Arduino ascii to hex.

Say, this is your hex number: 0x1c34 or any combination of 0 - 9, A - F or 0 - 9, a - f. It only takes a minute to sign up. You could interpret it in many ways. Often these 7 bits are stored in one byte with the leftmost 8th bit set to 0 and can than be represented by two HEX digits. I need to convert these characters into a HEX string of 20 characters: "0x7E, 0x00, 0x10, 0x17, 0x01, 0x00, 0x13, 0xA2, 0x00, 0x40, 0x63, 0xD9, 0xBB, 0xFF, 0xFE, 0x02, 0x44, 0x31, 0x04, 0x83" Is there a function that will allow me to achieve this.
