Because the ancient Chinese language, like its modern day equivalents, was composed of a set of symbols that represented varying syllables, tones, and ideas,<ref name="ancientchinese">[http://www.donet.com/~rcooper/museum/search/misc/aclsc.htm Ancient Chinese Language Supports Creation]</ref> it readily lent itself to a language of the cryptographic arts. Messages would be altered based on content, tone, and similarity between symbols to messages unrecognizable to other factions at the time or people without advanced knowledge of the language.<ref name="shorthistory" />

In 1553, Giovan Batista Belaso extended Trithemius' technique by restarting the keyword after every individual letter in the original message. This varied the size of the text between the length of each text, so without prior knowledge of the beginning text, decryption by the means available at the time became virtually impossible.

The event that thrust cryptography into the modern age, however, and caused governments and armies around the world to take notice occurred in 1628, with the Frenchman Antoine Rossignol's defeat of a Hugenot army by decoding a captured message that detailed their coming deployment plans. Soon after his victory, the French government began asking him to solve numerous ciphers, and other nations and city-states began forming dedicated organizations to break ciphers and protect information.<ref name="briefhistory" />

Today, the science of cryptography is divided between public key and private key cryptosystems. Although mathematically, these are two distinct systems of encryption, they are often combined into a system referred to as a '''[[hybrid key cryptosystem]]''', where different parts of a code rely on either public or private keys. The most commonly used hybrid key cryptosystem today is used throughout the Internet, and is a combination of the public key [[RSA]] system and the private key [[AES]] system.

The rise of modern cryptography has furthered the progress and development of the Internet, as powerful encryption algorithms have made possible the transmission of sensitive data, eg. credit card numbers, phone numbers, social security numbers, with minimal fear of useful interception, theft, and other malicious actions. Virtually all Internet sites that deal with financial information, e.g. banks, credit card companies, etc, as well as sites that deal with general personal information like email, use encryption in the ''https'' prefix on their web URL.<ref name="https">[http://searchsoftwarequality.techtarget.com/sDefinition/0,,sid92_gci214006,00.html What is HTTPS?]</ref> This encrypts and protects information transmitted through that web page.
