Encrypt and decrypt messages directly in your browser using RSA and the Web Crypto API. No server, no database, no external libraries. Just your privacy.
A privacy-focused, client-side encrypted messaging application that enables secure message exchange via AES-256 encryption embedded directly in URL hashes. No server required, no data collected—just pure end-to-end encryption in your browser.
End-to-end encryption library for browser to secure authentication and sensitive data with zero-knowledge architecture.
Browser-based steganography suite — LSB substitution, DCT-domain hiding, and adaptive embedding with live chi-squared steganalysis. Hide the message, not just the content.
🔐 Zero-server API key sharing for AI agents. Browser-only AES-256-GCM encryption. Secure, private, fast.
Browser-based public-key basics — RSA-OAEP encryption and RSA-PSS signing side by side on one real 2048-bit pair, with a wrong key failing on purpose, a stranger's note your key still opens, and a tampered note the signature refuses
Browser-based randomness basics — two 32-byte keys that pass identical look-random checks, one from crypto.getRandomValues and one from a real ChaCha20 stream started at a four-digit PIN, and then that second key rebuilt by counting to ten thousand while every check on the page still reports success
xsukax Secure Share is a zero-knowledge file sharing application that ensures complete privacy through client-side encryption. Files are encrypted in your browser before upload, and only the intended recipient can decrypt them. The server never has access to your files or encryption keys.
Stegabyte — browser-first steganography and encryption platform. AES-256-GCM + PBKDF2 + PNG LSB + Rust-compiled WASM core.
Crypto_Master is a research-backed cryptography learning and experimentation platform. Built on modern security standards and browser-native cryptography, it enables encryption, hashing, digital signatures and legacy cipher demonstrations with transparent explanations, educational warnings and printable reports. Fully offline and privacy-first.
Browser-based CKKS approximate FHE demo — encrypted floating-point arithmetic, homomorphic neural network inference, rescaling, and the complete FHE trilogy (TFHE + BGV/BFV + CKKS). Part of the crypto-lab suite.
Browser-based bcrypt deep-dive — anatomy, cost factor benchmarking, timing-safe verification, and a real-world breach simulation. Part of the crypto-lab suite.
Browser-based Feldman VSS and Pedersen VSS demo — verifiable secret sharing with live cheating dealer detection, commitment verification, and the layer beneath FROST and threshold wallets.
Browser-based key agreement for a first-time reader — one real X25519 exchange with both sides' secrets compared byte for byte, the eavesdropper's complete transcript and a guess against the real curve that will not land, and a stranger who answers in Bob's place while every check still passes. No modulus, no exponent, no discrete log.
Browser-based zk-STARK demo — AIR constraints, FRI polynomial commitments, and end-to-end Fibonacci proof. No trusted setup. Post-quantum secure. The protocol behind StarkNet, StarkEx, and Risc Zero.
Browser-based Yao's Garbled Circuits demo — gate-by-gate garbling, oblivious transfer for input wires, and the Millionaire's Problem solved end-to-end. The foundational two-party MPC protocol.
