	Asymmetric encryption is widely used around the world. It uses Internet standards such as Transport Layer Security, in which segments are encrypted at the Application Layer to secure end-to-end transit at the Transport Layer. PGP and GPC are also utilized, both of which are alternative suites of encryption, often used for signing, encrypting and decrypting email messages.

	Throughout the history of mankind, spanning over thousands of years, society has found it important and necessary to keep certain information private. Cryptography became the study and practice associated with hiding such information. In this paper, I will describe how encryption and cryptography have evolved with time, and explain the methods that are most commonly used for data protection in today’s technological society. This page is intended to supply summaries on the key points of history and current methods, using fairly simple explanations from several websites. By researching to find terminology and concepts that can be easily understood by students without extensive knowledge in the computer field, the collected summaries on this page provide shortcuts to extended information previously researched by outside sources.

			As with symmetric encryption, there are also weaknesses in asymmetric encryption. These weaknesses may include:


			* Brute force key search attack, in which a search of all the possible solutions is tried until the correct key is found. Creating a longer key can help decrease the chances of the key being discovered becuase it adds many additional combinates for the attack to work through, increasing the time it would take to crack the encryption, making it less favorable to be attempted.

			* Side channel attack, in which information is obtained from physical execution or planning of a crytosystem. These types of attacks can be a result of exposed timing information, power consumption, or sound.

	In asymmetric-key encryption, the message does not require a secure initial exchange of secret keys between sender and receiver. This method is also known as public-key cryptography. A mathematically related pair of keys, a secret private key and a published public key are created using these algorithms. A digital signature is created by using these keys to verify the authenticity of the message. The private key is kept secret and the public key is passed out with less constraints. the recipient's key encrypts the message and the corresponding private key is the only way the message can be decrypted. Once the key is used, the message is verified. A message that is encrypted using a public key can only be decrypted using the private key.
