Overview Of Encrypted Data
Data commonly appears in plain text or clear text form. For a number of reasons, it sometimes becomes necessary to hide or disguise the data. During such circumstances, people choose to encrypt the information to protect it from hackers and other unauthorized users. Encrypted data is unreadable as the process of encryption converts the clear text into cipher text hence preserving the integrity of the file. Data encryption is typically performed by businesses and corporations who have sensitive data to store and protect against unintended recipients.

How it Works

The way in which data encryption is achieved is the sender provides a password to the intended user in a discrete email or via a secured phone line. When the user obtains the encrypted data, he/she will have to use the provided password to decipher the code back to its normal clear text form.

To encrypt and decrypt covert messages, one must use the method of cryptography. It employs mathematics to store sensitive data. A computer user can transfer the coded data through an unsecured connection without worrying that the content will be compromised. A scientific formula known as "cryptographic algorithm" runs in combination with a code, which can be either a number combination or a phrase, to encrypt the data. The plain text can be converted into cipher text using various keys. Employing a dynamic cryptographic formula and keeping the password in secrecy are imperative steps for the entire process to work.

Types of Encryption

There are different types of encryption. The ubiquitous browser and email encryptions are the most usual types. Browsers automatically hide information through a secure server. The encrypted domain has the traceable address starting with HTTPS, with the "S" connoting secure. The server then decodes the information when it arrives. For emails, the function of PGP is the normal encryption chosen. This hides private messages, sensitive documents, and folders.

Encrypting a hard drive is another common form of encryption. This maintains the security and integrity of sensitive information. Comprehensive hard disk drive encryption, restriction of user operator encryptions, and creation of an individual encrypted virtual drive that solely constitutes of hidden data are the three techniques for encrypting a hard drive.

Why Encryption?

Why Encryption?
Encryption has long been performed by government agencies and military forces to carry out covert communication. Today, it is also used by civilians and commercial groups to facilitate data security. In previous years, there have been multitude reports of sensitive information like client's personal records being accessed and used via lost ot stolen laptops or external hard drives. By encrypting data stored in your computer, you are protecting yourself in case tactile security protocols are unsuccessful. Another good example of encrypting data at rest is that of Digital rights management systems that avert unintended access or reproduction of copyrighted content and safeguard programs against reverse engineering.

Though encryption can individually protect the secrecy and confidentiality of files and documents, there are other methods still needed to achieve maximum security for your data; for instance, a MAC, short for message authentication code, confirmation and/or a digital signature. Keep in mind that advance hackers and cryptographers can still access and use messages without decrypting it, usually through specialized techniques and software like Tempest and Trojan Horse.
