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

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

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

The other products here 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 programs reviewed here, or a favorite tool we didn't mention Let us know in the comments. .

While security is an afterthought for many PC users, its major priority for most 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 lots of forms of security technology available, however, encryption is one that regular computer users should know about.

Encryption is an interesting piece of technology that is employed by scrambling data so it is unreadable by unintended parties. Lets take a peek at how it works 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 one of those programs. Heres the message:

Once encrypted, the message literally becomes a jumbled mess of random characters. However, equipped with all the secret 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 works to keep prying eyes from your business even when they happen to somehow gain access to your network or system.  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 overcome with relative ease. At one time, Triple DES was the recommended standard and the most widely 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 experts would argue that 112-bits in key strength is 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 also the standard for encrypting data sent over the internet. Additionally, it happens to be one of the 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. moved here 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 takes 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 categories ranging from e-commerce platforms for securing payments to password management programs, in which 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 may 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 publicly available to anyone who wants to utilize it. Because of this, youll find it bundled in encryption applications such as PhotoEncrypt, GPG, and the popular open source software TrueCrypt. .
