Encryption is the process of converting data and information into a form which can only be decoded by the parties who hold the keys. This can be done with various mathematical models, and is used to secure data and information in the everyday life of businesses and consumers.
Modern encryption algorithms are vital for ensuring the confidentiality of data stored on computers or transmitted via networks like the internet. It also offers security measures such as authentication (verifying the source of the message), integrity (ensuring it’s not altered) and anti-repudiation.
Algorithms are employed to convert plaintext into encrypted text. The ciphertext can only be translated back into readable plaintext with a decryption code, which is a secret string of numbers or passwords that the recipient and the sender agree on. The more secure the cryptographic keys, the more difficult it will be for non-authorized third parties to decipher using brute force methods that include trying every possible string of characters.
Many privacy and security laws require the use of strong encryption to ensure that private information remains private and safe. Many businesses and individuals use encryption to safeguard files or folders as well as entire computers by using programs like 7-Zip and CertainSafe. They can also encrypt the entire hard drive on the cloud via virtual private networks. Additionally, several companies offer a variety encryption solutions that offer a variety of kinds of encryption to provide the most robust protection possible.
