## What it is
PrivateBin is a minimalist, self-hosted pastebin where the server stores only encrypted data and never learns the paste contents. Encryption and decryption happen in the browser using 256-bit AES-GCM, with optional passwords, expiring pastes, and self-destruction.

## Use cases
- share sensitive text or code snippets securely
- self-host a zero-knowledge pastebin
- send self-destructing one-time messages
- share a paste with a password
- avoid storing plaintext user content on my server
- share confidential notes via a link

## When to choose
- you want the server to have zero knowledge of pasted content
- you need self-hosted pastes with expiration or one-time viewing
- you want plausible deniability for hosted content

## When to avoid
- you need to search or index pastes server-side
- you cannot serve the instance over HTTPS
- you need large file hosting rather than text pastes
