Fig. 1 shows the realization flow of a kind of encryption method that the embodiment of the present invention provides, and executive agent is for encrypting client, and details are as follows:
In step S101, set up character match storehouse, the first character and the second character that described character match storehouse comprises the unique coupling of many groups.
In embodiments of the present invention, encrypting client and deciphering client and set up identical character match storehouse, wherein comprise the first character and second characters of the unique coupling of many groups, character can be word, punctuation mark or its combination etc., and relevant semantically.The first character can be one to one or the mapping relations of one-to-many to the second character.As, the first character " is opened " corresponding with the second character " Zhang "; The first character "! " corresponding with the second character " O (∩ _ ∩) O " and " (^o^)/" etc.
In step S102, obtain the first text message and the second text message.
In embodiments of the present invention, obtain the first text message and second text message of user's input, urtext when the first text message is proper communication, the second text message is some sensitive informations, during communication, encrypt client the second Text information hiding is sent in the first text message, the take over party who has corresponding deciphering client could restore the second text message.
In step S103, according to described the second text message, determine character position, described the first character with respective symbols position in the first text message described in described the second character replacement, form the 3rd text message, so that described deciphering client restores described the second text message from described the 3rd text message.
In embodiments of the present invention, the character position definite according to the second text message, selectively with the first character in second character replacement the first text message, for example, in the first text message, there are a plurality of " opening ", the definite character position of the second text message is 5, and ciphering process replaces with " Zhang " by the 5th " opening " wherein, and remaining does not process.
As one embodiment of the present of invention, according to the character position that the second text message is definite, replace, as shown in Figure 2, S103 detailed process is as follows:
In S201, described the second text message is converted to numerical information.
The second text message is converted to numerical information, and as shown in Figure 3, S201 detailed process is as follows:
In S301, described the second text message is converted to binary sequence.

In step S403, in described the 3rd text message, search the first character and the second character, and the first character finding and the second character are counted.
In embodiments of the present invention, corresponding with ciphering process, since the first character of the 3rd text message, search the first character and the second character that belong in character match storehouse, often find first character or the second character, counter adds 1; For neither the first character neither the second character, counter is left intact.When finding the second character, the value of counter has represented the character position of the second character in the first character finding and the second character, and this character position has been the character position of the second text message of having encrypted interval scale.
In step S404, according to count value corresponding to the second character finding, generate described the second text message.
As one embodiment of the present of invention, according to count value, reduce the second text message, as shown in Figure 5, S404 idiographic flow is as follows:
In S501, count value corresponding to each the second character finding is converted to binary sequence section.
In embodiments of the present invention, when finding the second character, the value of counter is converted to binary sequence section.Counter O reset after each conversion continues to search from this character position by above-mentioned steps backward, and counter restarts counting, and the above step that circulates until searched the second all characters in the 3rd text message.
In S502, splice described binary sequence section and obtain binary sequence.
A plurality of binary sequence sections that splicing obtains, form a binary sequence.The configuration parameter that deciphering customer end adopted is corresponding with encrypting client if the length of binary sequence section is less than the length of cutting apart while encrypting, splices after the leading zero of binary sequence section again.
In S503, described binary sequence is converted to the second text message.
When the binary sequence being obtained by above step is encryption, by the converted binary sequence of the second text message, binary sequence is converted to text and can restores the second text message.
For non-deciphering client, only show the 3rd text message, and the 3rd text message is semantically identical with the first text message, does not affect normal reading.
