Asymmetric Encryption

Asymmetric encryption is also known as public key cryptography which is a relatively new area compared to symmetric encryption. Asymmetric encryption uses two keys to encrypt your plain text. This came to the arena to address an inherent problem with the symmetric cipher. If the eavesdropper somehow get hold of the symmetric secret key, then the whole point of encryption is nullified. This is highly probable because secret key may have to be communicated over unsecure communication channels. As a solution, asymmetric encryption uses two key where one key is publicly available, and the other key is private and is known only to you.
