Secure messaging · Cryptography

Conversations that stay private.

SAKTI Chat protects organisational and personal conversations with forward secrecy: every session uses fresh keys, so a stolen key cannot unlock past messages.

The problem

One leaked key should not expose years of conversations.

Many messaging tools rely on long-term keys. If a key is stolen, an attacker may be able to decrypt past messages. Forward secrecy closes that gap.

Connect

Users establish a session with a secure key exchange.

Encrypt

Messages are encrypted with short-lived session keys.

Rotate

Keys are discarded and replaced, never reused.

Protect

Past messages stay safe even if a device is later compromised.

FAQ

Questions we hear often.

What is forward secrecy?

Each session uses temporary keys, so stealing one key later cannot unlock earlier messages.

Can we deploy it internally?

Yes. SAKTI Chat is designed for organisational use.

Is this a finished commercial product?

It is a research-based student startup moving from validated prototype toward pilots with real users.

Can we partner or run a pilot?

Yes. We are looking for organisations willing to test the solution in real conditions and share feedback.
