Embodiment 1 of the present invention provides a browser data encryption method, which is specifically shown in fig. 1 and includes the following steps:
and step 110, performing hash calculation on the preset browser PIN code to generate a hash value. The hash calculation may transform an input of arbitrary length into an output of fixed length by a hash algorithm.
Optionally, before performing the step, the method further includes: and setting a PIN code of the browser. When a user uses a browser for the first time, a Personal Identification Number (PIN) of the browser needs to be set on user terminal equipment, namely a Personal digital screen locking password of the browser, the PIN of the browser is only known by the user and is only stored locally and cannot be stored in a remote server, and the PIN of the browser is associated with the user terminal, so that the cached data adopting the encryption method can be decrypted only at the user terminal, and the data can not be decrypted when being stolen and copied to other terminals.
After the browser PIN code is preset, the method further comprises the following steps: and the user enters a browser home page by inputting a preset browser PIN code on a browser screen locking interface. When the user uses the browser next time, the user can use the browser only by inputting a preset PIN code into a screen locking interface of the browser for unlocking, otherwise, the user cannot enter a main page of the browser. The browser data includes information such as cache, cookie, and user password that is automatically saved.
In step 110, specifically, the browser PIN code is calculated by using the SHA256HASH algorithm to obtain a HASH value of 32 bytes, and the HASH value is stored in the HASH list. The user may generate a plurality of PIN codes, each time a new PIN code is generated, it is stored in the HASH list. Corresponding to the HASH value, an integer type variable I records the position index of the PIN code in the HASH list.
And step 120, encrypting the browser data generated in the process of accessing the browser by the user by using the hash value as an encryption key and adopting a preset encryption algorithm.
Specifically, a user accesses browser data such as a cache, a cookie and a user password generated by a browser, uses a hash value of a latest PIN code of the user as an encryption key, calls a windows own encryption algorithm tool CrytProtectData to encrypt the browser data, and stores the encrypted browser data in a local disk or a memory.
And step 130, writing the encrypted browser data into a local disk or a memory for storage.
When the browser data is used, the encrypted browser data and a corresponding encryption key are obtained, and the encryption key is used for calling a windows own decryption algorithm tool CryptUnProtectData to decrypt the encrypted browser data to obtain the browser data.
The browser data are encrypted and stored after being encrypted through the process, the hash value of the PIN code of the browser is used as the encryption key, the data cannot be decrypted even on a user terminal without the PIN code set by a user, the PIN code does not store a remote server, the safety problem caused by network data transmission is avoided, the data are higher in safety and stronger in confidentiality, all encryption levels are associated with the experience and tolerance of the user, if the user loses the PIN code, the stored data before can not be decrypted, and the program can discard the data.
