SimpleX
SimpleX Chat
The first messenger without user IDs. Other apps have user IDs: Signal, Matrix, Session, Briar, Jami, Cwtch, etc. SimpleX does not, not even random numbers. This radically improves your privacy. Many users asked: if SimpleX has no user identifiers, how can it know where to deliver messages? To deliver mesages, instead of user IDs used by all other platforms, SimpleX uses temporary anonymous pairwise identifiers of message queues, separate for each of your connections — there are no long term identifiers. You define which server(s) to use to receive the messages, your contacts — the servers you use to send the messages to them. Every conversation is likely to use two different servers. This design prevents leaking any users' metadata on the application level. To further improve privacy and protect your IP address you can connect to messaging servers via Tor. Only client devices store user profiles, contacts and groups; the messages are sent with 2-layer e2e encryption.Starting Price: Free -

Sendmail
Proofpoint
The sendmail Sentrion platform is specifically designed for large, complex environments, but we make a subset of that solution available as an open-source offering. Sentrion is not for everyone, but if you are using open source email for a large complex environment and need an enterprise platform that will enable your messaging roadmap for years to come (virtualization, consolidation, cloud migration, etc.). The Domain Keys Identified Mail (DKIM) Internet standard enables email senders to digitally sign their messages so that receivers can verify that those messages have not been forged. The DKIM sender authentication scheme allows the recipient of a message to confirm a message originated with the sender’s domain and that the message content has not been altered. A cryptography-based solution, DKIM provides businesses an industry-standard method for mitigating email fraud and protecting an organization’s brand and reputation at a relatively low implementation cost. -

Wormhole
Wormhole
Simple, private file sharing. Wormhole lets you share files with end-to-end encryption and a link that automatically expires. So you can keep what you share private and make sure your stuff doesn't stay online forever. End-to-end encryption prevents your data from falling into the wrong hands. With end-to-end encryption, data is encrypted and decrypted only at the "end points". That means that service providers in the middle don't have access to the keys, and therefore can't read your data. We built Wormhole with end-to-end encryption. Wormhole lets you share files more quickly and easily than any other file sending service. And we do it without sacrificing your privacy. When you use Wormhole, a key is generated on your device and used to encrypt your files. In transit, your data is unreadable to Wormhole and service providers like your ISP. The key never leaves your device and you're the only one who has it – unless you decide to share it. -

cryptography
cryptography
cryptography includes both high-level recipes and low-level interfaces to common cryptographic algorithms such as symmetric ciphers, message digests, and key derivation functions. Encrypt with cryptography’s high-level symmetric encryption recipe. cryptography is broadly divided into two levels. One with safe cryptographic recipes that require little to no configuration choices. These are safe and easy to use and don’t require developers to make many decisions. The other level is low-level cryptographic primitives. These are often dangerous and can be used incorrectly. They require making decisions and having an in-depth knowledge of the cryptographic concepts at work. Because of the potential danger in working at this level, this is referred to as the “hazardous materials” or “hazmat” layer. These live in the cryptography.hazmat package, and their documentation will always contain an admonition at the top.Starting Price: Free -
