Thought people might be interested in seeing a project I’ve almost completed.
Purplix.io is a open source end-to-end encrypted survey system & warrant canary manger / viewer.
Would love some feedback or to answer any questions anyone has!
(Ignore the Nav not expanding to the bottom on some of the screenshots, thats just due to the screen shotting tool i use for full page screenshots.)
When you say end-to-end encrypted, what are you referring to?
What’s the intent for this tool that isn’t solved via TLS?
Also, just as an aside, but this is kind of funny given the context:
I’m going to assume whoever is hosting the service can’t view your surveys and results.
E2EE meaning survey questions and answers are encrypted locally & decrypted locally. The server or any other actors can’t view survey questions aside from users its shared with and survey answers are only readable by the owner of such survey.
This means on a data leak, nothing is readable.
Yea Purplix.io is still in development, so it isn’t live yet. Hense the fail DNS lookup you show.
Excellent work! I’ve been looking for something like this for AGES
How does in compare to https://cryptpad.fr?
Don’t know the complete inner workings of Cryptpad. But it appears Purplix uses more modern encryption, uses more modern frameworks & has more safe guards against MITM attacks. Also additional options like captcha, proxy block, account required etc.
Looks pretty cool
Where is the data stored? Is it encrypted at rest?
No, survey questions and answers are encrypted & decrypted locally. At no point does the server or any other actors can view that plain data said from whom the survey is intended for.
I understand encrypted-at-rest to mean that the data is always stored under encryption, except when it is being actively being used or displayed. Am I wrong? So in your usecase also, all data is stored under encryption and only decrypted by the surveyor or the surveyed; so this is encrypted at rest, no?
Encrypted at rest doesn’t always mean E2EE. For example if data is transmitted in plain text to the server and then encrypted before storage. This is still encrypted at rest.

Yea I’d love to have Paaster audited, currently I don’t think its likely I’d get enough funding to do so as auditing is expensive.
