How can I get the hex value of a string?

[NOP]

For example, if dat == "dl2beu", then how could I put "646C32626575" in buffer?
If it helps, dat is a string that will always be 6 chars, and buffer is also a string.

Hex value? You mean hash value?

[NOP]

No, I mean a series of the hex values for each ascii character.
0x64 = 'd'
0x6C = 'l'
0x32 = '2'
etc.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

#include <iostream> #include <string> #include <sstream> using namespace std; int main() { string dat = "dl2beu"; ostringstream os; for (int i=0; i<dat.length() ; i++) os << hex << uppercase << (int) dat[i]; string hexdat = os.str(); cout << "Text: " << dat << endl;; cout << "Hex: " << hexdat << endl; return 0; }

Text: dl2beu Hex: 646C32626575

Thanks! Worked perfectly in the full code.

Or the same thing using c-strings

#include <cstdio>
#include <cstring>

using namespace std;

int main()
{
    char dat[] = "dl2beu";
    char hexdat[13];

    sprintf(hexdat, "%X%X%X%X%X%X",
        dat[0], dat[1], dat[2], dat[3], dat[4], dat[5]);

    printf("Text: %s\n", dat);
    printf("Hex:  %s\n", hexdat);

    return 0;
}
