Encryption is the process of transforming information in such a way that an unauthorized third party cannot read it; a trusted person can decrypt data and access it in its original form though. There are a lot of popular encryption/decryption methods, but the key to security is not a proprietary algorithm.
Asymmetric Encryption. Asymmetric encryption (or public-key cryptography) uses a separate key for encryption and decryption. Anyone can use the encryption key (public key) to encrypt a message. However, decryption keys (private keys) are secret. This way only the intended receiver can decrypt the message.
