In this embodiment, an information encryption method is provided, which may be used in the above-mentioned computer device, and fig. 2 is a flowchart of the information encryption method according to an embodiment of the present application, as shown in fig. 2, where the flowchart includes the following steps:

in step S201, in response to receiving the information to be encrypted and the digital parameter input from the outside, the encryption option sequence corresponding to the corresponding number of encryption types is selected from the key storage module based on the digital parameter, and the encryption option sequence is generated, where the key storage module stores a plurality of encryption option sequence numbers corresponding to different encryption types and corresponding to different encryption parameters, and the digital parameter represents the number of the selected encryption option sequence numbers. Please refer to step S101 in the embodiment shown in fig. 1 in detail, which is not described herein.

Step S202, the information to be encrypted is segmented one by one based on the key length corresponding to the encryption option sequence number in the encryption option sequence, and the encryption parameters comprise the key length corresponding to the encryption option sequence number.

Specifically, the step S202 includes:

in step S2021, the sum of the length of the information to be encrypted and the key length corresponding to all the encryption option serial numbers in the encryption option sequence is obtained.

In the embodiment of the present application, after receiving the information to be encrypted input from the outside, the length of the information to be encrypted may be obtained, and after selecting the corresponding number of encryption option numbers based on the above embodiment, the total of the key lengths corresponding to all the encryption option numbers may be calculated, for example, p=3, the key length corresponding to the 1 st encryption option number is 256 bits, the key length corresponding to the 2 nd encryption option number is 1024 bits, the key length corresponding to the 3 rd encryption option number is 256 bits, and the total length corresponding to the 3 encryption option numbers is 1536 bits, which is merely an example.

In step S2022, the size relationship between the length of the information to be encrypted and the sum of the key lengths corresponding to all the encryption option serial numbers in the encryption option sequence is determined.

In step S2023, if the length of the information to be encrypted is not greater than the sum of the key lengths corresponding to all the encryption option serial numbers in the encryption option sequence, the information to be encrypted is segmented sequentially according to the key length corresponding to the encryption option serial number in the encryption option sequence.

In step S2024, if the length of the information to be encrypted is greater than the sum of the key lengths corresponding to all the encryption option sequence numbers in the encryption option sequence, the key lengths corresponding to the encryption option sequence numbers in the encryption option sequence are circularly used to segment the information to be encrypted.

In step S2025, when the length of the last segment of the information to be encrypted is smaller than the key length of the corresponding encryption option sequence number, byte stuffing is performed on the information to be encrypted of the last segment until the length of the information to be encrypted of the last segment is consistent with the key length of the corresponding encryption option sequence number.

The embodiment of the application can judge the size relation between the length of the information to be encrypted and the sum of the key lengths corresponding to all the encryption option serial numbers in the encryption option sequence, for example, the length of the information to be encrypted is exactly equal to the sum of the key lengths, and the information to be encrypted can be segmented exactly according to the key lengths corresponding to the encryption option serial numbers in the encryption option sequence.

If the length of the information to be encrypted is smaller than the sum of the key lengths, the information to be encrypted can be segmented according to the key length corresponding to the encryption option serial number in the encryption option sequence, the length of the last segment of the information to be encrypted does not meet the key length requirement corresponding to the encryption option serial number, the last segment can be filled with bytes until the length of the last segment is just consistent with the key length of the corresponding encryption option serial number, for example, the length of the information to be encrypted is 1530, the information to be encrypted is segmented in sequence based on the 3 encryption option serial numbers, the length of the 1 st segment is 256, the length of the 2 nd segment is 1024, the 3 rd segment only remains 250 bits of the information to be encrypted at the moment, and the 3 rd segment can be filled with 6 bits of bytes, so that the information to be encrypted of the 3 rd segment is 256 bits.

If the length of the information to be encrypted is greater than the sum of the key lengths, the information to be encrypted can be segmented according to the key length corresponding to the encryption option serial number in the encryption option sequence, at this time, a part of the information to be encrypted is not segmented, the encryption option sequence can be circulated to segment the part which is not segmented again based on the key length corresponding to the encryption option serial number, if the length of the last segment of the information to be encrypted at this time does not meet the key length requirement corresponding to the corresponding encryption option serial number, the last segment can be filled with bytes until the length of the last segment is just consistent with the key length of the corresponding encryption option serial number until all the information to be encrypted is segmented.

According to the method, the size relation between the length of the information to be encrypted and the sum of the key lengths corresponding to all the encryption option serial numbers is judged, if the length of the information to be encrypted is larger than the sum of the key lengths corresponding to all the encryption option serial numbers in the encryption option sequence, the key lengths corresponding to the encryption option serial numbers in the encryption option sequence are adopted circularly to segment the information to be encrypted, when the length of the last segment of the information to be encrypted is smaller than the key length corresponding to the encryption option serial numbers, byte filling is carried out on the information to be encrypted of the last segment until the length of the information to be encrypted of the last segment is consistent with the key length corresponding to the encryption option serial numbers, and corresponding processing is carried out under any condition possibly occurring when the information to be encrypted is segmented, so that all the information to be encrypted can be encrypted in different encryption modes, and the privacy safety of the information is improved.

Step S2026 adds a byte pad identifier to the segmented information to be encrypted.

After the information to be encrypted is segmented based on the steps, the embodiment of the application can add byte stuffing identification to the information to be encrypted of each segment, for example, a 1 character is added to the information to be encrypted of the segment after byte stuffing, which indicates that the information to be encrypted of the segment is subjected to byte stuffing, a 0 character is added to the information to be encrypted of the segment without byte stuffing, which indicates that the information to be encrypted of the segment is not subjected to byte stuffing, and the embodiment of the application is only used as an example.

The application can intuitively extract the actual information of the current segment by adding the byte filling identification to the segmented information to be encrypted in the subsequent encryption or decryption.

Specifically, step S2026 includes:

and a step a1, adding a first identifier to the segmented information to be encrypted for byte stuffing, wherein the first identifier characterizes the corresponding byte stuffing number.

And a step a2, adding a second identifier to the segmented information to be encrypted which is not subjected to byte stuffing, wherein the second identifier indicates that the segmented information to be encrypted is not subjected to byte stuffing.

The embodiment of the application can add characters capable of representing the number of filled bytes to the segmented information to be encrypted for byte filling, for example, if the number of bytes of the segmented information to be encrypted is 2 bits, then '2' characters can be added to the segmented information to be encrypted, and only by way of example, character identifiers can also be added to the segmented information to be encrypted which is not filled to represent that the information to be segmented is not filled.

The application adds the corresponding identification of the byte filling number to the information to be encrypted which is filled with bytes, adds the identification which indicates that the information to be encrypted which is not filled with bytes, can distinguish whether the information to be encrypted is filled with bytes or not, and can rapidly extract the actual information to be decrypted when the information to be encrypted is encrypted and decrypted subsequently.

Step S203, the segmented information to be encrypted is sequentially encrypted based on the encryption option sequence numbers corresponding to the segmented information to be encrypted and the encryption parameters corresponding to the encryption option sequence numbers, and encrypted data is obtained.

Specifically, step S203 includes:

step S2031, encrypting the information to be encrypted of the current segment based on the encryption parameter corresponding to the encryption option sequence number corresponding to the information to be encrypted of the current segment.

Step S2032, forming a corresponding encrypted frame based on the encrypted information of the current segment and the encryption option sequence number and the byte pad identifier corresponding to the encrypted information of the current segment, where the encrypted frame at least includes the encryption option sequence number, the byte pad identifier and the encrypted information of the current segment.

Step S2033, splicing all the encrypted frames corresponding to the segmented information to be encrypted according to the encryption sequence, to obtain encrypted data.

The embodiment of the application encrypts the information to be encrypted of the current segment by utilizing other encryption parameters of the corresponding encryption calculation engine based on the encryption type, encryption key and the like in the encryption parameters corresponding to the encryption option serial numbers of the information to be encrypted of the current segment, adds the corresponding encryption option serial numbers and byte filling identifiers at the head of the information to be encrypted after encryption is completed to form an encryption frame corresponding to the information to be encrypted of the segment, and can splice all formed corresponding encryption frames according to the sequence of encryption after all segmented information to be encrypted form the encryption frame to form the encryption data corresponding to the information to be encrypted.
