Unable to Decrypt the cookie

[nitinjs]

Hi,

I am getting following issue while decrypting:

An exception of type 'System.Web.HttpException' occurred in HttpCookieEncryption.dll but was not handled in user code

Additional information: Unable to Decrypt the cookie.

[nitinjs]

Inner exception says

Could not find any recognizable digits.

Can you please post reproduction steps or sample code? Your description isn't much help.

If you're using a webfarm (ie, multiple web servers load balanced) then make sure the machineKey is the same for all the webservers.

This library utilizes the same ASP.Net WebForms encryption/decryption mechanisms that protect ViewState. (Also if you change machineKey in between requests).

That could be why it can't decrypt.

Hi, I was having same problem, I was investigating and I found this issue open since 2018, just to be solved, what I did was remove the first two segments of the generated hex and with that if it performed the decryption correctly.

string hex = string.Join(string.Empty, oldHex.Skip(2)); on HexStringToByteArray function in MachineKeyWrapper Class
