Dynamic Flash partition real-time encryption method and device and storage medium

The invention relates to the technical field of encryption, and provides a dynamic Flash partition real-time encryption method, which comprises the following steps of: firstly, carrying out de-protection on a Flash partition in a protection state of first electronic equipment through second electronic equipment, then judging whether the first electronic equipment supports re-encryption or not in a de-protection state, and if yes, carrying out re-encryption on the Flash partition. According to the embodiment of the invention, after the first electronic equipment is judged to support re-encryption, the configurable encryption interface is skipped to allow the user to input the starting address and the ending address of the Flash partition needing to be encrypted, so that real-time dynamic adjustment of the Flash encryption partition is realized, and the technical problem that the protected partition is fixed and cannot be adjusted in the prior art is solved. Besides, the encryption mechanism adopted by the inve
