Hex en ligne en texte Decoder

I'am trying to convert the byte array to HEX String. Below is my byte to string conversion method,

public static String toHexString(byte[] bytes) {    char[] hexArray = {'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};    char[] hexChars = new char[bytes.length * 2];    int v;    for ( int j = 0; j < bytes.length; j++ ) {        v = bytes[j] & 0xFF;        hexChars[j*2] = hexArray[v/16];        hexChars[j*2 + 1] = hexArray[v%16];    }    return new String(hexChars);}

The issue is, the data what sender is sending is something like this

00 4A 60 01 02 03 04 02 10 30 38 00 00 0E 80 02 00 00 00 00 00 00 00 00 31 00 00 46 74 16 54 28 12 11 38 33 34 35 31 36 30 30 34 36 37 34 31 36 35 34 32 39 30 30 36 32 37 30 35 35 32 34 00 12 91 0A 59 21 8C DA FB BC D2 52 00 14

and what I'm getting after conversion is something like this

00 4A 60 01 02 03 04 02 10 30 38 00 00 0E EF BF BD 02 00 00 00 00 00 00 00 00 31 00 00 46 74 16 54 28 12 11 38 33 34 35 31 36 30 30 34 36 37 34 31 36 35 34 32 39 30 30 36 32 37 30 35 35 32 34 00 12 EF BF BD

while most of the data is similar, but "EFBFBD" data is coming somehow.

Please help me solve this.

Thanks in advance.

I need to send a command comprised of hex values, like so: "\x06\x01\x00\x44".The string is then encoded into binary, using the built in .encode() function, and sent off into Telnet.

For reasons I do not understand, this does not work if the string is formatted using the other hex formatting (0x instead of \x): "0x060x010x000x44", so I am trying to only use \x.

I need to insert a value into the command before converting it, but I do not know how to take an integer input and convert it into a hexadecimal string literal.

I can do this:

input_int = 100hex_value = hex(input_int)

But that just leaves me with hex_value = '0x64', which is not the same as '\x64'.

Is there a shortcut I am missing, or some way to just turn the int straight into a hex literal string?

(I am using Python 2.7, by the way.)

I have implemented a method that converts a given array of characters into a decimal integer. The method takes every character out of the array, calculates its decimal value and multiplys it with 10^n, where n gets incremeted with every iteration.

So for example the array 4711 would be converted like this. 1*10^0 + 1*10^1 + 7*10^2 + 4*10^3 = 4711 as decimal value.

My question now is how to extend the functionality so the stringTOint method is also able to handle octal and hexal values, e.g. 023 or 0x1A.

/** Converts the given array of characters into a decimal integer */int stringTOint(char str[]) {int i, flag, offset, n,base;flag = 0;base = 10;char c = '0';/*if the first char in the array is '-', the minus flag gets set */if (str[0] == '-') {    flag = -1;}if (flag == -1) {    offset = 1;} else {    offset = 0;}if(offset == 0) {    if (str[0] == '0' && (str[1] != 'x' && str[1] != 'X') ) {        base = 8;  // Octal    } else if (str[0] == '0' && (str[1] == 'x' || str[1] == 'X')) {        base = 16; // Hexadecimal        offset = offset + 2;    }}else if(offset == 1) {    if (str[1] == '0' && (str[2] != 'x' && str[2] != 'X') ) {        base = 8;  // Octal    } else if (str[1] == '0' && (str[2] == 'x' || str[2] == 'X')) {        base = 16; // Hexadecimal        offset = offset + 2;    }}n = 0;/*Loop runs until terminating NULL gets found in array */for (i = offset; str[i] != '\0'; i++) {    n = n * base + str[i] - c;}/*value becomes negative if the negative flag was set */if (flag == -1) {    n = -n;}/* n gets returned */return n;}

To convert String to Hexadecimal i am using:

public String toHex(String arg) {    return String.format("%040x", new BigInteger(1, arg.getBytes("UTF-8")));}

This is outlined in the top-voted answer here:Converting A String To Hexadecimal In Java

How do i do the reverse i.e Hexadecimal to String?

Basically, I am trying to generate the hexadecimal value given the values of Red, Green, and Blue... I am able to convert everything to hex but I would like the outcome to be a 6-digit hexadecimal number that is padded with 0's if there are only 4 outputted digits.

Here's what I have:"

int main() {stringstream hexstring;int red,green,blue;cout << "Red: ";cin >> red;cout << "Green: ";cin >> green;cout << "Blue: ";cin >> blue;hexstring << hex << setfill('0')  << setw(6) << uppercase << red << green  << blue;cout << "#" << hexstring.str();}

Here is the output when I use 0 for Red, 1 for Green, and 43 for blue:

Red: 0Green: 1Blue: 43#00000012B

This adds 6 zeros because my setw is 6. I can set it to 2 zeros to get the total of 6 digits but if I change the values of red, green, blue I would have to also change the value of setw...

How can I make it consistently output a 6 digit number for all values within 255?
