csrf_token

What is the purpose of this "csrf_token"

a:2:{s:10:"csrf_token";s:20:"7MCLP/s4A=ifwiBK.C8b";s:15:"csrf_token_time";i:1405137985;}

Is this like some kind of encryption...

I do remember the sys_session table being more viewable without this token...

csrf tokens are added to forms which is a new feature in dolphin which you can enable or disable in Settings->Advanced Settings->Security.

They are intended to protect the forms from cross site request forgery attacks.

Thanks that is very helpful...

but how do you make them work in forms?
