Note: There are many variables, flags, and version-specific considerations for how .NET generates the .aspxauth cookie. This library works for our needs using older versions of the .NET framework. Your milage may vary.
Provides utilities to assist in generating, validating and decrypting .NET authorization tickets (usually set in the .ASPXAUTH cookie) for interoperation with .NET authentication.
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 validationdecryptionMethod(string): (default "aes")decryptionIV(string): hex encoded initialization vector (defaults to a vector of zeros)decryptionKey(string): hex encoded key to use for decryptionticketVersion(integer): if specified then will be used to validate the ticket versionvalidateExpiration(bool): (defaulttrue) if false then decrypted tickets will be returned even if past their expirationencryptAsBuffer(bool): (defaultfalse) if true, encrypt will return a buffer rather than a hex encoded stringdefaultTTL(integer): (default 24hrs) if provided is used as milliseconds fromissueDateto expire generated ticketsdefaultPersistent(bool): (defaultfalse) if provided is used as defaultisPersistentvalue for generated ticketsdefaultCookiePath(string): (default "/") if provided is used as defaultcookiePathfor generated ticketsmode(string): (default "dotnet45") if provided, it will try to decode as .net 4.5 compatible ticket, else specify "legacy"
