Zero-Knowledge Encrypted Paste
Your data is encrypted in your browser before it ever reaches our servers. We can never read your pastes.
How It Works
1. You Write
Enter your text, code, or attach files. Choose expiration and security options.
2. Browser Encrypts
AES-256-GCM encryption happens entirely in your browser. The key never leaves your device.
3. Share the Link
The decryption key is in the URL hash (#) — it's never sent to the server. Only the link holder can decrypt.
Random Password Generator
Generate cryptographically secure passwords instantly. Powered by the Web Crypto API.
Why SecureBin.ai?
Military-Grade Encryption
AES-256-GCM — the same encryption standard used by governments and military worldwide. 256-bit keys with authenticated encryption.
True Zero Knowledge
The decryption key exists only in the URL fragment (#), which is never sent to our servers. We physically cannot read your data.
Self-Destructing Messages
Burn after reading — your paste is permanently deleted from our servers the moment it's viewed once. Perfect for sharing secrets.
Encrypted File Sharing
Attach PDFs, images, documents up to 50MB. Every file is encrypted client-side with the same AES-256 protection as your text.
Password Protection
Add an extra layer with PBKDF2 password-derived keys (600,000 iterations). Recipients need both the link AND the password.
Developer Friendly
Syntax highlighting for 18+ languages, Markdown rendering, code formatting, and one-click copy. Share code snippets securely.
No Registration Required
No accounts, no email, no tracking cookies. Just paste, encrypt, and share. Complete anonymity by design.
Open Source & Auditable
Every line of code is open source. Audit the encryption yourself. No backdoors, no trust required — verify everything.
Use Cases
Share Passwords
Securely share credentials with team members. Set burn-after-reading so the password is destroyed after viewing.
Share Code Snippets
Syntax-highlighted code sharing with 18+ language support. Perfect for debugging, code review, or sharing configs.
Confidential Documents
Share sensitive PDFs, contracts, and files with end-to-end encryption. Auto-expire after a set time period.
