Ockam is a suite of open source tools, programming libraries, and managed cloud services to orchestrate end-to-end encryption, mutual authentication, key management, credential management, and authorization policy enforcement – at massive scale.

Manage cryptographic keys, sigchains and user identities.
Search for keys, verify and import them.
Securely store passwords and secrets.
Encrypt, decrypt, sign, verify
Create a secure connection (Wormhole) between 2 computers.

A simple, modern and secure encryption tool with small explicit keys, no config options, and UNIX-style composability.

CryptPad is the Zero Knowledge realtime collaborative editor.

Encryption carried out in your web browser protects the data from the server, the cloud and the NSA. It relies on the ChainPad realtime engine.

Safely store secrets in a VCS repo (i.e. Git, Mercurial, Subversion or Perforce).

This package provides a library and a command-line tool named wormhole, which makes it possible to get arbitrary-sized files and directories (or short pieces of text) from one computer to another. The two endpoints are identified by using identical "wormhole codes": in general, the sending machine generates and displays the code, which must then be typed into the receiving machine.

Scuttlebot is an open source peer-to-peer log store used as a database, identity provider, and messaging system. It has:

Global replication
File-synchronization
End-to-end encryption

Tutanota is an open-source end-to-end encrypted email software and freemium hosted secure email service based on this software

ZeroDB enables clients to run queries over encrypted databases without exposing decrypted data to the server and without a proxy gateway.
