130.It Fl a Ar LEVEL | Fl \-anonymity= Ns Ar LEVEL
131This option can be used to specify additional anonymity constraints. The default is 1.
132If set to 0, GNUnet will publish the file non-anonymously and in fact sign the advertisement for the file using your peer's private key.
133This will allow other users to download the file as fast as possible, including using non-anonymous methods (discovery via DHT and CADET transfer).
134If you set it to 1 (default), you use the standard anonymous routing algorithm (which does not explicitly leak your identity).
135However, a powerful adversary may still be able to perform traffic analysis (statistics) to over time discovery your identity.
136You can gain better privacy by specifying a higher level of anonymity (using values above 1).
137This tells FS that it must hide your own requests in equivalent\-looking cover traffic.
138This should confound an adversaries traffic analysis, increasing the time and effort it would
139take to discover your identity. However, it also can significantly reduce performance, as
140your requests will be delayed until sufficient cover traffic is available. The specific
141numeric value (for anonymity levels above 1) is simple:
142Given an anonymity level L (above 1), each request FS makes on your behalf must be hidden in L\-1 equivalent
143requests of cover traffic (traffic your peer routes for others) in the same time\-period.
144The time\-period is twice the average delay by which GNUnet artificially delays traffic.
145Note that regardless of the anonymity level you choose, peers that cache content in the
146network always use anonymity level 1.

200The \fB\-a\fR option can be used to specify additional anonymity constraints.
201If set to 0, GNUnet will publish the file non-anonymously and in fact sign the advertisement for the file using your peer's private key.
202This will allow other users to download the file as fast as possible, including using non-anonymous methods (DHT, direct transfer).
203If you set it to 1 (default), you use the standard anonymous routing algorithm (which does not explicitly leak your identity).
204However, a powerful adversary may still be able to perform traffic analysis (statistics) to over time infer data about your identity.
205You can gain better privacy by specifying a higher level of anonymity, which increases the amount of cover traffic your own traffic will get, at the expense of performance.
206Note that regardless of the anonymity level you choose, peers that cache content in the network always use anonymity level 1.
207.Pp
208The definition of the ANONYMITY LEVEL is the following.
2090 means no anonymity is required.
210Otherwise a value of 'v' means that 1 out of v bytes of "anonymous" traffic can be from the local user, leaving 'v-1' bytes of cover traffic per byte on the wire.
211Thus, if GNUnet routes n bytes of messages from foreign peers (using anonymous routing), it may originate n/(v-1) bytes of data in the same time\-period.
212The time\-period is twice the average delay that GNUnet defers forwarded queries.
213.Pp
214The default is 1 and this should be fine for most users.
215Also notice that if you choose very large values, you may end up having no throughput at all, especially if many of your fellow GNUnet\-peers all do the same.
