Passphrase.io - Zero knowledge notepad - Inspired by Bitcoin brainwallets

[devthedev]

Hi everyone. Inspired by Bitcoin Brainwallets, comes Passphrase.io



Enter a passphrase, type some text, and click save.

There is a multitude of uses for this website, such as storing sensitive information (passwords, private keys), sending secret messages to friends, or scavenger hunts. It can also be a social experiment to see how people modify the text for simple passphrases.

All data is encrypted in your browser, so plaintext contents of your passphrase or notepad can't be seen.  If you lose your passphrase, there is no recovery process.

For high security, create a long sentence that is difficult to guess and never used in any song, literature, or media.  Short phrases lead to high visibility, and text can be overwritten by anyone who stumbles upon it.

Technical details:  When you click save, your notepad is encrypted by your passphrase using AES256 encryption.  Then a SHA256 hash is run on your passphrase.  The hash and encrypted notepad is then sent to our server for storage.  We have no way of knowing your passphrase, and have no way of decrypting your notepad.  No data is ever stored in your browser, so when you close the website, no trace is left behind.

Let us know what you think!

Thanks! It's not, but in the future we may make it open source.

It's has changes hand to you?

BTW if you don't mind, maybe change the a text in second column be a transparant, like in first column. Just my opinion

We were in the the top page of /r/Bitcoin all day yesterday. Check it out!

Yes, I will be continuing development on this project.

Feel free to leave any suggestions or feature requests here.

You might want to polish the front end and add a few social media buttons so that people might share it, which gives passphrase.io some publicity

I like the idea generally and congratulation for the deal, I was also interested but decided to leave it. What I really don't like is some google code (analytics, adsense) on the page..

analytics:

Code:

<script>
		(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
		(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
		m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
		})(window,document,'script','//www.google-analytics.com/analytics.js','ga');

		ga('create', 'UA-64898721-1', 'auto');
		ga('send', 'pageview');
</script>

adsense:

Code:

<script type="text/javascript">
		google_ad_client = "ca-pub-4866156278966549";
		google_ad_slot = "7135381319";
		google_ad_width = 728;
		google_ad_height = 90;
</script

I'm not sure, if is suitable to use such spying services from google on so sensitive page, as this one is...please reconsider other option of collecting data (on server side and HTTP level like Webalizer) and some monetization (except adsense code inside). anyway, good luck with this project, idea is quite cool.

I will look for alternatives to Google services in the future.

That's a good thought, thanks!

Not problem,
How about some content which  emphasises the importance of the website and privacy?

Definitely, I'm trying to keep the home page as simple as possible. So I may lock passphrases such as "privacy" and "terms" and put emphasis on those things there.

Interesting project for sure, will try to provide some media coverage in the next few days.

Great Project ! In fact, We will try sending some marketing love your way whenever we are free !

guys, please keep in mind my post few lines above:

https://bitcointalk.org/index.php?topic=1113393.msg11863316#msg11863316

site itself is maybe cool and owner reputable, anyway, it contains 2 spying google scripts, which are able to suck almost all information about you just (analytics) by visiting site (broswer, country, age, interests, behavior, bounce rate and combined with adsense (yes, is possible to link those services together) - it is really deadly anti-private combo.

reconsider twice, if is smart to use such service for storing confidential and sensitive data. once owner will finally remove those spying third party features (and publish source code), I'll be ready to recommend it to use and propagate. until this moment, please stay away..

Fantastic, I would love that!

Hey there devthedev good luck with your new project! Do you have any plans for it?

Google Analytics as well as Adsense have been removed. I have replaced AdSense with a self hosted Piwik platform. Also, if you have Do Not Track enabled this will be honored and visits will not be tracked. No service will be replacing Adsense as I feel Passphrase.io should be solely donation supported. Source code will not be released for the time being, but it may be in the future.

Thank you! I appreciate it very much.

Thanks! We're still brainstorming about the future of the project. We're hoping to make this service the go-to for text storage in the cryptocurrency space.

Glad you like the article, and pleased to hear a solution to AdSense has been found
