NEW DELHI: Zoho-backed homegrown messaging platform Arattai is poised for a big update with end-to-end encryption scheduled to be rolled out on Tuesday night, founder Sridhar Vembu said in a social media post.
Vembu said many more “cool features” on Arattai are in the works once “this big transition” is through.
“Please update the Arattai app from the Play Store/App Store and please encourage your contacts to do so. The end-to-end encryption will be enabled Tuesday night IST,” Vembu said on X.
He explained that users will be able to only exchange end-toend encrypted messages if both they and their contacts are using the latest version of Arattai.
“If you are on the latest Arattai version and your contact is on the latest version, you will only be able to use end-to-end encrypted chat with that contact,” he said. In such cases (where both sides are on the latest version), a new end-to-end chat session will be created for that contact, and the old non-end-to-end encrypted chat session will be archived.
“So you cannot continue the old chat session with any contact who is in the end-to-end encrypted version of the app. The old chat screen will simply redirect you to the end-to-end chat screen,” he elaborated.
For contacts who are in an old Arattai version, a user will be able to continue to use the old chat session only for three days. In three days, Arattai will upgrade everyone to the latest app, and at that point, end-to-end encryption will become a system-wide mandate.
In effect, these three days are a transition phase.
