"Tonika is a routing and security infrastructure for fully independent distributed social networks. Users of Tonika are equal citizens in a private and secure Internet of their own. Every user obtains a permanent anonymous URL, under which they can publish content or services. Low-level physical message exchange occurs only between pairs of related users in an encrypted and authenticated fashion. Yet, a novel routing algorithm allows for establishing anonymous and encrypted communication between any pair of users (specified by their URLs), in a manner that scales to billions."

It's strange the things people will decide to crack.

An online notebook (like SimpleNote) which encrypts all your notes. Encryption/Decryption is done on the client side, so the web service doesn't know what you are storing.

I can\'t listen to this at work, my computer has no sound, but I suspect it will be awesome.

Every so often I\'ll harass everyone I know to start using PGP or something similar to encrypt all their mail. That goes over really well.

\"The NULL encryption algorithm offers no confidentiality nor does it offer any other security service.\"

It does what the name says. (Though these are passwords you won\'t be able to remember.)

This is a really neat idea.

There is lots of information on cryptography here.

Now you can find collisions at home.

There is something a little less cool about the NSA when they have a kids web page.

Links to some papers and some basic details on the attacks on SHA-1.

The paper describing the break of SHA-1 is now available.

My hope is that if I keep linking to crap like this everyone I know will start encrypting their mail.

You have got to be fucking kidding me.

The guy recovered complete AES keys used by OpenSSL. It\'s an interesting paper.

Apparently this software allows for secure file-sharing.

Damn.

Good advice for everyone, not just OS X users.

A great list of articles on anonymity and privacy on the Internet.

Simple trick to complicate network monitoring.

Damn -- apparently Quantum Mechanics isn\'t all bullshit. I might owe Ju-lian a pop or something.

Looks like an anonymizer for all your internet surfing needs.

Encryption, Authentication, Deniability, and Perfect Forward Secrecy. Oh baby.

PGP attempts to make a better keyserver for storing your OpenPGP public keys.

A fairly straight forward survey on provable security, co-authored by my old cryptography professor.

From what I\'ve read so far a pretty good introduction to Cryptography.

Lecture notes on the subject at the bottom of the page.

Bruce Schneier writes about security in Blog form.

Friends, strangers, people stumbling on this site by accident, start using public-key crypto already.

This is a much bigger deal then the SHA-0 break.

An interesting paper by Microsoft on DRM.

A really great outline of the problems with DRMs.
