    Hey HN, I’m Ilias, 19, from Paris. I built Ellipticc Drive, an open-source cloud drive with true end-to-end encryption and post-quantum security, designed to be Dropbox-like in UX but with zero access to your data, even by the host. What’s unique: Free 10GB for every user, forever. Open-source frontend (audit or self-host if you want) Tech stack: Frontend: Next.js Crypto: WebCrypto (hashing) + Noble (core primitives) Encryption: XChaCha20-Poly1305 (file chunks) Key wrapping: Kyber (ML-KEM768) Signing: Ed25519 + Dilithium2 (ML-DSA65) Key derivation: Argon2id → Master Key → encrypts all…

    Hi HN, we are the developers from Tuta (formerly Tutanota), the German end-to-end encrypted email provider, and we recently released the world's first post-quantum encryption for email. We have included a full technical write-up of the cryptography involved in these changes and we have released it for open public review. This document specifies TutaCrypt, a protocol designed for hybrid email encryption in Tuta Mail. The protocol combines a classical Elliptic-Curve-Diffie-Hellman key exchange with a post-quantum KEM. The goal is to replace the usage of RSA in Tuta Mail. In the remainder of…

    Hi everyone! We started working on this project last year because a password manager that we used was being sold to another company and stopped offering their service. We were not happy with the alternatives that were available so we decided to give it a shot and build our own. We are now at a point where we have a working Beta and are looking for some feedback from the community. The main idea is to have data synchronization without a central server (single point of failure). When you create a Vault (inside which you can store your credentials and other sensitive data), you can "Link" it to…

    Hi! I got tired of setting up tools I can't explain to a team in a few words like sops or git-crypt, just to store few files with environment variables or secrets, so I built lockenv as a simple alternative. It's basically a password-protected vault file you commit to git. No gpg keys, no cloud, just lockenv init, set a password, and lock/unlock the secrets. This tool integrates with OS keyring, so you're not typing passwords constantly. Should work on Mac/Linux/Windows, but I tested it only on linux so far. I am not trying to replace any mature / robust solution, just…

    Keeper is an embeddable secret store (Argon2id, XChaCha20-Poly1305 by default). Four security levels, audit chains, crash-safe rotation. Vault is overkill for most use cases. This is for when you ge paranoid about env and need encrypted local storage that doesn't suck. No security through obscurity, hence, It's still early, so now's the best time to find weird edge cases, race conditions, memory leaks, crypto misuse, anything that breaks. The README has a full security model breakdown if you want to get adversarial.

    Hello HN! We are developers and security researchers making tools for developers to encrypt data at an application level while maintaining sole control of their keys. We believe that data should always be encrypted unless it is part of an active computation. Encryption is relatively easy, but key management is challenging. There are plenty of encryption tools and SDKs that are out there (Hashicorp Vault, AWS KMS etc.) but we are focusing on ease and speed of implementation, developer experience and self custody of keys. A few months ago, we quit our jobs and started full time on Phase. So…
