Composition of password
Password is a symbol coded according to a specific law, which is used to secretly convert the information of both parties. In other words, a password is a series of symbols that hide the real content. It converts the information represented by public information codes and standard information codes into information codes that can't be read by others except the communication party through a conversion means. This unique information code is the password.
Cryptography is a science with a long history. In the war between ancient Greece and the Persian Empire, passwords were used to transmit secret information. In modern wars, the transmission of information and the command of war are inseparable from passwords, and so is the diplomatic struggle. Passwords are generally used for the confidentiality of information communication transmission and storage.
With the development of computer and information technology, the development of cryptography is also very rapid, and its application field is also expanding. In addition to information encryption, passwords are also used for data information signature and security authentication. In this way, the application of cryptography is not limited to military and diplomatic struggles, but also widely used in social and economic activities.
Nowadays, there has been a trend of socialization and personalization of password application in the world. For example, cryptography can be applied to e-commerce to identify the identities and commercial credits of both parties in online transactions and prevent "hackers" and fraud in online e-commerce.
