I have used Peerblock for quite a while now, not only as a means to download torrents securely, but to also remove ads from web pages and things I don’t want to see in general like those annoying video ads on web sites.
The way peerblock works is that it filters all the connections coming in or out of your computer, and lets you choose from a list of blacklists if you want to block things like copyright enforcement agencies, hackers, things like that. It is very configurable, runs in the background, and takes great logs.
Hackers and free-speakers the world over are gushing about the new 100% fully encrypted web-chat CryptoCat. Messages are encrypted inside-browser with AES-256 and 4096-bit asymmetric keys. Encrypted data is securely wiped after one hour of inactivity.
CryptoCat is an easy way to create an anonymous chat, send someone the link, and be chatting securely, and 100% encrypted, in no time flat. There is also a Chrome Browser plugin that affords the same functionality for CryptoCat that Google Talk uses, with desktop notifications running smooth as butter.
CryptoCat is a project by a group of hackers led by 21 year old Lebanese ex-pat hacker, Nadim Kobeissi. After being interrogated several times as a youngster by his own government, he yearned for a way to speak with his friends, unimpeded, and without fear of ending up in another shadowy room tied to a chair. He previously worked with The Guardian Project to create an app to encrypt android smartphones by using the tilt sensors to randomize an encryption key, and allowing you to, as he described it, “Dance with your phone to encrypt it”.
The chat site imposes a 256 character limit on outgoing chat messages, a limit of 10 people per room, and people are invited simply by sharing a URL. To create your own private chat, you can just visit the main site, add a room name and you are ready to go! The site can be accessed over normal internet, or by darknet, at the onion hidden service URL which is hidden somewhere in the code of this article (you can find the URL somewhere else, but I just wanted to make it more fun for you guys)
We have created a demo chat here at GeekBlogTV as a proof of concept.
