Abstract
The present disclosure provides a method for encryption programming, including: selecting an encrypted programming file that matches the programmer from a target folder; loading the selected encrypted programming file; if a current number of times for programming of the programmer is greater than or equal to a maximum number of times for programming, destroying the selected encrypted programming file and ending programming; otherwise, decrypting the selected encrypted programming file; if the current number of times for programming of the programmer is less than an initial number of times for programming, replacing the current number of times for programming of the programmer with the initial number of times for programming, otherwise, re-encrypting the decrypted encrypted programming file and programing the re-encrypted programming file into a target chip. A programmer is further provided.
