What is a ascii to hexadecimal converter?

This tool takes plain-text ASCII data as input and converts it to hexadecimal base. Hex numbers can be prefixed with "0x" base prefix and they can be separated by a space for better readability and they can be padded with a zero so that each hex number has two nybbles.
