Re:Virginia has decertified its most hackable voting machines on Saturday September 09, 2017 @07:19PM (#15209623)

Another important property of voting systems is that you can't prove who you voted for, so that you can't be forced or paid to vote for someone. A blockchain based solution, even like ZCash does not fulfil this.

Companies often use noreply@… as sender and add a real address as Reply-To so their staff does not have to deal with bounce messages.

Yeah it's getting investigated, but it's not looking like there will be any consequences.

Is this really how the names are represented internally? if so, how can it tell apart e.g. "github.com/group_name/package" and "github.com/group/name_package"?

Re:Show HN: Forgiva – Never saves your passwords but regenerates them on Sunday October 02, 2016 @08:03AM (#12621988)

I wrote something similar some time ago: https://addons.mozilla.org/de/firefox/addon/masterkey/ https://github.com/ninov/masterkey-firefox

Or as android app: https://play.google.com/store/apps/details?id=de.ninov.maste...

It works by using SHA256-HMAC on the service name with your master key as key and then encoding it in Base85 or Base62 (if you don't want special characters)

Ask HN: Is derivating passwords from a master key and service name a good idea?

Posted by ninov on Wednesday January 14, 2015 @04:01PM
from the ask-hn dept.

Hi, I had an idea about generating passwords for different services (e.g. Hacker News, Facebook, Twitter, ...) by using a cryptographic hash of a master key chosen by each person and the services name, like this (python): import hashlib import base64 def password(masterkey, service): h = hashlib.sha256() # probably could use hashlib.hmac? h.update(bytearray(masterkey,...

I don't really get why you need to render this on a canvas. It's text only, you should be able to render this in pure HTML with some CSS.
