aspxauth

Provides utilities to assist in generating, validating and decrypting .NET authorization tickets (usually set in the .ASPXAUTH cookie) for interoperation with .NET authentication.

Setup

The module must be initialized with configuration that corresponds to your .NET configuration and the machine key used to generate the auth ticket.

• validationMethod (string): (default "sha1")
• validationKey (string): hex encoded key to use for signature validation
• decryptionMethod (string): (default "aes")
• decryptionIV (string): hex encoded initialization vector (defaults to a vector of zeros)
• decryptionKey (string): hex encoded key to use for decryption
• ticketVersion (integer): if specified then will be used to validate the ticket version
• validateExpiration (bool): (default true) if false then decrypted tickets will be returned even if past their expiration
• encryptAsBuffer (bool): (default false) if true, encrypt will return a buffer rather than a hex encoded string
• defaultTTL (integer): (default 24hrs) if provided is used as milliseconds from issueDate to expire generated tickets
• defaultPersistent (bool): (default false) if provided is used as default isPersistent value for generated tickets
• defaultCookiePath (string): (default "/") if provided is used as default cookiePath for generated tickets

// Configure
var aspxauth = require( "aspxauth" )( {
    validationMethod: "sha1",
    validationKey: process.env.DOTNET_VALIDATION_KEY,
    decryptionMethod: "aes",
    decryptionIV: process.env.DOTNET_DECRYPTION_IV,
    decryptionKey: process.env.DOTNET_DECRYPTION_KEY
} );

// Generate encrypted cookie
var encryptedCookieValue = aspxauth.encrypt( {
    name: "some.username@place.com",
    customData: "other data"
} );

// Decrypt an existing cookie
var authTicket = aspxauth.decrypt( req.cookies[ ".ASPXAUTH" ] );
