Nostr signing without private-key sprawl

Diogel protects Nostr keys, secures signing authority, and lets people, apps, teams, and agents sign safely without taking custody of the private key.

Protect your keys

Private keys should not be casually exported to every client. Diogel keeps signing material inside controlled boundaries and returns signatures instead of raw keys.
  • Browser protection
    Porwr keeps your private keys inside the browser extension. Web apps get signatures, not your key.
  • Mobile protection
    Android keeps keys isolated on your phone. Signing requests are reviewed before approval.
  • Team protection
    Bancwr puts governance around shared signing. Team members never see the private key.

Signing is a controlled operation

Signing should be a deliberate act, not an invisible side effect. Requests are reviewed, permissioned, scoped, and logged where useful.
  • Per-site permissions
    Approve or reject signing requests per domain and per event kind. Granular control over what gets signed.
  • Explicit approval flows
    Every signing request is visible. No invisible side effects, no auto-signing without consent.
  • Audit trails
    Bancwr provides compliance-oriented audit logs so organisations know exactly what was signed and by whom.

Standards-compatible

Diogel fits the Nostr ecosystem — NIP-07 browser signing, NIP-55 mobile signer flows, and Nostr bunker patterns for remote and team-controlled signing.
  • NIP-07 browser signing
    Porwr implements the standard window.nostr interface. Works with any Nostr web app.
  • NIP-55 mobile signing
    Android supports modern signer flows for app-to-signer requests on mobile.
  • Nostr bunker / remote signing
    Bancwr aligns with the Nostr bunker pattern for server-side and team-controlled signing.

One suite, three products

The Diogel suite solves the same problem at three levels — personal browser signing, mobile signing, and organisational key custody.
Porwr
Secure Nostr signing for the browser. Web apps get signatures, not your private key.
Android
Dedicated mobile Nostr signing for Android. Approve app requests while keeping keys on-device.
Bancwr
Self-hosted Nostr signing for teams. Shared brand authority without shared private-key chaos.
