Mesyx - Secure message exchange

Mesyx Logo

What is Mesyx?

Mesyx is a Message and Data Exchange, it allows one to send, receive and relay messages to other parties.

It accepts standard cleartext or PGP-encrypted emails over SMTP and can relay these again to other SMTP servers. Or, the party trick: it can store these encrypted as Mesyx blobs. This thus allows interaction with the standard email system worldwide, while slowly upgrading to Mesyx everywhere.

Access to the stored data happens using Mesyx client, which can expose itself as a IMAP server, thus allowing any standard email client access.

Plainly said: Mesyx is secured messaging done properly.

Availability and Timeline

Mesyx is currently being tested by several groups in the operational security community. We are finalizing the protocols and ensuring scalability and will be offering full public service per October 2018.

The goal is the following timeline:

  • Currently: Beta-testing with several groups (SMTP Inbound/Outbound, PGP Decrypt+Remail, Mesyx storage and exchange)
  • August 2018: Invites for public testing
  • September 2018: Open Sourcing Mesyx
  • October 2018: Native iOS Mesyx client, will be made available in the Apple app store

In the mean time do not hesitate to contact us at info@mesyx.net for signup to the beta queue or to discuss your requirements.
