When detecting the reading command of Wi-Fi password, obtain described Wi-Fi password to be read;
Operation is decrypted to described Wi-Fi password to be read, using the Wi-Fi password after deciphering as the Wi-Fi password read.
Should be noted that, when user connects history AP by mobile terminal, the Wi-Fi module of mobile terminal will generate the reading command of the Wi-Fi password of corresponding described history AP, to read the Wi-Fi password of corresponding described history AP from wpa_supplicant.conf file, complete Wi-Fi and connect certification.In the present embodiment, when detecting the reading command of Wi-Fi password, obtain described Wi-Fi password to be read.
It will be appreciated by persons skilled in the art that in the present embodiment, the Wi-Fi password of corresponding different AP stores with the form of ciphertext.After getting described Wi-Fi password to be read, need to be decrypted operation to described Wi-Fi password to be read, and the Wi-Fi password after deciphering being back to the Wi-Fi module of mobile terminal as the Wi-Fi password read, the Wi-Fi module for mobile terminal completes Wi-Fi and connects certification.
Such as, when needs are deciphered, call the API of mobile terminal this locality wpa_config_parse_psk () by name, corresponding decryption oprerations is carried out to described Wi-Fi password to be read.
Further, in the first embodiment of Wi-Fi password storage means of the present invention, described the step of operation is decrypted to described Wi-Fi password to be read after, described Wi-Fi password storage means also comprises:
When to described Wi-Fi password to decipher failure to be read, display reminding information, is confirmed whether to re-enter Wi-Fi password based on described information display interface for user;
When receiving the confirmation that user inputs based on described information display interface, display interface for password input inputs Wi-Fi password for user;
When receiving the Wi-Fi password of user's input, operation is encrypted to described Wi-Fi password;
Wi-Fi password after encryption is stored to the storage area that default store path points to.
It will be appreciated by persons skilled in the art that in the operational process of mobile terminal to there is many factors and cause deciphering unsuccessfully, such as, when deciphering, internal memory overflows and will cause deciphering unsuccessfully.In the present embodiment, when to described Wi-Fi password to decipher failure to be read, the Wi-Fi module of mobile terminal can not read the Wi-Fi password being used for Wi-Fi and having connected certification, and then cause authentification failure.Now need user to re-enter corresponding Wi-Fi password: by the screen display information of mobile terminal, be confirmed whether to re-enter Wi-Fi password based on described information display interface for user; When receiving the confirmation that user inputs based on described information display interface, display interface for password input inputs Wi-Fi password for user; When receiving the Wi-Fi password of user's input, the Wi-Fi password received being forwarded to the Wi-Fi module of mobile terminal, completing Wi-Fi for it and connecting certification; Operation is encrypted to described Wi-Fi password simultaneously; And the Wi-Fi password after encryption is stored to the storage area of default store path sensing.
Further, based on the first embodiment, propose the second embodiment of Wi-Fi password storage means of the present invention, in the present embodiment, above-mentioned steps S10 comprises:
When the storage instruction detecting Wi-Fi password, obtain the operational mode that mobile terminal is current;
When running of mobile terminal is at encryption mode, operation is encrypted to described Wi-Fi password to be stored.
In the present embodiment, conveniently user uses, can decide whether open encryption mode (encryption mode and preceding solution) in its sole discretion by user, when user needs to open encryption mode, the specific interface that can be provided by mobile terminal is selected to open encryption mode.Particularly, when the storage instruction detecting Wi-Fi password, obtain the operational mode that mobile terminal is current; When running of mobile terminal is at encryption mode, operation is encrypted to described Wi-Fi password to be stored.The embodiment of the present invention is selected for user by providing optional encryption mode, can improve Consumer's Experience.
In order to the security of Wi-Fi password can be promoted further, based on the first embodiment or the second embodiment, propose the 3rd embodiment of Wi-Fi password storage means of the present invention, in the present embodiment, in above-mentioned steps S10, operation be encrypted to described Wi-Fi password to be stored and comprise:
Obtain the identification code of mobile terminal;
Based on described identification code, operation is encrypted to described Wi-Fi password to be stored.
It should be noted that the difference of the present embodiment and above-described embodiment is, in the present embodiment, obtain the identification code of mobile terminal, and based on described identification code, Hybrid Encryption process is carried out to described Wi-Fi password to be stored.Described identification code comprise mobile terminal insert ICCID (the Integrate circuit card identity that SIM (Subscriber Identity Module client identification module) blocks, integrated circuit card identification code), at least one in the IMEI (International Mobile EquipmentIdentity, the international identification code of mobile device) of cell-phone number corresponding to described SIM card and mobile terminal.
Such as, get the IMEI of mobile terminal for " AAAAAA ", get described Wi-Fi password to be stored for " BBBBB ", " ABABABABABA " will be obtained after its hybrid processing, adopt corresponding cryptographic algorithm to be encrypted operation to " ABABABABABA " that obtain after mixing.
It will be appreciated by persons skilled in the art that corresponding, when being decrypted operation to described Wi-Fi password to be read, needing the identification code of acquisition mobile terminal and based on described identification code, operation being decrypted to described Wi-Fi password to be read.
The present invention further provides a kind of Wi-Fi password storage device, with reference to Fig. 4, in the first embodiment of Wi-Fi password storage device of the present invention, described Wi-Fi password storage device comprises:
