How Top 5 Virtual Currencies can Save You Time, Stress, and Money.

AxCrypt Premium has a sleek, modern look, and when it's active you'll hardly notice it. Files in its Secured Folders get encrypted when you sign out, and it's one of the few that encourage public key cryptography.

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

Folder Lock can either encrypt files or simply lock them so nobody can get them. It also offers encrypted lockers for storage. Among its many other features are file shredding, free space shredding, secure online backup, and self-decrypting documents.

The other products here also have their merits, too, naturally. Read the capsules below and then click through to the full reviews to choose which one you'll use to safeguard 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 informs us that security breaches are costing companies millions each year.

Getting The Popular Virtual Currencies To Work

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

Encryption is an interesting piece of technology that works by scrambling data so it is unreadable by unintended parties. Lets take a look at how it works with the email-friendly software 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 these apps. Heres the message:

The Buzz on Popular Virtual Currencies

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

Whether its in transit such as our sexy dog party email or resting on your hard disk, encryption functions to keep prying you can check here eyes out of your business even if they happen to somehow gain access to your network or system.  If you want to learn more about how encryption helps protect business data, you can read our article on how encryption aids cloud security. .

The technology comes in many types, with key dimensions and strength generally being the largest differences in one variety from the next.

Triple DES was designed to replace the original Data Encryption Standard (DES) algorithm, which hackers eventually learned to overcome with relative ease. At one time, Triple DES has been the recommended standard and also the most widely 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 much similar to it.

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

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

Unlike Triple DES, RSA is considered an asymmetric algorithm as a result of its use of a set of keys. Youve got your public key, and that's what we use to encrypt our message, and a private key to decrypt it. The consequence 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 divides messages into blocks of 64 bits and encrypts them individually.

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

Blowfish can be found in software 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 elastic encryption methods available.

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

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