ipAddress = AuthenticationTicketData.DefaultIPAddress, string version = AuthenticationTicketData.DefaultVersion ) : string	Creates a Base64-encoded ticket based on the provided data. The ticket is created using the mod_auth_tkt algorithm.
ExtractData ( string ticket, string secret = null, bool encoded = false, string ipAddress = AuthenticationTicketData.DefaultIPAddress ) : AuthenticationTicketData	Extracts the data from a provided ticket.
Validate ( string ticket, string secret, bool encoded = false, string ipAddress = AuthenticationTicketData.DefaultIPAddress, string version = AuthenticationTicketData.DefaultVersion ) : bool	Validates a ticket based on the provided data.

Private Methods

Method	Description
CreateDigest ( AuthenticationTicketData ticketData, string secret ) : string	Creates the digest portion of the ticket from the provided data. The algorithm for the digest is as follows: digest = MD5(digest0 + key) where Version 1.3: digest0 = MD5(iptstamp + key + user_id + user_data) Version 2.0: digest0 = MD5(iptstamp + key + user_id + '\0' + token_list + '\0' + user_data)
CreateIPTimeStamp ( uint ipAddress, uint timestamp ) : string	Creates the IP Address / Timestamp byte array used in the digest. IPTStamp is a 8 bytes long byte array, bytes 0-3 are filled with client's IP address as a binary number in network byte order, bytes 4-7 are filled with timestamp as a binary number in network byte order.
Decode ( string data, string secret, uint timestamp, int offset ) : string	Decodes a data string.
Encode ( string data, string secret, uint timestamp, int offset ) : string	Encodes a data string.
GetDecodeIndex ( int a, int b, int c ) : int	Gets the index in the decoded character string by solving for x in the equation: (x + a) % b = c where x is between 0 and b
Parse ( string ticket ) : AuthenticationTicketData	Parses the decoded ticket. The expected format of the ticket is: digest (32 chars) + hex timestamp (8 chars) + user ID + '!' + user data OR digest (32 chars) + hex timestamp (8 chars) + user ID + '!' + tokens + '!' user data

Method Details

Create() public static method

Creates a Base64-encoded ticket based on the provided data.

The ticket is created using the mod_auth_tkt algorithm.

public static Create ( AuthenticationTicketData ticketData, string secret, bool encode = false ) : string
ticketData	AuthenticationTicketData	Data used to create the ticket.
secret	string	Secret key used to create the ticket.
encode	bool	True if the user id, user data, and tokens are to be encoded; false otherwise
return	string

Create() public static method

encode	bool	True if the user id, user data, and tokens are to be encoded; false otherwise
ipAddress	string	IP Address
version	string	Version of the mod_auth_tkt algorithm used to create the ticket
return	string

ExtractData() public static method

Extracts the data from a provided ticket.
