I've released Hockeypuck 2.1.0
<https://github.com/hockeypuck/hockeypuck/releases/tag/2.1.0> [0], which
contains several new features that may be useful to mitigate
spamming/flooding/DoS [1] attacks on GnuPG and keyservers. See the
release link for details, but here's the highlights:
* Configurable key length and packet size limits, with sensible
defaults to limit keyserver resource consumption (1MB and 8K
respectively).
* Configurable blacklist of primary key fingerprints.
* Authenticated key management. This adds a couple of extra endpoints
which allow a key owner to replace and delete their key,
authenticated by signing the armored key in the request. This allows
a key owner to still update their own key once it has been inflated
beyond the key length limit.
Blacklists and auth key management may also be of interest to keyserver
operators subject to GDPR-related requests.
