About

ShieldFive is end-to-end encrypted cloud storage. Every file and its name is encrypted in your browser before upload (post-quantum ML-KEM-1024 with XChaCha20-Poly1305 by default on the web), so ShieldFive stores only ciphertext and never holds your keys. Plans: 10 GB free with no card, monthly or yearly subscriptions, or the Lifetime Vault: 2 TB for EUR 199 paid once until 31 Oct 2026, then EUR 249, no renewals, with a 30-day refund. You can preview PDFs, images, spreadsheets and Word documents in the browser, share files with an expiry date and password, and revoke links at any time. Firms can also collect documents from clients through a request link with a PIN and checklist; clients need no account (EUR 29 per seat per month). Current limits: web app today, Android app in testing, no desktop sync client or iOS app yet. The encryption core is open source (Apache-2.0); no external security audit has been completed yet.

About

Solarium is a fully decentralised, end-to-end encrypted, censorship-resistant instant messenger based on the Solana blockchain. Solarium is currently in alpha phase, running on the Solana devnet. All messages in Solarium are end-to-end encrypted using the XChaCha20-Poly1305 symmetric encryption algorithm, using a 256-bit content encryption key (CEK) that is shared for all messages in a given channel. The message content in Solarium is not directly signed, i.e. the data itself, once decrypted, does not contain details about the sender. Instead, the blockchain transaction that adds the message to the channel is signed by the sender.
