Abstract

The invention applies to the technical field of the Internet and provides a login information encryption method and a terminal device. Feature codes of a device are obtained; the feature codes are rearranged according to a preset rule and then are converted into a feature character string; position supplement is carried out on the feature character string to generate a position supplemented character string; a feature group digest of each feature group is calculated in sequence according to positions of feature groups in the position supplemented character string; the feature group digest of the last feature group is taken as a device fingerprint; the device fingerprint is converted into an encryption key for encryption; and login information is encrypted through a preset encryption algorithm based on the encryption key obtained according to the device fingerprint, thereby generating a login ciphertext. Different devices are equipped with the encryption keys different from those of theother devices. Even if others obtain the encryption algorithm and the login ciphertext, the login ciphertext cannot be decrypted, and the login information of a user is well prevented from being stolen by the others.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a login information encryption method and terminal equipment. Background technique [0002] At present, people often need to enter login information when using the Internet. These login information generally include login names and passwords. When the login information entered by the user matches the data pre-stored in the server, the user can remotely use the authority corresponding to the login information. and data. In the prior art, for the convenience of login, users often choose the method of "automatic login next time". At this time, the user name and password will be encrypted as login information and stored in the local device. When the user needs to log in next time, only You can automatically log in by calling the login information stored locally. [0003] However, the current encryption key used to encrypt login information is hard-coded. You can se...
