Share Secrets Safely.
Burn Upon Reading.
Client-side AES-256-GCM encryption. The decryption key lives in the URL hash fragment and never touches any server. Permanently destroyed upon first view.
Zero-Knowledge Architecture
Client-side AES-256-GCM encryption with 256-bit keys stored strictly in the URL hash fragment (#key=...). Even database administrator cannot inspect secret content.
Enterprise Governance & SSO
Active Directory (LDAPS) & Microsoft Entra ID integration, 7 granular RBAC system roles, and immutable SHA-256 tamper-evident audit logs for SOC 2 and ISO 27001 compliance.
Automated 1-Command Deploy
Deploy your private enterprise instance in under 5 minutes on Ubuntu with Docker, Nginx reverse proxy, and Let's Encrypt SSL via curl -fsSL https://get.gosecureshare.io/install.sh | bash.
How GoSecureShare Protects Your Confidential Data
True client-side zero-knowledge encryption ensures your secret never traverses the network in plaintext.
lock In-Browser Encryption
When you create a secret, your browser's native Web Crypto API (window.crypto.subtle) encrypts the payload using AES-256-GCM with a cryptographically secure 256-bit symmetric key.
link URL Hash Fragment Key
The decryption key is appended after the URL hash fragment (#key=...). According to HTTP standard RFC 3986, hash fragments are strictly client-side and are never sent to the server or logged in access logs.
local_fire_department Burn-After-Reading
The recipient's browser retrieves the ciphertext and decrypts it locally. In the same database transaction, the server atomically destroys the record. The secret is permanently unrecoverable.
The Problem with Sharing Passwords via Slack, Teams & Email
Every unencrypted credential shared in work chats becomes a permanent liability.
cancel Everyday Channels Leak Passwords
- Indefinite Chat History: Slack, Teams, and email archive messages indefinitely across corporate backups.
- Search Indexing: Sensitive database passwords and API tokens appear in internal workplace search results.
- Third-Party Integrations: Bots and chat integrations with read permissions can harvest credentials.
- Offboarding Blind Spots: Ex-contractors and former employees retain chat histories on personal devices.
check_circle The GoSecureShare Zero-Footprint Solution
- Ephemeral Links: Share a 1-time self-destructing link instead of pasting plain text into chat channels.
- Zero Server Footprint: Encrypted with AES-256-GCM. Deleted from the server the second it is decrypted.
- Passphrase Shield: Send the passphrase via another channel (SMS or voice) for instant two-factor defense.
- Forensic Certainty: Senders know with absolute certainty if and when a credential link was opened.
Engineered for Security-Conscious Teams
Comprehensive features designed for developers, sysadmins, IT support, and enterprise SecOps.
Burn-After-Reading
Instantly and irreversibly deletes the secret from backend storage upon first viewing. Once read, it can never be decrypted again.
Passphrase Defense
Adds client-side PBKDF2 key derivation. The recipient must enter the shared passphrase to derive the AES decryption key.
Custom Expiration TTL
Configure precise retention lifetimes from 5 minutes to 7 days on the web version, and up to 90 days on enterprise deployments.
Mobile QR Decryption
Generate instant high-resolution QR codes to securely transfer passwords from desktop directly to mobile devices without typing.
100% Self-Hostable
Run GoSecureShare completely on-premise on your own servers or VPC with Docker Compose. Zero telemetry and full data residency.
Compliance Ready
Meets strict requirements for SOC 2 Type II, ISO 27001, HIPAA, and GDPR by ensuring credentials are never stored in unencrypted form.

Frequently Asked Questions
Everything you need to know about one-time secret links and zero-knowledge encryption.
What is a one-time secret and how does it work? expand_more
A one-time secret is an ephemeral, self-destructing message encrypted in your browser using AES-256-GCM. The decryption key is contained strictly within the URL hash fragment (#key=...). Once the recipient opens the link and decrypts the secret, the server permanently purges the ciphertext from storage, making it impossible to read again.
Can GoSecureShare or server administrators read my secret? expand_more
No. GoSecureShare uses client-side zero-knowledge architecture. Encryption occurs in your web browser before data leaves your machine. The decryption key is placed after the hash (#) in the URL, which browsers never send to web servers (RFC 3986). The server only stores unreadable ciphertext and has zero ability to decrypt your payload.
Why is sharing passwords via Slack, Microsoft Teams, or email unsafe? expand_more
Email, Slack, and Microsoft Teams store plain-text conversation histories indefinitely across cloud backups, search indexes, third-party apps, and compliance archives. If an account, device, or third-party backup is compromised, all historical credentials become exposed. GoSecureShare eliminates this risk by ensuring credentials exist only until read, leaving zero permanent footprints.
How does GoSecureShare compare to Privnote and Password Pusher? expand_more
Unlike traditional services that encrypt on the server or run intrusive advertising and analytics scripts, GoSecureShare uses pure client-side AES-256-GCM encryption with zero advertising, zero trackers, and full open-source auditability. GoSecureShare also offers optional passphrase defense and full on-premise self-hosting.
What happens to my secret after the link is opened? expand_more
The moment a secret is opened, the backend atomically deletes the encrypted database entry. Subsequent visits to the same link will receive a 'Secret Burned or Expired' notice. If a secret is never opened, it is automatically purged when its expiration timer expires.
How does the optional passphrase protection work? expand_more
When you enable a passphrase, the browser derives an additional cryptographic key using PBKDF2 with SHA-256. The recipient must enter this exact passphrase in their browser to unlock and decrypt the payload, providing out-of-band two-factor protection.
Is GoSecureShare free to use? expand_more
Yes! GoSecureShare is 100% free to use for individuals and teams with no account registration or payment required. For organizations needing on-premise installation, SSO (LDAP/Entra ID), RBAC, and SOC 2 audit logs, a self-hosted Enterprise Edition is available.
Can I deploy GoSecureShare on my own private servers? expand_more
Yes. GoSecureShare Enterprise can be deployed on any Linux server, private cloud (AWS, GCP, Azure), or on-premise Docker environment using an automated 1-command installer with full data residency compliance.
