CryptPad

Zero knowledge, collaborative, real time editing of WYSIWYG and text documents, and now polls, with...

CryptPad is a private-by-design alternative to popular office tools and cloud services. All the content stored on CryptPad is encrypted before being sent, which means nobody can access your data unless you give them the keys.

CryptPad is a suite of zero knowledge, realtime collaborative editors and applications. Encryption carried out in your web browser protects the data from the server, the cloud, and the NSA. The secret encryption key is stored in the URL fragment identifier which is never sent to the server but is available to javascript so by sharing the URL, you give authorization to others who want to participate.

CryptPad uses a variant of the Operational transformation algorithm which is able to find distributed consensus using a Nakamoto Blockchain, a construct popularized by Bitcoin. This way the algorithm can avoid the need for a central server to resolve Operational Transform Edit Conflicts and without the need for resolving conflicts, the server can be kept unaware of the content which is being edited on the pad.

Cryptpad offers collaboration on text and WYSIWYG documents, as well as a basic polling application where users see results in real time.

  • Google reverses 5M file limit in Google Drive
    It's not LibreOffice, but while revisiting CryptPad (which I thought was a multiplayer notepad like etherpad or codimd, except with an encryption key in the url fragment identifier) I was impressed to see that they're expanding to become an entire office suite. You get a WYSIWYG editor (I'd rather wish for markdown but ok), spreadsheet editor, survey forms, and more which I don't remember, all live like google... - Source: Hacker News / about 2 months ago
  • suckless collaborative text editing like google docs
    Currently I'm looking at https://cryptpad.org/. But maybe there is an alternative that sucks even less?! - Source: Reddit / 2 months ago
  • Daily General Discussion - February 13, 2023
    I hear ya, I’m still running Desqview on this 8088. Sooo… I’ve got something awesome in store for us. Cryptad. Cryptad is a open source, browser based, self hosted, end to end encrypted office suite. For free! - Source: Reddit / 4 months ago
  • Is zero-knowledge hosting a thing?
    I know about privatebin and cryptpad projects. They both provide (at least it is an option) zero-knowledge file hosting. For example, privatebin server doesn't know the contents of my paste, only my friend with a link can open this file. The link itself is a decryption key. - Source: Reddit / 5 months ago
  • Libreoffice vs Onlyoffice spreadsheet for a newbie
    Another reason I was pleased with Only Office was due to the https://cryptpad.fr/ support. -- https://docs.cryptpad.org/en/FAQ.html#faq-oointegration. - Source: Reddit / 5 months ago
  • Pastebin for spreadsheet documents??
    Try cryptpad. I've used it as a google docs alternative and it got the job done. It seems to support spreadsheets as well, but I can't test the mentioned formats on a phone. (It says Your browser cannot handle conversion to and from office formats.). - Source: Reddit / 5 months ago
  • Participate in r/Jordan’s 2022 census!
    Also, Google forms? Do yourself a favor and use NextCloud Forms or Cryptpad Forms. - Source: Reddit / 5 months ago
  • Note-taking app for programmers/tech people?
    I think CryptPad is a good option for collaborative work. - Source: Reddit / 5 months ago

  • Smart Move, Google
    You might want to check out: https://framapad.org/abc/ (this organisation has a lot of FLOSS cloud alternatives to Google products) https://cryptpad.fr/. - Source: Hacker News / 6 months ago
  • France bans Office 365 and Google Docs from schools and public administration
    Https://cryptpad.fr if you want to use something in the cloud which respects privacy more. But I think the more practical solution is LibreOffice/OpenOffice. I think it's encouraged (or even enforced?) to use that office suites for public service/government institutions in France. - Source: Hacker News / 6 months ago
  • Looking for project purchase list tracking tool
    I think there's several possible solutions: * No-code/low-code database platforms (e.g., NocoDB) * Personal finance manager (e.g., Firefly III) * Spreadsheets (e.g., CryptPad for a full office suite or Ethercalc) * Task management systems (e.g., Vikunja). - Source: Reddit / 6 months ago
  • Any recommendation for FOSS alternative to Google Docs.
    There is a free offer on the official instance, you should check out the other public instances. - Source: Reddit / 7 months ago
  • Request for some personal advice: How could programming skills contribute to mutualist causes?
    I'd also recommend looking into anything to do with open source, peer-to-peer networks, end-to-end encryption, federation or platform co-operatives. For example: Matrix, Freenet, Cryptpad, Activity Streams, Mastodon, Aether, Scuttlebutt and Resonate. A whole plethora of services from video conferencing to online marketplaces to crowdfunding platforms to streaming platforms can be built using similar principles and... - Source: Reddit / 7 months ago
  • Estimating the Hurst exponent of GME to detect coordinated movements in the stock
    Hey there! As far as a dataset uploader I like CryptPad - they're funded in part by the Mozilla Foundation and are open source. Solid crytography in the tool too. https://cryptpad.fr/ / https://cryptpad.org. - Source: Reddit / 7 months ago
  • Good idea to host business email/calendar/Drive on Proton Business?
    For document collaboration, I find CryptPad fairly capable, and probably the closest you currently get to an E2EE based alternative to Google Docs. - Source: Reddit / 8 months ago
  • These things happen when I install spell checker and grammar correction software addon "LanguageTool" to Libreoffice. After several attempts, this addon doesn't install or work in LO. Using the latest version "7.4.0.3" on W10.
    I noted both LO team and LT team, but none of them are looking as why there is such an issue when that addon is made for LO. Anyway, downloaded latest but didn't work. Unfortunately, I have to https://cryptpad.fr/ to work online and use LT as addon until this doesn't gets resolved. - Source: Reddit / 8 months ago
