What is a network password?

Network password is a very confusing technology, and users want to turn normal (identifiable) information into unrecognizable information. But this unrecognizable information part can be reprocessed, recovered and cracked. Password is a general term for "password" in Chinese.

Password is a symbol compiled according to a specific law, which is used to transmit the information of both parties.

In other words, a password is a series of symbols that hide the real content. It changes the information expressed by an open and standard information code into an information code that can't be read by anyone except the two communication parties through a transformation method. This unique information code is a password.

Encryption method

1, RSA algorithm

RSA algorithm is the first algorithm that can be used for both encryption and digital signature, and it is also easy to understand and operate. RSA algorithm is an asymmetric encryption algorithm. The so-called asymmetry means that the algorithm needs a pair of keys. If one is used for encryption and the other is used for decryption.

2.ECC encryption method

ECC algorithm is also an algorithm that can be used for encryption and digital signature at the same time, and it is also easy to understand and operate. Like RSA algorithm, asymmetric cryptographic algorithm uses one encryption and the other decryption.

3. Four-fold password

The tetragonal cipher is encrypted with four 5×5 matrices. Each matrix has 25 letters (usually Q will be cancelled or I and J will be regarded as the same, or a 6×6 matrix will be improved and 10 numbers will be added).

First, choose two English words as keywords, such as example and keyword. For each key, the repeated letters will be removed, that is, the EXAMPLE will be converted into the example, and then each letter order will be put into the matrix, and then the remaining letter order will be put into the matrix to get the encryption matrix.
