Secure Password Vaults for Teams, Businesses, and You

SHRD is built with a zero-knowledge architecture. We don’t store passwords, recovery keys, or decrypted content; ever. All encryption and decryption happens locally on your device. There is no master password, and no vault export is ever needed to share a single item.

No. SHRD is intentionally non-recoverable. If you lose your private key, your data is permanently inaccessible by design. There are no developer backdoors, fallbacks, or server-side resets.

You can grant access to individual items through a cryptographic handshake or generate an ephemeral link with a built-in expiry. Each share is end-to-end encrypted and tracked immutably.

No. SHRD replaces passwords with persistent public/private keypairs. This eliminates phishing risk and password fatigue. You authenticate using cryptographic identity, not guessable secrets.

Nothing usable can be extracted. All data is encrypted before it ever reaches our servers. Even full disk access doesn’t help. SHRD stores opaque blobs and never handles encryption keys. The entire database can be copromised and zero risk is to you. If we as root cen't get it, they can't either.

Yes. SHRD offers a fully self-hosted version for teams that want absolute control. You own the data, the infrastructure, and the keys — we provide the system, not the access.

Absolutely! and if it were us, we’d recommend it. If you prefer not to host SHRD yourself, NMESYS can provide fully isolated instances with dedicated databases, keys, and access boundaries. While the platform runs on a shared architecture, each instance is cryptographically and logically independent. We can host thousands of these in parallel. Yours would be yours alone.

SHRD treats every file attachment, like PDFs or documents, as encrypted data from the moment it's created. Files are encrypted client-side before they ever leave your device. Our system stores only the encrypted binary data, with no ability to preview, parse, or execute files. This prevents any form of malicious payload exploitation, like the recent vulnerabilities found in open platforms.

Files can only be decrypted by users who have been explicitly granted access, and all decryption happens locally. Our approach eliminates the server as an attack vector entirely.
