In essence, encryption is a method of encrypting data and information into a form that can only be decrypted by the parties that have the keys. This can be done with various mathematic models and is utilized every day to protect the information and data that consumers and businesses utilize in their everyday lives.
Modern encryption algorithms play an important part in ensuring the confidentiality of digital data stored on computers or transmitted over networks like the internet. It also facilitates security measures such as authentication (verifying the source of a message) as well as integrity (ensuring that it has not been altered) and non-repudiation (the ability to prove that an individual or company actually sent a message).
Algorithms are utilized to convert plaintext into encrypted text. The encrypted text can only be read using a decryption code which is a secret password, or a sequence of numbers that the sender as well as the recipient have agreed on. The more secure the cryptographic keys, the more difficult it is for third-party users to identify using brute force methods.
Many privacy and security laws require robust encryption to ensure that private data is secure and private. Many individuals and businesses utilize encryption to protect their folders, files, and entire computers with software programs such as 7-Zip or CertainSafe, and they can also protect their entire hard drive in the cloud with virtual private networks. Many companies offer multiple encryption solutions to provide the strongest security.
