VoIP Encryption in a Surveillance Society March 7, 2007 lecture by Phillip Zimmermann for the Stanford University Computer Systems Colloquium (EE 380). Phil talks about how the debate on the use of crypto has shifted since the 1990s, when it was a clash between civil liberties and law enforcement - in the 1990s, the crypto debate was about averting omniscience in governments, but today the encrypted VoIP debate may be about averting omniscience in criminals.

How To Make an Unbreakable Encrypted USB Drive With Hidden Volumes [ geekblog.tv ] Today we will be setting up a USB Drive to thwart any Police efforts to search your private data, and to help you get away red-handed. What we will be doing is creating an encrypted block on a USB thumb drive with an invisible encrypted block inside of it that is undetectable, and unbreakable by police. The block has two passwords, one that leads to bogus, fake info, and one that leads to the properly decrypted file that contains all of your deepest secrets.

How to encrypt your emails This tutorial will show how you can encrypt your E-Mails by following just a few steps. Don't forget to check out our site howtech.tv for more free how-to videos! - our feed - join us on facebook - our group in Google+ Encrypting your E-Mails is a very simple and easy task. We will be using "Thunder Bird" which is a free E-Mail application that's easy to set up and customize - and it's loaded with great features! Apart from that we will also look over "Enigmail" which is one of the Thunderbird extensions that helps you to secure emails. It enables you to write and receive E-Mail messages signed and/or encrypted with the OpenPGP standard. Sending and receiving encrypted and digitally signed E-Mail is simple using Enigmail. "Pretty Good Privacy" (PGP) is a data encryption and decryption computer program that provides cryptographic privacy and authentication signing, encrypting and decrypting texts, E-mails, files, directories and whole disk partitions. Prior jumping to encrypting E-Mails you must know the terminologies as "PUBLIC KEY", "PRIVATE KEY" and "DIGITAL CERTIFICATES". Public key is the key to lock or encrypt the plain text, and where as private key is to unlock or decrypt the cipher text. Public key is published over servers or send to intended person via E-Mail via private key is kept secret. Neither key will do both functions. A digital signature is basically a way to ensure that an e-mail is authentic and it has not ...

Gambling with Secrets: Part 5/8 (Encryption Machines) Explore how the one-time-pad was applied during WW2 with the use of rotor encryption machines. The German's Enigma machine would have been nearly impossible to break if it didn't rely on human operators making "random" choices. This video purposely ignores many details of the Enigma (such as the plug-board) and how it was broken. The goal is to explain the strength of the machine in terms of the key space. Also, pseudorandom sequences (no matter how you generate them) require a random initial seed. This will be fleshed out in the final chapter on Public Key Cryptography.

Python Backdoor - AES Encrypted Traffic What's up! Today, we're gonna be picking up where we left off last time in "Programming a Custom Backdoor in Python", so I hope you have seen that before reading this or you will be pretty lost. LOL For this episode, we're gonna be implementing AES encryption to our custom backdoor... so not only is our executable completely undetectable, but now it's traffic is also secured. Think about it, traffic on port 443 is always encrypted anyway. Credits go out to Koala's Code for the AES encrypt/decrypt functions, link can be found in full article below!

Computer File Encryption : Part I Computer File Encryption : Part I. The sophistication of computer network intruders and computer hackers seem to exponentially grow by the day. In an earlier episode of The Communicator, Jeff, Chris, and Brittany talked about password security, which is one of multiple levels of computer security that should be implemented. In this episode, Jeff and Chris outline the need for File Encryption - the process of transforming information using an algorithm to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The reverse process to make the encrypted information readable again is referred to as decryption. In Part II, Jeff and Chris will be talking about file encryption options.

MCTS 70-680: Encrypting File System (EFS) The Encrypting File System (EFS) is used in Windows to encrypt files so they cannot be read even using an offline attack. In order to ensure you can always access encrypted files, Windows allows a DRA to be created. A DRA is anther user that can access any files encrypted. This video looks at how the encrypted file system works and how to configure a DRA. 03:11 demo on how to encrypt files 05:52 exporting the EFS certificate using cipher /r:filename 06:22 Configuring a DRA using group policy HKEY\Computer configuration\Windows Settings\Security Settings\Public Key Polices\Encrypting file system How EFS works A file is encrypted with a symmetric key. This is the same style of algorithm used to secure compressed files like zip. The same password or key is used to encrypt the file as decrypt the file. The symmetric key is randomized for each file and thus you need some where to store all these symmetric keys. The easiest place to store the symmetric key is in the file itself. That way if the file is moved to a different computer or hard disk the key is always present with the file. In order to make sure that the symmetric key is stored in the file can't be read, the symmetric key is encrypted using an EFS certificate. An EFS certificate is generated for the user when they encrypt there first file or by running the command cipher /k. In a domain environment you can also configure a certificate authority to create and manage these certificates. This essentially means the ...

Absolute Poker Network Encryption Vulnerability The Cereus poker network uses a weak xor based encryption mechanism for all network transmissions instead of the industry standard SSL. The encryption key can be easily identified from a network dump and used to decrypt all information transmitted between the client application and the Cereus servers. In our lab we are able to intercept and decode the user's login name (e-mail address), and receive an MD5 hash of their password, as well as their seat number and hole cards. Once the MD5 password hash has been intercepted, we've been able to log in using the intercepted login name by overwriting the outgoing login packet with the intercepted MD5 hash - thus logging in the victim's poker account without their knowledge, remotely. We've also been able to remotely display all seat numbers and hole cards on a compromised network. All proof of concepts have been shown to work over a compromised WPA2 encrypted wireless network as well as unencrypted wireless networks, and physical network access (either through a hub, ARP man in the middle attack, or otherwise).
