**NOTE**: httpaste is publicly hosted at [httpaste.it](http://httpaste.it) and as a hidden Tor service ([https://paste77ubkwxy4fqezffsmthxdh3xerwi72tlsw2mch7ecjhw2xn7iyd.onion](https://paste77ubkwxy4fqezffsmthxdh3xerwi72tlsw2mch7ecjhw2xn7iyd.onion)).
Both services are to be considered evaluatory, as long as the source code
is in pre-release. Regarding voidance of pre-release status, see [Open Issues](https://victorykit.atlassian.net/issues/?jql=project%20%3D%20HTTPASTE%20AND%20fixVersion%20in%20(1.1.0-beta%2C%201.2.0-beta%2C%201.3.0)), for more information.
httpaste is a pastebin application for easily pasting and retrieving data over
HTTP from shell environments and web browsers. It is inspired by [sprunge.us](http://sprunge.us)
and [ix.io](http://ix.io/), but focuses on extendability, advanced security, with little to
no trade-off to simplicity. It can be hosted through WSGI, CGI, Fast CGI, or
as a standalone evaluation server. It offers multiple storage backends, such as
a filesystem backend, SQLite backend, MySQL backend, or MongoDB backend.
This program offers an HTTP interface for storing public and private data
(a.k.a. pastes), commonly referred to as a pastebin application. It is inspired by [sprunge.us](http://sprunge.us) and [ix.io](http://ix.io/). It can be hosted through WSGI, CGI, Fast
CGI, or as a standalone evaluation server. It offers multiple storage backends,
such as a filesystem backend, SQLite backend, or MySQL backend.
All pastes are being encrypted on the fly and can only be retrieved by an
authorized user, either through knowing the paste id of a public paste, or
having authentication credentials, as well as the paste id of a private paste.
This makes httpaste ideal as a pastebin for sensitive environments such as the
Tor network. Authentication credentials are created on-the-fly and dont require a sign-up process.
Public data can be accessed through an URL, where as private pastes
additionally require HTTP basic authentication. Creation of authentication
credentials happens on the fly, there is no sign-up process. Public pastes can
only be accessed by knowing their paste ids, they are not listed on any index,
since it isnt technically possible (by design).
All pastes are symetrically encrypted server-side with an HMAC derived key and
SHA-256 hashing, a server-side salt and a randomly generated password. Public
pastes passwords are derived from their ids. Private pastes passwords are
randomly generated and stored inside a symetrically encrypted personal
database, with the encryption key also being derived through the same HMAC
mechanism, where the HTTP basic authentication credentials act as the master
password.
Paste ids, usernames, and any other identifiable attributes are only stored
inside storage backends as keyed and salted BLAKE2 hashes.
The program supports output formatting for syntax highlighting (powered by
httpaste supports output formatting for syntax highlighting (powered by
[pygments](https://pygments.org/)), as well as MIME type output manipulation, and input encoding.
The program can therefore serve as a minimalist, anonymous object storage for
small data.
Therefore httpaste can server as an anonymous object storage for small data.
Minute-based and burn-after-read paste expiration are also supported.
