end-to-end - End-To-End is a crypto library to encrypt, decrypt, digital sign, and verify signed messages (implementing OpenPGP and OTR)

•    Javascript

---

End-To-End is a crypto library to encrypt, decrypt, digital sign, and verify signed messages (implementing OpenPGP and OTR).This is the source code for the End-To-End library. It's built upon a newly developed, JavaScript-based crypto library. End-To-End implements the OpenPGP standard, IETF RFC 4880, enabling key generation, encryption, decryption, digital signature, and signature verification.

coyim - coyim - a safe and secure chat client

•    Go

---

CoyIM is a new client for the XMPP protocol. It is built upon https://github.com/agl/xmpp-client and https://github.com/coyim/otr3. It adds a graphical user interface and implies safe and secure options by default. Our ambition is that it should be possible for even the most high-risk people on the planet to safely use CoyIM, without having to make any configuration changes. To do this, CoyIM has OTR enabled and uses Tor by default. Besides that, it will only use the Tor Onion Service for a known server and also uses TLS and TLS certificates to verify the connection - no configuration required. The implementation is written in the Go language, to avoid many common types of vulnerabilities that come from using unsafe languages.

otrtalk - OTR p2p chat

•    Javascript

---

OTRTALK is a command line based chat application. Unlike most instant messenger applications it doesn't rely on centralised servers. Instead it utilises a DHT (Distributed Hash Table) similar to BitTorrent, called telehash. There is also experimental support for discovery of buddies over mainline BitTorrent DHT network. Other discovery protocols will be added in future, with more focus towards privacy preserving protocols.

otr4j - Off-The-Record messaging encryption written in pure Java

•    Java

---

otr4j is an implementation of the OTR (Off The Record) protocol in java. Off-the-Record Messaging, is a cryptographic protocol that uses a combination of the Advanced Encryption Standard (AES), the Diffie-Hellman key exchange, and the SHA hash functions. In addition to authentication and encryption, OTR provides perfect forward secrecy and malleable encryption. The OTR protocol was designed by Ian Goldberg and the OTR Development Team.

otrchat - 😈 An end-to-end encrypted chat system based on the OTR protocol

•    Go

---

An end-to-end encrypted chat system based on the OTR protocol. Off-the-Record Messaging (OTR) is a cryptographic protocol that provides encryption for instant messaging conversations. OTR uses a combination of AES symmetric-key algorithm with 128 bits key length, the Diffie–Hellman key exchange with 1536 bits group size, and the SHA-1 hash function. In addition to authentication and encryption, OTR provides forward secrecy and malleable encryption.
