Free, open source, and fully client-side. Nothing is ever uploaded. Try it live → · VERNAM.app → ⭐️ We just launched, and a single star genuinely helps. VERNAM is free and open source, with nothing to sell and no one funding it. If you think strong encryption should be free for everyone, please star us on GitHub . It helps more people find the project and keeps it alive. --- VERNAM is a tiny, drag-and-drop file encryptor that runs entirely in the browser. Drop a file, set a passphrase, done. Drop the encrypted file back in, type the passphrase, get your original. That is the whole product. It is named after Gilbert Vernam , inventor of the one-time pad, the only cipher ever mathematically proven unbreakable. VERNAM (the tool) is not a literal one-time pad, but it is built on its descendant: XChaCha20, a modern stream cipher. Made by PrivacyTools.io. Why it is different - Nothing leaves your device. No uploads, no cloud, no servers. Go offline and it still works. - No account, ever. No sign-up, no email, no tracking. - Any file, any size. Large files stream straight to disk instead of eating your memory. - Tamper-evident. Change one byte and decryption fails loudly. - Open source. Audit it, fork it, host it yourself. Cryptography - Key derivation: Argon2id stretches your passphrase into a 256-bit key. - Encryption: XChaCha20-Poly1305 via libsodium's secretstream (authenticated, streaming). - Integrity: per-chunk authentication plus trun","default_branch":null,"files":null,"tree":[],"storefront":"/r/LifetimeLabsDev","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/LifetimeLabsDev/VERNAM/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
