Deleto

DELE.TO is a secure secret-sharing tool for sending passwords, API keys, and other sensitive text without exposing the plaintext to the service. It encrypts secrets directly in the browser before they are sent, then creates a link that can automatically expire after a defined period or number of views.

It is designed for people who need to share sensitive information quickly without putting plaintext secrets into chat, email, or other everyday communication channels. Basic sharing requires no signup, while the zero-knowledge architecture keeps encryption keys in the URL fragment rather than on the server.

Key Features

Client-Side Encryption

Encrypt sensitive information directly in the browser before it leaves your device.

• AES-256-GCM encryption
• Encryption happens in the browser
• Plaintext secrets are not exposed to the service
• Encryption keys remain in the URL fragment

Self-Destructing Links

Create links that automatically stop working after a defined condition is reached.

• Time-based expiration
• View-based expiration
• Secrets disappear after being read
• Useful for temporary credential sharing

No Signup Required

Share sensitive information without creating an account for basic use.

• No account required
• Designed for quick one-off sharing
• Simple link-based workflow

Privacy-Focused Design

DELE.TO states that it does not retain shared secret data or track users through IP logging.

• No IP logging
• No user tracking
• Zero-knowledge architecture
• Sensitive content is encrypted before being transmitted

Open Source

The project's source code is publicly available for inspection.

• Open-source implementation
• Available for security review
• Code available on GitHub
• Transparent encryption workflow

Command-Line Interface

Use DELE.TO directly from terminal workflows when handling sensitive output.

The CLI can work with:

• Piped command output
• Files
• Environment variables
• .env files
• Kubernetes output
• Other shell-based workflows

Browser Extension

Create secure, time-limited sharing links directly from selected text in your browser.

• Select sensitive text
• Create an encrypted link
• Set an expiration
• Share without leaving the current webpage

Built For Secure Secret Sharing

DELE.TO is designed for people who need to transfer sensitive information temporarily without placing plaintext credentials into normal messaging channels.

It is particularly suited to:

• Developers sharing API keys and credentials
• DevOps teams handling deployment secrets
• Security-conscious users sharing sensitive text
• IT teams transferring temporary credentials
• Technical teams working with shell and Kubernetes workflows

Common Use Cases

Sharing Passwords

Send a password through an expiring link instead of putting the plaintext credential directly into an email or chat message.

Sharing API Keys

Create a temporary link for transferring API keys while limiting how long the secret remains accessible.

DevOps Workflows

Use the CLI to encrypt sensitive terminal output, environment variables, .env files, or Kubernetes-related information.

Quick Credential Handoffs

Share sensitive information with a colleague without requiring either person to create an account.

Browser-Based Sharing

Use the browser extension to turn selected text into a temporary encrypted link directly from a webpage.

Zero-Knowledge Secret Sharing

DELE.TO's encryption model is built around keeping the plaintext secret away from the server.

The browser encrypts the data before transmission, while the encryption key is kept in the URL fragment. This means the service can handle the encrypted payload without needing access to the unencrypted secret.

Expiring Secret Links

Instead of sending a permanent message containing sensitive information, DELE.TO creates a temporary link that can be configured around time or view limits.

That makes the link suitable for situations where a credential only needs to be accessible briefly or should disappear after it has been retrieved.

CLI & Developer Workflows

The command-line interface makes DELE.TO useful beyond browser-based sharing. Developers can integrate secret sharing into existing shell workflows and encrypt information coming from commands, files, environment variables, or infrastructure tools.

This makes the tool particularly relevant when sensitive information already exists in a terminal-based workflow.

Cloud Option For Teams

DELE.TO also offers a dedicated cloud option for teams that want an isolated deployment.

The team-focused option provides:

• Dedicated deployment
• Custom domain
• Managed hosting
• An isolated environment for organizational use

Why It Matters

Sending passwords, API keys, and other secrets through ordinary communication tools can leave sensitive information sitting in message histories or email threads. DELE.TO provides a temporary link-based workflow where the secret is encrypted before it reaches the service.

The combination of client-side encryption, expiring links, no-signup sharing, open-source code, CLI support, and browser integration makes it useful for temporary sharing of sensitive information without exposing plaintext secrets to the service.

Share Sensitive Information With DELE.TO

Encrypt passwords, API keys, and other sensitive text in your browser, create an expiring link, and share it without putting the plaintext secret into chat or email.
