What is Hansel by Seedling?

Editorial review
Hansel by Seedling is a sovereign communication platform that combines email and encrypted messaging into a single, private system. Built in response to corporate account lockouts, it ensures that users own their email server, encryption keys, and data, the platform cannot read messages, suspend accounts, or access stored communications. The product features the proprietary Wicked Crumbs Protocol, which provides rotating identities, tamper-evident message chains, and cryptographic spam prevention. Hansel is designed for teams and individuals who want full control over their communications without relying on third-party providers like Google or Microsoft.

Hansel by Seedling FAQ

How does the Wicked Crumbs Protocol prevent spam differently than traditional filters?

The Wicked Crumbs Protocol solves spam architecturally: without your cryptographic key, no sender can deliver a message to your inbox. There are no filters, AI scanning, or keyword blocks — the protocol mathematically prevents unsolicited mail from reaching you.

Can Hansel be used with existing custom domains?

Yes. Hansel supports sending and receiving email from your own domain (e.g., yourname@yourdomain.com). You need to set up your own mail server, signing keys, and DNS records. Recipients receive a normal email and do not need any special app.

What happens if I lose my device or encryption keys?

Since keys stay on your device and are never stored on Hansel's servers, losing your device without a backup means you lose access to your encrypted messages. The platform cannot recover your keys by design. Users are encouraged to back up their keys securely.

Is there a way to use Hansel without self-hosting a mail server?

Hansel is built around the principle of owning your infrastructure. A Hansel account is free to create, but the product assumes you will run your own email server. There is no cloud-hosted option that stores your keys or data on a third-party server.

How does the alias system work across different organizations?

Each alias functions as a separate email address with its own inbox, sent folder, and identity. You can create aliases for work, personal, or project communications, and each alias maintains independent message storage and settings — all under one account.

Does Hansel support team messaging and enterprise admin features?

Yes. Hansel includes encrypted team messaging and an enterprise admin console with features like DLP (Data Loss Prevention) and eDiscovery built in. You can manage multiple users, set profile PIN locks, and use a device admin code for IT administration.

How does Hansel ensure that messages are not forged or replayed?

The Wicked Crumbs Protocol uses a tamper-evident message chain: each message carries a cryptographic proof linked to the previous message in the chain. This prevents forgery and replay attacks because the chain cannot be altered without detection.

What platforms are currently supported for the Hansel client?

The Hansel desktop client is currently available for Windows 10 or later. macOS, iOS, and Android clients are listed as 'coming soon.' An internet connection is required for email and messaging sync.
