How To Add a Second Layer of Encryption to Dropbox [Updated]

How To Add a Second Layer of Encryption to Dropbox [Updated]
I started using BoxCryptor, which is mentioned in this thread. Free for up to 2Gb. Basically, it mounts an encrypted drive on your computer, and whatever you drop there gets encrypted and sent to another folder, which can be your Dropbox folder. If you're going to get your encrypted material somewhere else, you'll need BoxCryptor installed there as well. BoxCryptor can only be ran by system administrators. Another thing you can do is to encrypt files individually before dropping them on Dropbox. You can zip with 7Z via command line. I won't show how now, because I don't have the time... but I'm going to do it for myself sometime, then I can post it. [www.boxcryptor.com] Related:  Secure data and data transfer

Transfer Web Files Directly To Your Dropbox Folder With URL Droplet The Drops To The Cloud All the cloud services more or less work the same way – you upload your files to the cloud, and you can then access them from anywhere with an Internet connection. But things become impractical when the files you want to put in the cloud are also coming from the web. URL Droplet is the service that will cut out the middle man – your computer’s hard drive. To use URL Droplet, visit the site and click “Login“. Then you have to give permission to URL Droplet to connect to your Dropbox account. Let The Download Begin To download a file, you need the direct download link of that file to be pasted to the URL Droplet address field. For example, how can you save converted YouTube videos to your Dropbox account? You can also try another way to acquire the download address. Armed with the download address, go to the URL Droplet website and paste the link. The download progress can be monitored by looking at the bar. Have you tried URL Droplet? Image credit: wwarby

Public-key cryptography An unpredictable (typically large and random) number is used to begin generation of an acceptable pair of keys suitable for use by an asymmetric key algorithm. In an asymmetric key encryption scheme, anyone can encrypt messages using the public key, but only the holder of the paired private key can decrypt. Security depends on the secrecy of the private key. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key. After obtaining an authentic copy of each other's public keys, Alice and Bob can compute a shared secret offline. The shared secret can be used, for instance, as the key for a symmetric cipher. Public-key cryptography, also known as asymmetric cryptography, is a class of cryptographic algorithms which requires two separate keys, one of which is secret (or private) and one of which is public. Message authentication involves processing a message with a private key to produce a digital signature. Understanding[edit]

Dropbox Review for Lawyers By Geri L. Dreiling, Esq. Editor’s note: After this article appeared, Dropbox revised its terms of service and a complaint has been filed with the Federal Trade Commission against Dropbox over data security practices. Please read, “Dropbox in the Hot Seat.” For lawyers, having instant secure access to files and documents anywhere — in the office, during a deposition, at the library, at home or even on vacation — is a necessity rather than a luxury. To achieve that end, many lawyers are turning to cloud computing. Lawyer Tech Review recently surveyed attorneys who are using Dropbox to find out what makes the service attractive in the legal setting. Dropbox offers free accounts. Tasting samples and test drives are just a couple of ways in which we try before we buy. Cameron Dardis, a sole practitioner in Portland, Oregon who works in the areas of real estate law and criminal defense, began using Dropbox about seven months ago, beginning with the basic free account.

How To Encrypt Your Dropbox Data With ENCFS [Linux] Aside from the never-diminishing threat of a break-in by hackers, Dropbox has also said that it will turn over your data to the government if requested. This implies that, even if the data on their servers is encrypted (and not just the connection), they have a way to decrypt it and see what you’re storing. Although I’m sure most of you don’t have anything to hide, we feel more comfortable with some privacy. Therefore, encrypting the files before they are sent to the Dropbox servers is the way to go in order to keep eyes away. There are a couple different ways of achieving this, as of late. The Idea The technologies behind ENCFS are a pretty tricky to explain, so I’ll let you do that on your own time if you are interested. Installing To get started, you’ll first need to install ENCFS. install /path/to/gnome-encfs /usr/local/bin . Create your Encryption Setup Next, we’ll need to actually create the setup. encfs ~/Dropbox/.encrypted ~/Private . Next we need to automatically mount this setup.

InfoSec Handlers Diary Blog - Hashing Passwords After talking about SQL Injection, this is the second part of the mini series to help you protect yourself from simple persistent attacks as we have seen them in the last couple months. A common MO employed in these attacks is to steal passwords from a database via sql injection. Later, the attacker will try to use these passwords to break into other sites for which users may choose the same password. Of course, part of the problem is password reuse. First of all: What is hashing? Storing a password as a hash will make it difficult to figure out the actual password a user used. A hash isn't fool proof. Probably the most important defense against rainbow tables is the idea of introducing a "salt". In order to use a "salt", the salt value and the users password are first concatenated, then the string is hashed. Another trick to harden a hash is to just apply the same algorithm multiple times. Here a proposal to create difficult to reverse hashes with salt: ------ Johannes B.
