The set passwords are all digit passwords, and the maximum length is no more than 16 digits. The reading module 21 is configured to read the byte code constituting the file, and use ten byte codes as one line, so that each line corresponds to one digit password. Specifically, files stored inside the computer are composed of a combination of bytes (Byk). As shown in FIG. 4, it is a byte code of a file. As can be seen from the figure, when the reading module 21 reads the byte code of the file, ten lines are - and each line Each byte has a position, an apostrophe, and the number from the number 9 to 9 'assuming that the password set by the user is 6 $ 〇28, ^仃, corresponding to a number of digits exhausted, for example, the first line The digits of the byte are exhausted to 6, the digit of the byte of the second row is 5, and the digit of the byte of the third row is 〇, and the fourth is the number of stitches of the horse. The byte code corresponding to the byte is 8 and then every 6 lines is filled with the corresponding digit password, that is, the bit 6 of the seventh line is in accordance with this loop, until the end of the byte code. (4) Also for the search module 22, it is used to find the location of each of the corresponding lines of 201013453. Specifically, as shown in FIG. 4, the digit password corresponding to the row in the first row of bits is 6, and the location of the digit password is the location of 6 'if the third behavior example' corresponds to the digit of the row. 7 The location of the digit password is the location marked 0. The cryptographic module 23 is configured to insert two randomly generated bit elements at the position of each row of the byte of the byte to encrypt. The inserted byte group may have two or more bit stations of two bytes, and the more the bit bytes inserted, the more the degree of encryption / the number of bytes inserted in the preferred embodiment is two One. The interpolated binary code is generated by a random function (Random). Specifically: in the first-after-test code riding, the domain-made moire position is 6, then insert two pure elements after the (10) position of the line, as shown in Figure 5, for the first line in Figure 4. The byte code is encrypted =, from the figure it can be seen that 'insert two randomly generated byte codes among the two randomly generated octet codes. Saki contains the position element (4). (After the encryption of the byte code for each line in Figure 4, the image is decoded after the image is encrypted. The generation module 24 is used to combine the encrypted byte codes together' An encrypted slot file is generated. The encrypted file needs to be input with a password to be read. As shown in FIG. 2, a flow chart of a preferred embodiment of the method for encrypting a slot in a handheld mobile electronic device is shown. Step si〇, the setting module 20 sets the encryption of the rights (four) 'The set of Misaki is a digital password. The file may be a file (eg, sneak), picture and video resources 201013453. The setting The passwords are all digitally secret, and the longest is not more than (four) digits. Step sn, the reading module 21 reads the byte code that constitutes the broadcast, and uses ten digits as the line, so that each The row corresponds to a digit password. Specifically =, = the internal storage slot is composed of bytes (_ combination 2 into ^ Figure 4, is a byte of the file, as can be seen from the figure, read Module 2! When reading the byte of the slot, the group code is -row, and each row is The digit = lamp corresponds to a digit password, for example, the bit mil is 6, the second row of the byte corresponds to the number ^ to f rows, the tuple corresponds to the digit password is 0, the fourth _, ^ ^ 5 , the second code is 2 'the fifth line of the byte code corresponding to the number of bits is Π巧 ", the 7L group drink the corresponding number of 密马 is 8, then every six, six, then fill in the corresponding number 1乍 is a loop, according to this loop, the straight byte is also 6, according to the digit ==, 22 finds the position of each row-valued tuple 应 position. Specifically and " 'As shown in Figure 4, the first: in the position is the number 6 position, if the third, the number: exhausted as the 〇, then the location of the digital password is 禆: the line of correspondence - step 叱, encryption module 23 is in the position of 0 in each row. The digits of the digits, the digits of the digits, and the corresponding digits are encrypted. The randomly generated byte groups, so that the byte code inserted for each line of attack can be two. One bit level, also 9 201013453 is more than two bytes, the more the inserted bytes, the more "high" the encryption is in the preferred embodiment, the insertion The number of byte groups is two. The inserted byte code is generated by a random function (Random). Specifically, taking the first row of the byte code in FIG. 4 as an example, the corresponding digital password of the row is 6, where the position is 6', then insert two byte codes after the sixth position of the line, as shown in Figure 5, the process of encrypting the first line of the byte code in Figure 4, from the figure It can be seen that after inserting two randomly generated byte groups 蠡 (two underlined byte codes in Figure 5), the line contains 12 byte codes. For each row in Figure 4 After the group code is encrypted, Figure 6 is a schematic diagram after encryption. In step S14, the generation module 24 combines the encrypted byte codes to generate an encrypted file. The encrypted file needs to be input with a password to be read. As shown in FIG. 3, it is a flowchart of a preferred embodiment of the method for performing file archiving in a handheld mobile electronic device. ❹ First, in step S2, the byte code of the encrypted file is read in a row of twelve byte codes. The file may be an archive (e.g., Word material), a picture, and a video material. In step B21, the password set by the user is input. The set passwords are all numeric passwords and can be up to 16 digits in length. In step S22, it is found that the digit password corresponding to each row of the byte code is at the position of the line. Specifically, as shown in FIG. 6 , taking the first row of the byte code as an example, if the digital password corresponding to the 5th row is 6, the position of the digital password is 疋 'the position of 6, if the third behavior For example, if the corresponding digit of the line is 201013453, the location of the digit password is the position marked 〇. Step S23' removes the two byte codes following the position of the digit password in each line, and decrypts the slot. Specifically, taking the first row of the byte code in FIG. 6 as an example, the corresponding digit password of the row is 6, and after the location 6, the two byte codes corresponding to the positions 7 and 8 are taken out, and the _ row bit is taken. The group code is restored to the previous bit (four), and the (four) action is completed. In step S24, the decrypted byte code is combined to be the original byte code of the file. If the password entered by the user is incorrect, then the correct decryption of the decrypted 'decrypted slot case is not the original slot case. It should be understood that the above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to be construed as the invention. The technical solutions are modified or equivalently substituted without departing from the spirit and scope of the technical solutions of the present invention.
