| Private Chat

Communicate securely with your friends. Instant Perfect Forward Secrecy (IPFS): Symmetric and asymmetric end-to-end encryption with one click renewed. Instantly. Thats's "Cryptograpic Calling".

Message-Format-Example for 1:1-Chat:
RSA-SSL (AES (NTRU (Message))).

Hybrid Multi-Encryption. Open Source.
Echo Protocol: Adaptive Echo (AE). Half Echo. Full Echo.
Chat-Server Software included. Easy setup of an own chat server.

|Encrypted E-Mail

GoldBug is the first E-Mail-Client with Forward Secrecy for symm *and* a-symm encryption.

It supports POP3 and IMAP and also
p2p-Email with so called "virtual E-Mail Institutions". The data in this p2p e-mail-modus is then stored at your online-friends.
And: With the POPTASTIC function you even chat over E-Mail-Servers (POP3/IMAP). Encrypted.

| IRC Groupchat

Communicate securely with your Friends in a Group. Like in an IRC channel you can talk with a group of friends in a common group chat room.
You chat with symmetric encryption in these group chat rooms.

| P2P Websearch

GoldBug offers a RSS-/ATOM-Newsreader and a p2p search for these Web-URLs. It is one of a few decentral p2p search engines. GoldBug and its integrated architecture is the only p2p search engine which encrypts the URL-Search and the URL-Database.
Every user can contribute to an own community search index.
Your web search remains private.

| StarBeam FileSharing

GoldBug provides also FileSharing to Friends: Individual packets of data are encrypted, authenticated and then seeded ... based on the developed cryptographic Magnet-URI Standard.

Your Instant Definition in Decentralized Crypto.

Multi-Encrypted Messaging. Plaintext was yesterday: with GoldBug you create encrypted connections and postings to your friends. GoldBug is a decentralized social network: with encrypted chat, e-mail-client and also secure file transfers and Web-URL-Search within a RSS-Reader.
This means there is no need for commercial chat servers or advertisement related services to reach your friends and family.
This E-Mail-Client & Chat Messenger is entirely open-source and free: no costs, no ads and no service agreements about any usage of your private data.
GB is a pure spare-time community project and not financed by any third or commercial party.

Secure and open source communications suite • based on the research project Spot-on since 2010.

« Why should we encrypt? »

Secure your writings and data transfers over the internet as you would protect your loved ones:
Consider Privacy & Human Rights
as a standard - with modern cryptographic functions based on of open source libraries: RSA, ElGamal, McEliece, NTRU, AES, DSA, libgcrypt and OpenSSL.

GoldBug uses a purely native encryption with in the Network-Protocol called "Echo": Next to public keys it includes by default asymmetric end-to-end encryption. Once you have shared your keys, you are ready for Chats, E-Mails, e*IRC, Groupchat, Websearch and Filesharing.

GoldBug Messenger uses Multi-(Hybrid)-Encryption: Encrypt your Chats & E-Mails and sent it through encrypted decentral HTTPS-channels:

RSA-SSL (AES (NTRU (Message))).

GoldBug is very easy to use: Just swap once a key with your friends - and done.
It provides support for the most common transport protocols, including SCTP, TCP, UDP and Bluetooth.
And it has cool smileys ;) and secure file sharing.
Try it out with one of your friends and/or join here.

Details on Security Features

Zero-Plaintext for secure communication-transports:

Open Source: BSD License.
Only a few Crypto messengers can be operated via your own infrastructure & decenralized chat servers.
Quantum Computing Secure: GoldBug is the first messenger to implement NTRU and McEliece as an alternative to the RSA algorithm.
GoldBug allows each user to specify individual and manually set (or communicated) passwords for end-to-end encryption.
"Cryptographic Calling": "Instant Forward Perfect Secrecy" (many new, ephemeral (temporary) keys per session), which are additionally authenticated with SMP.
