Top 5 Virtual Currencies for Dummies

AxCrypt Premium includes a sleek, modern appearance, and when it's active you will hardly notice it. Files in its Secured Folders become encrypted when you sign out, and it's one of the few which encourage public key cryptography.

CertainSafe Digital Safety Deposit Box goes via a multistage security handshake that authenticates you to the website and authenticates the site for you. Your files are encrypted, split into chunks, and tokenized. Then each chunk becomes saved on a different server. A hacker who violated one server would get nothing useful. .

Folder Lock can either encrypt files or lock them so nobody can access them. Additionally, it supplies encrypted lockers for secure storage. Among its many other characteristics are file shredding, free space shredding, secure online backup, and self-decrypting files.

The other products here also have their merits, too, naturally. Read the capsules below and then click through to the full reviews to decide which one you'll use to protect your files. Have an opinion on one of the apps reviewed , or a favorite tool we didn't mention Let us know in the comments. .

While security is an afterthought for many PC users, its a major priority for most businesses of any size. It must be when the Ponemon Institute tells us that security breaches are costing companies millions each year.

There are several forms of safety technology available, however, encryption is one that regular computer users must know about.

Encryption is an interesting piece of technology which works by scrambling data so it's unreadable by unintended parties. Lets take a look at how it functions together with the email-friendly applications PGP (or GPG for you open source folks ).

Say I want to send you a personal message, so that I encrypt it using either one of those programs. Heres the message:

Getting The Popular Virtual Currencies To Work

Once encrypted, the message literally becomes a jumbled mess of random characters. However, equipped with the key passcode I text youpersonally, you can decrypt it and find the original message.

Whether in transit such as our hot dog party email or resting on your own hard drive, encryption functions to keep prying eyes from your business even when they happen to somehow gain access to your network or platform.  If you want to learn more about how encryption helps protect business information, then you can read our article on how encryption aids cloud safety. .

The technology comes in many forms, with key size and strength generally being the biggest differences in one range from the next.

Triple DES was designed to replace the original Data Encryption Standard (DES) algorithm, which hackers eventually learned to defeat with comparative ease. At one time, Triple DES has been the recommended standard view it and also the most commonly used symmetric algorithm in the industry.

Triple DES uses three individual keys with 56 bits each. The whole key length adds up to 168 bits, but specialists would argue that 112-bits in key strength is more like it.

Despite gradually being phased out, Triple DES still manages to earn a dependable hardware encryption solution to financial services and other industries.

RSA is a public-key encryption algorithm and the standard for encrypting data sent over the internet. Additionally, it happens to be one of those methods utilized in our PGP and GPG applications.

Unlike Triple DES, RSA is considered an asymmetric algorithm due to its usage of a set of keys. Youve got your public key, which is what we use to encrypt our message, and a private key to decrypt it. The result of RSA encryption is a huge batch of mumbo jumbo that requires attackers quite a bit of time and processing power to break. .

Blowfish is yet another algorithm designed to replace DES. This symmetric cipher splits messages into blocks of 64 bits and encrypts them individually.

Blowfish is known for the tremendous speed and total effectiveness as many claim it has never been defeated. Meanwhile, vendors have taken full advantage of its free availability in the public domain.

Blowfish can be found in applications classes ranging from e-commerce platforms for securing payments to password management programs, where it used to protect passwords. Its definitely one of the very flexible encryption methods available.

Computer security expert Bruce Schneier is the mastermind behind Blowfish and its successor Twofish. Keys used in this algorithm might be up to 256 bits in length and as a symmetric technique, only one key is needed.

Twofish is regarded as one of the fastest of its kind, and ideal for use in both hardware and software environments. Like Blowfish, Twofish is freely available to anyone who wants to use it. As a result, youll find it bundled in encryption programs like PhotoEncrypt, GPG, and the popular open source applications TrueCrypt. .
