OnionShare – an open source tool that lets you securely and anonymously share files, host websites, and chat with friends using the Tor network.

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 anything. Prior attacks against the Tor network to enumerate onion 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 communicated 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.

Ricochet IM (previously: Torsion IM) – an instant messaging software project developed by John Brooks and later by Invisible.im group.

Ricochet is a different approach to instant messaging that doesn’t trust anyone in protecting your privacy.
– Eliminate metadata. Nobody knows who you are, who you talk to, or what you say.
– Stay anonymous. Share what you want, without sharing your identity and location.
– Nobody in the middle. There are no servers to monitor, censor, or hack.
– Safe by default. Security isn’t secure until it’s automatic and easy to use.

Ricochet uses the Tor network to reach your contacts without relying on messaging servers. It creates a hidden service, which is used to rendezvous with your contacts without revealing your location or IP address. Everything is encrypted end-to-end, so only the intended recipient can decrypt it, and anonymized, so nobody knows where it’s going and where it came from.

Ricochet is an experiment. Security and anonymity are difficult topics, and you should carefully evaluate your risks and exposure with any software.

The latest version 1.1.4 was released November 2016.

ProtonMail – an encrypted e-mail service, which doesn’t let read messages by people other than a recipient and a sender.

ProtonMail is the world’s largest provider of encrypted email service with over a million users. The ProtonMail secure email application for Android allows you to easily send encrypted messages from your mobile device thanks to the integration of PGP end-to-end encryption. ProtonMail uses a modern user interface with a set of innovative features such as individual gestures on a screen and ability to send messages with a set date of removal.

From 2013, when CERN scientists founded ProtonMail, we (developers) were joined by citizens from around the world who support our mission to protect privacy on the web. Our mobile application was built thanks to a record campaign in which we raised $ 550,000. With the ProtonMail app, you can now create a free account with the ProtonMail inbox and start using a secure future box.

The notable features are:
– Messages are stored on ProtonMail servers in encrypted format. They are also transmitted in encrypted format between our servers and user devices.
– ProtonMail’s zero access architecture means that your data is encrypted in a way that makes it inaccessible to us. Data is encrypted on the client side using an encryption key that we do not have access to.
– We use only secure implementations of AES, RSA, along with OpenPGP. Furthermore, all of the cryptographic libraries we use are open source. By using open source libraries, we can guarantee that the encryption algorithms we are using do not have clandestinely built in back doors.
