How is the user hash built?
We generate a daily changing identifier in which we process the senders IP address once just to anonymize it. To anonymize this information, we use a hash function with a rotating salt. At no point of time it is possible for us (elbwalker) to decrypt this function and thus identify an individual user.
hash(salt + today + domain + userAgent + language + anonymizedIp)
