How HTTP Works. Before diving into how HTTPS works, let's review how HTTP works. HTTP is a request response protocol to communicate asynchronously between client and server. For websites and pages the browser acts as a client and a web-server like Apache or IIS acts as server.

Jul 15, 2019 · Data encryption defined in Data Protection 101, our series on the fundamentals of data security. A Definition of Data Encryption Data encryption translates data into another form, or code, so that only people with access to a secret key (formally called a decryption key) or password can read it. The Data Encryption Standard (DES / ˌ d iː ˌ iː ˈ ɛ s, d ɛ z /) is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for applications, it has been highly influential in the advancement of cryptography. Transparent Data Encryption can be applied to individual columns or entire tablespaces. Topics: About Transparent Data Encryption Types and Components. How Transparent Data Encryption Column Encryption Works. How Transparent Data Encryption Tablespace Encryption Works. How the Keystore for the Storage of TDE Master Encryption Keys Works Encryption is also used to protect data in transit, for example data being transferred via networks (e.g. the Internet, e-commerce), mobile telephones, wireless microphones, wireless intercom systems, Bluetooth devices and bank automatic teller machines.

Data encryption works through a coding process to prevent documents, email messages, and other types of information from being accessed by unauthorized users. In an age of increased use of PC technology and sophisticated hackers, it is very easy for others to intercept your messages and read confidential documents.

The data encryption standard (DES) defined by US NIST performs encryption in hardware thereby speeding up the encryption and decryption operation. Additional features of DES are: 1. DES is a block cipher and works on a fixed-size block of data. The message is segmented into blocks of plaintext, each comprising 64 bits.

Aug 03, 2019 · A more modern 3DES is a version of block cipher used today. Triple Data Encryption Standard (3DES) works as its name implies. Instead of using a single 56-bit key, it uses three separate 56-bit keys for triple protection.

Jun 17, 2020 · Encryption helps protect information from data breaches, whether the data is at rest or in transit. For example, even if a corporate-owned device is misplaced or stolen, the data stored on it will most likely be secure if the hard drive is properly encrypted. Jul 08, 2019 · RSA is often used in digital signatures but works slower when large volumes of data need to be encrypted. 3. Triple Data Encryption Standard (TripleDES) Triple Data Encryption Standard is a symmetric encryption and an advanced form of the DES method that encrypts blocks of data using a 56-bit key. Encryption is the method of converting the data into a cipher format using a key. The encrypted data can be safely shared with others. It will be difficult to break the cipher format if the algorithm/key used is strong and properly implemented. The receiver deciphers the data to the original format using the key, used earlier to encrypt it.
