Traditional pastebins like Pastebin.com store your text in plaintext on their servers. Anyone with the URL can read it, and the content persists indefinitely. For sharing sensitive data — API keys, configuration files, credentials, or private code — you need an encrypted alternative.
Why you need an encrypted pastebin
Standard pastebins were designed for sharing code snippets publicly. They offer no encryption, no expiration, and no access control. This makes them dangerous for anything confidential. An encrypted pastebin encrypts your content before it leaves your browser, ensuring the server never sees the plaintext.
Best encrypted paste services in 2026
1. PassLink
PassLink encrypts text in your browser using AES-128-GCM and generates a one-time link that self-destructs after viewing. It supports password protection, configurable view limits, and expiration timers. No account required.
Best for: Quick, secure sharing of credentials and secrets with non-technical recipients.
2. PrivateBin
PrivateBin is an open-source, self-hosted pastebin with client-side AES-256-GCM encryption. It supports syntax highlighting, discussions, and configurable expiration. Requires self-hosting.
Best for: Organizations that need full control over their data and infrastructure.
3. 0bin
0bin is a minimalist encrypted pastebin that uses client-side encryption. It is lightweight and easy to self-host, with a simple interface focused on pasting and sharing.
Best for: Developers who want a minimal, no-frills encrypted paste tool.
4. Ghostbin (archived)
Ghostbin was a popular encrypted pastebin that has since been archived. It supported syntax highlighting and expiration but is no longer actively maintained.
Note: No longer available. Consider PassLink or PrivateBin as alternatives.
5. Hastebin / Toptal Haste
Hastebin is an open-source pastebin focused on developer experience with keyboard shortcuts and clean UI. However, it does not offer client-side encryption by default.
Best for: Public code sharing where encryption is not required.
