Encryption is the process of converting data and information into a form that can only be decoded and understood by those who possess the keys. This can be accomplished using an array of mathematical models and is used daily to protect the information and data consumers and businesses use in their daily lives.

Modern encryption algorithms are crucial to protect the confidentiality of data stored on computers or transmitted via networks such as the internet. It also supports security measures like authentication (verifying the origin of a message), integrity (ensuring that it has not been altered) and non-repudiation (the ability to prove that a person or business sent an email).

Algorithms are utilized to convert plaintext into ciphertext. The encrypted text can only be read with a decryption code, which is an encrypted password or sequence of numbers that the sender as well as the recipient have agreed on. The more secure the cryptographic keys is, the more difficult it is for unauthorised third parties to decipher using brute force methods like trying every possible string of characters.

Many privacy and security laws require robust encryption to ensure that private data remains secure and private. A lot of people and companies utilize encryption to safeguard files, folders and entire computers by using programs like 7-Zip and CertainSafe. They can also encrypt the entire hard drive in the cloud through virtual private networks. In addition, many businesses offer a variety of encryption options that offer multiple kinds of encryption to provide the most robust security possible.
