"**Third parties don't have access to anything that happens in "
"OnionShare.** Using OnionShare means hosting services directly on your "
"computer. When sharing files with OnionShare, they are not uploaded to "
"any server. If you make an OnionShare chat room, your computer acts as a "
"server for that too. This avoids the traditional model of having to trust"
" the computers of others."

"**Network eavesdroppers can't spy on anything that happens in OnionShare "
"in transit.** The connection between the Tor onion service and Tor "
"Browser is end-to-end encrypted. This means network attackers can't "
"eavesdrop on anything except encrypted Tor traffic. Even if an "
"eavesdropper is a malicious rendezvous node used to connect the Tor "
"Browser with OnionShare's onion service, the traffic is encrypted using "
"the onion service's private key."

"**Anonymity of OnionShare users are protected by Tor.** OnionShare and "
"Tor Browser protect the anonymity of the users. As long as the OnionShare"
" user anonymously communicates the OnionShare address with the Tor "
"Browser users, the Tor Browser users and eavesdroppers can't learn the "
"identity of the OnionShare user."

"**If an attacker learns about the onion service, it still can't access "

"services allowed the attacker to discover private .onion addresses. If an"
" attack discovers a private OnionShare address, a password will be "
"prevent them from accessing it (unless the OnionShare user chooses to "
"turn it off and make it public). The password is generated by choosing "
"two random words from a list of 6800 words, making 6800², or about 46 "
"million possible passwords. Only 20 wrong guesses can be made before "
"OnionShare stops the server, preventing brute force attacks against the "
"password."

"**Communicating the OnionShare address might not be secure.** "
"Communicating the OnionShare address to people is the responsibility of "
"the OnionShare user. If sent insecurely (such as through an email message"
" monitored by an attacker), an eavesdropper can tell that OnionShare is "
"being used. If the eavesdropper loads the address in Tor Browser while "
"the service is still up, they can access it. To avoid this, the address "
"must be communicateed securely, via encrypted text message (probably with"
" disappearing messages enabled), encrypted email, or in person. This "
"isn't necessary when using OnionShare for something that isn't secret."

"**Communicating the OnionShare address might not be anonymous.** Extra "
"precautions must be taken to ensure the OnionShare address is "
"communicated anonymously. A new email or chat account, only accessed over"
" Tor, can be used to share the address. This isn't necessary unless "
"anonymity is a goal."
