Everything about Top 5 Virtual Currencies

AxCrypt Premium has a sleek, modern appearance, and when it's busy you'll hardly notice it. Files in its Secured Folders get encrypted automatically when you sign out, and it's one of those few which support 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 documents are encrypted, split into chunks, and tokenized. Then each chunk becomes saved on a different server. A hacker who violated one server could get nothing useful. .

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

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

There are several kinds of security technology available, however, encryption is one that regular computer users should know about.

Encryption is an interesting bit of technology that works by scrambling data so it's unreadable by unintended parties. Lets take a peek at how it functions with the email-friendly software PGP (or GPG for you open source people).

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

Once encrypted, the message actually becomes a jumbled mess of random characters. But, equipped with the key passcode I text you, 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 works to keep prying eyes out of your business even if they happen to somehow gain access to a network or platform.  If you want to learn more about how encryption helps protect business data, you can read our article on how encryption helps cloud security. .

The technology comes in many forms, with key size and strength generally being the biggest 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 defeat with comparative ease. At one time, Triple DES has been the recommended standard and also the most commonly used symmetric algorithm in the industry.

Triple DES uses three individual keys with 56 bits each. The total key length adds up to 168 bits, but specialists would argue that 112-bits in key strength is published here much similar to 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 used in our PGP and GPG programs.

Unlike Triple DES, RSA is considered an asymmetric algorithm due to its use of a pair of keys. Youve got your public key, which is 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 splits messages into blocks of 64 bits and encrypts them individually.

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

Blowfish can be found in software classes ranging from e-commerce platforms for securing payments to password management programs, in which 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 software TrueCrypt. .
