Post-quantum security.
Total privacy. Unrivaled.
Abhigram is the world's premier modern instant messenger protected by NIST post-quantum lattice cryptography and zero-metadata ephemeral routing. Because future quantum computers must never read your conversations.
Architected for the post-quantum era.
Adversaries today are harvesting encrypted data to decrypt it once quantum computers arrive. Abhigram neutralizes this threat at the mathematical foundation.
Lattice-Based Key Encapsulation (Kyber-1024)
Every chat session establishes shared secrets using high-dimensional Module Learning With Errors (M-LWE). Even universal quantum computers running Shor's algorithm cannot reduce or factor these geometric lattice problems.
Zero Server Metadata
No phone address book uploads. No message transmission timestamps. No social relationship graphs. Servers act purely as blind, stateless packet forwarders.
ML-DSA Dilithium-5 Signatures
Cryptographic identity proofs certified with quantum-safe digital signatures, eliminating man-in-the-middle impersonation attacks permanently.
Hardware-Backed Enclave Ephemeral Storage
Cryptographic seeds are bound directly into the Android ARM TrustZone and iOS Secure Enclave. Even if a host operating system is compromised, decrypted key material cannot be extracted from hardware.
How Abhigram compares.
Legacy messengers rely on RSA and Elliptic Curve Diffie-Hellman (ECDH) which can be cracked by future quantum algorithms. Abhigram is quantum-hardened from day one.
