Abstract
The invention is applicable to the mobile terminal technical field, and provides a document encrypting and decrypting method and an encrypting and decrypting device and a mobile terminal. The document encrypting method includes: a document is received and stored in a folder; and according to pre-set confidential information associated with the folder and the encryption algorithm, encryption is carried out to the received document. The embodiment of the invention conducts the encryption to the received document by receiving and storing the document in the folder, according to the pre-set confidential information associated with the folder and the encryption algorithm. The embodiment can conduct uniform encryption to documents requiring for encryption, and separate encryption of every document in the folder is not necessary; during decryption, once the decryption of the folder is successful, the decryption of the documents in the folder can be conducted, thereby saving time and greatly improving the efficiency of the mobile terminal.
Description
Technical field
The invention belongs to technical field of mobile terminals, relate in particular to a kind of file encryption, decryption method and encryption, decryption device and portable terminal.
Background technology
Exist different files in the existing portable terminal, different files is all arranged in each file, general, the user to be on the safe side, need carry out encryption to each file in the file, when the file in the file is operated, the clear crytpographic key of input this document, have only the clear crytpographic key of input correct, could operate accordingly this document.
But, when existing a large amount of files in the file of portable terminal, no matter be ciphering process to these files, still to all suitable loaded down with trivial details of the decrypting process of these files, this process of each file being carried out encryption and decryption, waste a large amount of time of user virtually, greatly reduced the work efficiency of portable terminal.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of file encrypting method, is intended to solve in the prior art, handles owing to need carry out encryption and decryption separately to each file in the file, influences the problem of work efficiency.
The embodiment of the invention is achieved in that a kind of file encrypting method, said method comprising the steps of:
Receive file and described file is saved in the file;
According to default confidential information that is associated with described file and cryptographic algorithm described file is encrypted.
Another purpose of the embodiment of the invention is to provide a kind of file decryption method, said method comprising the steps of:
Receive the confidential information that the user imports when opened file folder;
Judge whether described confidential information is identical with the default confidential information that is associated with described file, if then the file in the described file is decrypted.
The another purpose of the embodiment of the invention is to provide a kind of document encrypting apparatus, and described device comprises:
Document processing module is used to receive file and described file is saved in the file;
The file encryption module is used for according to default confidential information that is associated with described file and cryptographic algorithm described file being encrypted.
An also purpose of the embodiment of the invention is to provide a kind of file deciphering device, and described device comprises:
The confidential information receiver module is used to receive the confidential information that the user imports when opened file folder;
The confidential information judge module is used to judge whether described confidential information is identical with the default confidential information that is associated with described file;
The file decryption module is used for when the confidential information judge module judges that described confidential information is identical with the confidential information of presetting that is associated with described file the file in the described file being decrypted.
An also purpose of the embodiment of the invention is to provide a kind of portable terminal, and described portable terminal includes the document encrypting apparatus that the embodiment of the invention provides.
An also purpose of the embodiment of the invention is to provide a kind of portable terminal, and described portable terminal includes the file deciphering device that the embodiment of the invention provides.
The embodiment of the invention is by receiving file and described file being saved in the file, according to the default confidential information and the cryptographic algorithm that are associated with this document folder the file that receives is encrypted, thereby can unify to encrypt to the file that needs are encrypted, needn't encrypt separately each file in the file, when deciphering, as long as successful declassified document folder just can be decrypted the file in this document folder, thereby save time, greatly improve the operating efficiency of portable terminal.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 shows the flow process of the file encrypting method that the embodiment of the invention provides, and details are as follows.
In step S101, opened file folder.
Concrete, when opened file folder, the user can import the confidential information of this document folder and open this document folder, but no matter whether this confidential information is correct, can both open this document folder; Perhaps, the user can directly open this document folder.But, if the confidential information mistake, perhaps the reader confidential information is not directly opened this document folder, then can not edit the file in the file.
In step S102, receive file and described file is saved in the file.
In step S103, the file that receives is encrypted according to the default confidential information and the cryptographic algorithm that are associated with this document folder.
As embodiments of the invention, this confidential information is password or fingerprint.
Fig. 2 shows the flow process of the file decryption method that the embodiment of the invention provides, and details are as follows.
In step S201, receive the confidential information that the user imports when opened file folder.
In step S202, judge whether the confidential information that receives is identical with the default confidential information that is associated with file, if then execution in step S203 presss from both sides otherwise still can open this document, but can not edit the file in the file.
As embodiments of the invention, this confidential information is password or fingerprint.
In step S203, the file in this document folder is decrypted.
See also Fig. 3, the embodiment of the invention also provides a kind of portable terminal, and this portable terminal comprises a document encrypting apparatus, and this document encryption device comprises document processing module 31 and file encryption module 32.
Wherein, document processing module 31 is used to receive file and described file is saved in the file.
