    Hi I have this code to send a .txt file between 2 computers, I want to know how can I add simple encryption to it?
    Code:
    #include <stdio>
    #include <conio>
    
    #define CNTRLZ 0x1A
    
    char sourceFileName[] = "H:\\text.txt";
    char commStreamName[] = "COM1";
    FILE *commStream;
    FILE *SouceFile;
    char charToSend;
    char ReadAccess[] = "r";
    char WriteAccess[] = "w";
    char errorMsg[] = "fail to open data file\n";
    char fileopenflag[] = "r";
    char EndOfFile[] = "EOF";
    
    int main(void) {
    FILE *fp;
    FILE *dp;
    int c;
    
    if ((dp = fopen("COM1", "r")) == NULL) {
    printf("fail to open COM port\n"); return 1;
    }
    
    
    if ((fp = fopen( sourceFileName, "w")) == NULL) {
    printf("fail to open data file\n"); return 1;
    }
    
    
    while ((c = fgetc(fp )) != EOF) {
    fputc( c, dp);
    putch(c);
    
    }
    
    fputc('*', dp);
    fclose(dp);
    fclose(fp);
    }
    I don't have a clue and please can someone give me an idea? also where where I stick the code, I'm still a noob.
