August 02, 2016 - New EncroChat Secure IM Client ver 6.1.9

Release Notes

New or Improved Features
  • New EncroChat Push infrastructure
    • Summary: After a year of planning, coding and testing, EncroChat secure chat messages are now pushed to the user as soon as they are received by the messaging service. The sender initiates the data transfer rather than the recipient. Our former infrastructure was based on the more standard, but inefficient, pull model where receipients would constantly request any new information be sent.
    • EncroChat has deployed numerous distributed server endpoints globally. Our push infrastructure is designed to be more resistant to network interruptions and attacks (i.e. Distributed Denial of Service - DDOS).  Subscribers will have a noticeably more stable connection worldwide.
    • These new push server endpoints contain no metadata or key information of subscribers. All metadata (i.e. contact roster) and keys for subscribers are negotiated by and contained within their own EncroChat subscriber device. Note: EncroChat subscriber devices have always directly negotiated their own keys with one another and never copied any of this information to servers. What we want to make clear here is the push servers contain zero useful data to third parties and have no single point of failure. So issues like the recent Ennetcom PGP server takedown by government authorities cannot happen to us as the servers are distributed and not a treasure trove of information. Most of our competitors still insist on keeping private keys of all their subscribers, copies of many of their encrypted messages, and large chunks of metadata like contact lists and even notes on their servers.
  • Encrypted Camera function
    • Due to popular demand of many of our subscribers, EncroChat now has picture messaging capabilities. (Note: your phone has to have an installed physical back camera). Balancing security with need for this functionality, we have succeeded with the following caveats:
      • Optional installed function by subscriber through request to their reseller to enable.
      • Cannot permanently save sent or received pictures.  All pictures have a burn time up to a maximum of nine days.
      • Cannot forward pictures.
      • Does not show a thumbnail (preview) in a chat.  Must click on it to preview for enhanced privacy.
      • A displayed picture does not disclose any details of user account while being previewed.
      • You can override burn time and delete pictures whenever you wish.
      • All pictures are temporarily stored in the encrypted EncroChat database within an encrypted partition, not as flat files in a directory.
  • Roster storage
    • Client contact roster for EncroChat must now be backed up on EncroNotes. If a subscriber device is lost, stolen, or wiped the only way to get your EncroChat contact roster back is to backup this information on EncroNotes.
  • Increased Performance and Battery life improvements
    • Fixed several issues which contributed to "keyboard lag" during conversations.
    • Fixed several issues which caused "Application not responding" in large chat conversations.
