The English name of cryptography is Cryptography.

The English name of cryptography is Cryptography. Cryptography is a discipline that has been rapidly valued and developed in recent decades. Cryptography is often closely related to the four words information security. The earliest "ancestor" of cryptography can be said to have appeared as early as hundreds of years BC. Of course, there would not be such a complex security system as now.

However, in order to avoid the exposure of pure plaintext information, there will be a character mapping rule. One character of the message is replaced by another character. Only the sender and the receiver know this rule can they understand the true meaning of the message. . Until around the last century, with the rapid development of the computer information industry, cryptography gradually evolved into a proprietary discipline and developed. From the simplest one-way encryption to symmetric encryption algorithms, the discipline of cryptography It has become more and more like a hundred flowers blooming.

Common slogans in cryptography:

1. Key: divided into encryption key and decryption key

2. Plain text: no encryption, directly Information representing the meaning of the original text

3. Ciphertext: After plaintext encryption operation, the information represented by the original text is hidden

4. Encryption: The process of converting plaintext into ciphertext

5. Decryption: The process of converting ciphertext into plaintext

6. Cryptozoological algorithm: Algorithm operations used in encryption and decryption.
