Help for Cookie PW data

Hey guys,
I want to know a thing about the cookies:

I know that the PW is stored in the cookies, the name of it is always tpass_nameofbrute.
The content is something crazy.
Now I want to test if the content of the cookie belongs to anything of the brute.
So I created one brute (very hard ) and here are the datas of him:

Name:pwencrypttest
GFX:0;0;80;94;30;21;56;23;0;96;75;0;91;95;77;71
Level: 1
Cookie Name: tpass_pwencrypttest
Cookie Content: 2OxdWLl8DIQkdxngaU9y9YSy6VRYdoaB


#Note: Please dont fight with him
