Secret sharing tools compared: what to look for

Several tools let you share a secret once and then delete it. They differ in where encryption happens, whether you can host them yourself, and which extra features they offer. This page explains the differences so you can choose the right one. Check each vendor's own documentation for current details, as products change.

The main difference: where encryption happens

Some tools encrypt the secret in your browser, so the server only ever stores ciphertext it cannot read. Others, including SecureVoult, encrypt the secret on the server before storing it. Browser-side encryption gives a stronger guarantee against a compromised server; server-side encryption makes features such as passphrase checks, expiry handling and secret requests simpler to offer.

SecureVoult sends secrets over HTTPS and stores them AES-256 encrypted, decrypting only when the link is opened. We say this plainly because you should know how any tool you choose treats your data.

Questions to ask about any tool

  • Does encryption happen in the browser or on the server?
  • Can you self-host it, or is it a hosted service only?
  • Can you set view limits and expiry, and add a passphrase?
  • Are there file attachments, secret requests or team features?
  • What does it cost, and is there a free tier without an account?

Where SecureVoult fits

  • Create one-time links without an account, with view limits, expiry and optional passphrase.
  • Secret requests, so someone can send you a credential without email.
  • File attachments and private chat rooms on paid plans.
  • A hosted service, with a free plan and paid plans for higher limits.

Detailed comparisons

Choosing

If you need to run the tool on your own infrastructure, look at open-source options. If you want a hosted tool with request links, attachments and a dashboard, a hosted service fits better. Whatever you choose, pick short expiries and send passphrases over a separate channel.
