AxCrypt Premium includes a sleek, modern appearance, and when it's active you will barely notice it. Documents in its own Secured Folders become encrypted when you sign outside, and it is one of those 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 to you. Your documents are encrypted, split into chunks, and tokenized. Then each chunk gets saved 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 access 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.

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

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

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

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

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

wUwDPglyJu9LOnkBAf4vxSpQgQZltcz7LWwEquhdm5kSQIkQlZtfxtSTsmawq6gVH8SimlC3W6TDOhhL2FdgvdIC7sDv7G1Z7pCNzFLp0lgB9ACm8r5RZOBiN5ske9cBVjlVfgmQ9VpFzSwzLLODhCU7/2THg2iDrW3NGQZfz3SSWviwCe7GmNIvp5jEkGPCGcla4Fgdp/xuyewPk6NDlBewftLtHJVfPAb3

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

Whether its in transit such as our hot dog party email or resting on your own hard drive, encryption functions to keep prying eyes out of 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 data, you can read our article on how encryption helps cloud safety. .

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

Popular Virtual Currencies for Dummies

Triple DES was designed to replace the original Data Encryption Standard (DES) algorithm, which hackers eventually learned to defeat with relative ease. At one time, Triple DES has been the recommended standard and 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 experts would assert that 112-bits in key strength is more like it.

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

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

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

Not known Facts About Top 5 Virtual Currencies

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

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

Blowfish can be found in applications classes ranging my link from e-commerce platforms for securing payments to password management tools, where it used to safeguard 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 considered 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. Because of this, youll find it bundled in encryption applications such as PhotoEncrypt, GPG, and the popular open source software TrueCrypt. .
