Frequently Asked Questions
How does end-to-end encrypted paste work?
Type or paste your sensitive text, code, or passwords. Your browser encrypts the content using AES-256-GCM before transmission. The decryption key is contained only in the URL hash, which is never sent to any server.
Can your servers read the contents of my encrypted paste?
Never. The encryption key resides exclusively after the `#` hash fragment in the URL. Browsers never transmit hash fragments to web servers, making it mathematically impossible for us to decrypt your text.
Can I create self-destructing pastes (burn after reading)?
Yes. You can configure a paste to self-destruct immediately after it is opened once, or set a time-based expiration (5 minutes, 1 hour, 24 hours, 7 days).
Can I protect a paste with an additional password?
Yes. You can add an optional secondary password that derives a PBKDF2 encryption key for double-layer cryptographic protection.
What encryption standards are used?
We use military-grade AES-256-GCM authenticated encryption powered by the native browser Web Cryptography API (SubtleCrypto).
Does the paste tool support code syntax highlighting?
Yes. Syntax highlighting is automatically applied for JavaScript, TypeScript, Python, HTML, CSS, JSON, SQL, Rust, Go, and 20+ other languages.
Can I share confidential API keys and credentials safely?
Yes. Because of client-side encryption and burn-after-reading destruction, it is ideal for sharing API tokens, SSH keys, passwords, and server secrets.
What happens when an expired paste is visited?
Once a paste expires or reaches its view limit, the encrypted payload is permanently deleted and cannot be recovered by anyone.
Is my IP address or identity logged when creating a paste?
No. We do not log IP addresses, user agents, or personal identifiers.
Can I format the text with Markdown?
Yes. You can switch between raw code view, plain text, and rendered Markdown view.
Does the paste tool work on mobile browsers?
Yes. You can view, decrypt, and create encrypted pastes on any modern mobile smartphone or tablet.
Can I duplicate or clone an existing paste?
Yes. You can clone the decrypted text into a new paste session with a fresh encryption key.
What is the maximum character limit for an encrypted paste?
You can securely paste text documents, logs, and code files up to several megabytes in length.
Is this secure paste service completely free?
Yes, 100% free with no account creation, advertisements, or subscription fees.
How does this compare to standard pastebins like Pastebin.com?
Standard pastebins store plaintext on public databases accessible to search engines and admins. Our zero-knowledge encryption ensures only people with your private link can ever decrypt the text.
