Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
The first embodiment is as follows:
as shown in fig. 1, the present embodiment provides an electronic device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor, and when the processor executes the program, the method for encrypting content information as described below is implemented, and specifically includes the following sub-steps:
s101: receiving content information and a first authorization key sent by a first terminal, wherein the content information is text information or picture information or a combination of the text information and the picture information; the setting of the credit granting secret key is flexible, and the credit granting code with any length can be set according to the protection level;
s102: and encrypting the received content information to obtain encrypted data, and returning the encrypted data to the first terminal. The above steps are mainly used for encrypting specific data, and the following conditions are mainly adopted in the encryption process: 1. the content information to be encrypted is literal content information; 2. the content to be encrypted is picture content information; 3. the content to be encrypted is a mixture of text content information and picture content information.
When encrypting the first case, usually a numeric string is obtained, which has corresponding start and end characters, and when designing, the start and end characters are designed as the same number, and the number does not appear in the intermediate content information, such as: the initial character and the terminal character of the numeric character string are both 1, and the numeric characters between the initial character and the terminal character are other characters except 1.
When the second case is encrypted, picture encrypted data is obtained in general, and the picture encrypted data is generally composed of different color blocks, and most preferably, blank areas are arranged on the left side and the right side of the picture encrypted data. The purpose of setting the blank area is to make the areas on both sides look different from the ordinary picture, so that the user who knows the encryption mode can conveniently know whether the picture is the real picture or the encrypted data.
When encryption is performed for the third case, the result is a combination of the first and second cases. So that the encryption method of the embodiment can be more generally applicable.
In the method for encrypting the content, the encrypted ciphertext consists of 0-9 digits, so that mixed transmission of the plaintext and the ciphertext can be realized, usually, the encrypted data cannot be directly read, a corresponding secret key must be input to be decrypted, or a string of scrambled data cannot be obtained, under the condition that the encrypted data is transmitted through the encrypted data, the encrypted data is easily known by the outside, and the encrypted data cannot be distinguished by the outside usually by converting the encrypted data into a digital character string, so that the security of the data is ensured to a certain extent; in addition, the method for encrypting content in this embodiment introduces a time variable, so that the obtained encrypted data may also be different with time change, for example, a data string obtained when "hello" is encrypted for the first time is "10256305575257632257633246325542001", but a string obtained when data is encrypted for the second time is: 102563055752576322576369875345565455781, which obtains different character strings to make the password more difficult to decode, further ensuring the data security.
The working principle of the embodiment is as follows:
in this embodiment, in the process of chatting over WeChat, when a user needs to encrypt corresponding content, the user needs to select the content information first and place the content information in software storing the method of this embodiment, so that an encrypted picture and a string of encrypted characters can be obtained. Such as: "you are just! Communication protection system! "characters and pictures
The following is the result after the treatment.
155032755622755092755897558092755892475589975586207558420755822375589227558927558622755839755842975589375583227558622755862075582247558696755859755822275583975589237558620755842071
The part of the content can be transmitted to another user, so that the encryption of information is completed, the encrypted data can effectively prevent illegal monitoring and protect the communication content. In the method for encrypting the content information of the embodiment, the form of encryption is not added, but a ciphertext and plaintext conversion mode is adopted, and in this case, the encryption stage is not passed in the process of communicating information, so that the information is not easily identified by a listener. When information is transmitted, encrypted data and contents to be transmitted can be mixed, so that the whole information transmission process has a local encryption function.
Example two
The second embodiment discloses a readable computer storage medium, which is used for storing a program, and when the program is executed by a processor, the method for encrypting the content information of the first embodiment is realized.
Example three:
as shown in fig. 2, the present embodiment provides an electronic device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor, and when the processor executes the program, the method for decrypting content information as described below is implemented, and specifically includes the following sub-steps:
s201: receiving encrypted information data and a credit authorization key sent by a second terminal, wherein the encrypted information data comprises encrypted data, and the encrypted data is digital encrypted data and picture encrypted data; a second terminal which, when receiving the encrypted information, is likely to be a string of character strings or picture encrypted data, or is also likely to be a combination of information content and character strings;
s202: judging whether the second trust key is consistent with the first trust key or not, and if so, executing a decryption step; the method mainly aims to prevent the password from being decoded by other users except software, so that the content can be transmitted and decoded only in a specific crowd;
s203: and decrypting the received encrypted information data to obtain corresponding content information, and returning the content information to the second terminal.
The working principle of the embodiment is as follows:
when receiving the encrypted data provided by the content according to embodiment one, and the first trust key and the second trust key are the same, the combination of the character string and the picture can be directly added to translate into "good you! Communication protection system!
". The decryption method of the present embodiment may interpret the combination of the content information and the encrypted data, such as when "hello 102562256365332555236443263231" is received, it may automatically identify whether it is the content information or the encrypted data, decrypt it memorialically when the identified encrypted data is identified, and do not operate on it when the textual content information is identified.
The first terminal described in the first embodiment and the second terminal described in the third embodiment may be the same device, for example, when the user encrypts the data content in the word file on his or her own computer, he or she saves the word content on the computer, so as to prevent someone from stealing the data, and when he or she needs to read the content, he or she can directly decrypt and read the encrypted data.
Example four
The fourth embodiment discloses a readable computer storage medium, which is used for storing a program, and when the program is executed by a processor, the method for decrypting content information of the third embodiment is realized.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
