In essence, encryption is the method of encrypting data and information into an encrypted form that can only be unlocked by the people who have the keys. This can be done with many mathematic models and is used every day to safeguard the information and data that consumers and businesses use in their everyday lives.

Modern encryption algorithms are crucial to ensure the security of digital information stored on computers or transmitted through networks such as the internet. It also offers security measures like authentication (verifying the origin of an email), integrity (ensuring it hasn’t been altered) and anti-repudiation.

Encryption works by converting plaintext that can be read by humans into an encrypted format, referred to as ciphertext by utilizing mathematical models called algorithms. The ciphertext is only readable by a decryption key, which is an encrypted password or sequence of numbers that the sender and the recipient have agreed upon. The more secure the keys are cryptographic, the more difficult it is for third parties to decipher using brute force methods.

Many privacy and security laws require a strong encryption in order to ensure that private information remains secure and private. Many individuals and businesses use encryption to protect files as well as entire computers with programs such as 7-Zip and CertainSafe. They can also secure the entire hard drive on the cloud using virtual private networks. Many companies provide multiple encryption solutions to provide the strongest security.
