Abstract

The invention discloses a password storage method and a device, and a password verification method and device. The password storage method comprises the following steps: acquiring a password and saltto be added into the password; performing data processing on the password to obtain processed data; encrypting the salt by adopting the processing data to obtain encrypted salt; encrypting the processed data by adopting salt to obtain a password stub of the password; and storing the encryption salt and the password stub. According to the method and the device, the technical problems of relativelylow password processing reliability and relatively high risk in related technologies are solved.

Description

Technical field [0001] The present invention relates to the technical field of computer information security, in particular to a password storage method and device, and a password verification method and device.
