[Share] convert global strings to local variable storage to prevent sensitive strings from being exposed by static analysis.

Global String Conversion to local variable storage prevents software from being exposed to sensitive strings by static analysis, supports UNICODE character sets and multi-byte character sets, supports Chinese characters, and does not perform encryption.

Running effect:

 

Enter the global string to be converted, for example, C: \ file \ my file. txt. Output:

// C: \ file \ My file .txt # ifdef _ UNICODETCHAR szC: \ file \ My file .txt [] = {'C ',':','\\', 'F', 'I', 'l', 'E', '\', 0x6211, 0x7684, 0x6587, 0x4EF6 ,'. ', 't', 'x', 't',' \ 0'}; # elseCHAR szC: \ file \ My file .txt [] = {'C ',': ',' \ ', 'F',' I ', 'l', 'E',' \ ', 0xCE, 0xD2, 0xB5, 0xC4, 0xCE, 0xC4, 0xBC, 0xFE ,'. ', 't', 'x', 't',' \ 0'}; # endif

If the string does not contain Chinese characters, for example, file not found

//file not foundTCHAR szfile not found[] = { 'f', 'i', 'l', 'e', ' ', 'n', 'o', 't', ' ', 'f', 'o', 'u', 'n', 'd', '\0' };

 

The above result allows you to use the variable name with slight modification. The source code is as follows:
