I'm happy to announce the first version of stackage-upload. Copied below is the content of the README file; if you see errors please send a pull request to update the content. This tool is pretty simple right now, but can be easily extended. If others are interested in collaborating on this project, please be in touch.
stackage-upload provides a more secure version of the
cabal upload command
by using HTTPS. When uploading a package to Hackage,
cabal upload will
perform the upload in plain-text via unencrypted HTTP, using basic
which is vulnerable to both man in the middle (MITM) and eavesdropping attacks
(anyone sniffing your packets can get your username and password). This package
instead uses secure HTTPS to upload to avoid both of these attacks.
To install, simply run
cabal update && cabal install stackage-upload. Usage
is quite similar to
cabal upload: just call
stackage-upload and pass in a list
of tarballs to upload. (If you have
stackage-cli installed, you can call
stk upload instead.)
stackage-upload --help will provide full options.
I'd be happy to add TLS support to cabal-install directly (using Vincent's
tls package), but the two last times this topic came up, I have been unable
to find a proposal that is acceptable to the Cabal project (mostly around
Haskell Platform requirements). I made an open offer to send the pull request
myself to move cabal-install over to http-client to get TLS support (either via
http-client-tls or http-client-openssl).
This tool was something that I (Michael Snoyman) wrote for myself a while back,
and decided to rebrand as
stackage-upload when the severity of the insecure
upload situation became apparent to me, and it became obvious that there was no
path forward for getting
I actually consider this situation to be so dangerous that I would like to ask the Hackage Server team to consider turning off insecure uploads to Hackage. The current possibility for corrupted uploads to infect all users of a package is alarmingly high.
