How exactly does data encryption work?

Encryption in general refers to the modern method of cryptography that lets users hide information from others. It does so by applying a complex set of algorithms called ciphers, which convert normal data (technically called plaintext) to what amounts to seemingly random characters (ciphertext). Only those who hold the key can decrypt the data and view them in plaintext anew.

Again, today’s encryption processes are based on old cryptography methods that create and decipher codes, tracing its origins back to ancient Greece. However, encryption in the internet age is done for a wide array of security measures, from protecting our private correspondences, personal information, and sensitive business data to keeping our credit cards, bank accounts, and social security numbers from being compromised.

In 1976, the U.S. National Bureau of Standards initiated the so-called Data Encryption Standard (DES), a shared secret encryption method or block cipher as the country’s official Federal Information Processing Standard or FIPS. Today, DES is being used more and more on a global scale.


Modern encryption essentially has two types: those that use symmetric key algorithms and those that apply asymmetric ones. Symmetric key algorithms use identical or related encryption keys for both encryption and decryption. On the other hand, asymmetric key algorithms have different or separate keys for encryption and decryption. Experts in the industry often refer to the latter as Public-key Cryptography.


The Agile Security Platform (ASP) of Secure Channels allows organizations to take a modular approach to better suit their needs, whether for securing access to critical resources or protecting client data from breach, theft, and misuse using the company’s patented Superencipherment solution.
