How often do you communicate with your friends, family and co-workers? A lot. Probably much more than you think. In addition to in-person communication, you also communicate through phone, messages, emails and other technological services. Have you ever wondered how secure your communication is? Everyone wants to be assured that their communication is secured from strangers. That is why Information security becomes important. It is a very wide term and it covers all aspects of securing different types of information.

Cryptography is a part of information security and plays an important role in protecting our information from strangers. It keeps our data and communications secure by encryption and decryption. You might be interested to know that cryptography is used for secured emailing and text messaging. It is simple process. Basically, with the help of secured password or pin number, the sender encrypts the message by sending it and only recipients can decrypt the message by reading it. This makes your communication more secure. The concept of cryptography is even used in online transactions to keep your identity and bank account secured. For example, when you purchase something online from any corporation, you give permission to share your identity and bank data entrusted to a secure encryption system of any given corporation. This system protects you from security threats.

Cryptography has definitely helped many people in securing their information, but still I cannot say that our information is fully protected. In the past, there have been many cases where hackers had cracked in the system and stole personal information. However, I am very sure that cryptography will be able to fully secure our information with the help of new technologies in the near future.
