Cross-language shell enhancement method and device, electronic equipment and storage medium

The invention discloses a cross-language shell enhancement method and device, electronic equipment and a storage medium. The method comprises the steps that a protection shell is added to an ELF format program needed by normal operation of a target application program, the target application program and the ELF format program are achieved based on different languages, a white-box password algorithm is stored in the protection shell, and a white-box password box is stored in the target application program; after the target application program is started, initializing the white box password box to obtain a key related variable, and transmitting the key related variable to the ELF format program; and the protection shell decrypts the encrypted data of the ELF format program according to the key related variable and the white-box cryptographic algorithm. According to the scheme, the data confidentiality of the protective shell can be effectively improved, and the ELF format program with the protective shell is ef
