About Popular Virtual Currencies

AxCrypt Premium has a sleek, modern look, and when it's active you'll barely notice it. Documents in its Secured Folders become encrypted when you sign outside, and it is 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 website and authenticates the website 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 useful. .

Folder Lock can either encrypt files or simply lock them so nobody can get them. It also 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, of course. 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 those programs reviewed here, or a favourite 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 businesses of any size. It has to be when the Ponemon Institute informs us that security breaches are costing companies millions every year.

There are several forms of security technology available, however, encryption is one which regular 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 functions together with the email-friendly applications PGP (or GPG for you open source people).

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

Once encrypted, the message actually 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 its in transit such as our sexy dog celebration email or resting on your hard drive, encryption functions to keep prying eyes out why not try these out of your business even when they happen to somehow gain access to a network or system.  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 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 was 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 total key length adds up to 168 bits, but experts would assert that 112-bits in key strength is much more like it.

Despite gradually being phased out, Triple DES still manages to make 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. It also recommended you read happens to be one of those methods used in our PGP and GPG programs.

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

Blowfish is still 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 overall effectiveness as many assert 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 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 perfect for use in both hardware and software environments. Like Blowfish, Twofish is freely available to anyone who wants to utilize it. As a result, youll find it bundled in encryption programs such as PhotoEncrypt, GPG, and the popular open source software TrueCrypt. .
