What is encryption and why is it important?
Encryption, is the process of changing information in such a way as to make it unreadable by anyone except those possessing special knowledge (usually referred to as a "key") that allows them to change the information back to its original, readable form.
Encryption is important because it allows you to securely protect data that you don't want anyone else to have access to. Businesses use it to protect corporate secrets, government’s use it to secure classified information, and many individuals use it to protect personal information to guard against things like identity theft.
Espionage uses encryption to securely protect folder contents, which could contain emails, chat histories, tax information, credit card numbers, or any other sensitive information. This way, even if your computer is stolen that data is safe.
Asymmetric cryptography is a branch of cryptography where a secret key can be divided into two parts, a public key and a private key. The public key can be given to anyone, trusted or not, while the private key must be kept secret (just like the key in symmetric cryptography).
Asymmetric cryptography has two primary use cases: authentication and confidentiality. Using asymmetric cryptography, messages can be signed with a private key, and then anyone with the public key is able to verify that the message was created by someone possessing the corresponding private key. This can be combined with a proof of identity system to know what entity (person or group) actually owns that private key, providing authentication.
Encryption with asymmetric cryptography works in a slightly different way from symmetric encryption. Someone with the public key is able to encrypt a message, providing confidentiality, and then only the person in possession of the private key is able to decrypt it.
