This adds a proof-of-work based scraper deterrence to GoToSocial's middleware stack on profile and status web pages. Heavily inspired by https://github.com/TecharoHQ/anubis, but massively stripped back for our own usecase. Todo: - ~~add configuration option so this is disabled by default~~ - ~~fix whatever weirdness is preventing this working with CSP (even in debug)~~ - ~~use our standard templating mechanism going through apiutil helper func~~ - ~~probably some absurdly small performance improvements to be made in pooling re-used hex encode / hash encode buffers~~ the web endpoints aren't as hot a path as API / ActivityPub, will leave as-is for now as it is already very minimal and well optimized - ~~verify the cryptographic assumptions re: using a portion of token as challenge data~~ this isn't a serious application of cryptography, if it turns out to be a problem we'll fix it, but it definitely should not be easily possible to guess a SHA256 hash from the first 1/4 of it even if mathematically it might make it a bit easier - ~~theme / make look nice??~~ - ~~add a spinner~~ - ~~add entry in example configuration~~ - ~~add documentation~~ Verification page originally based on https://github.com/LucienV1/powtect Co-authored-by: tobi <tobi.smethurst@protonmail.com> Reviewed-on: https://codeberg.org/superseriousbusiness/gotosocial/pulls/4043 Reviewed-by: tobi <tsmethurst@noreply.codeberg.org> Co-authored-by: kim <grufwub@gmail.com> Co-committed-by: kim <grufwub@gmail.com> |
