Protecting information by transforming it (or encrypting it) into an unreadable format is called cyphertext. Only users who possess a secret key can decipher (or decrypt) the message into plain, readable text. Encrypted messages can sometimes be deciphered by cryptanalysis (code breaking), although modern cryptography techniques are virtually
unbreakable. As the Internet and other forms of electronic communication become more popular, electronic security is becoming increasingly important. Cryptography is used to protect e-mail messages, credit card information, and corporate data. Cryptography systems can be broadly classified into symmetric-key systems that use a single key that both the sender and recipient have, and public-key systems that use two keys, a public key known to everyone and a private key that only the recipient of messages uses.
