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.

« 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.

    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.
