API

hexToStr(hex: string): string | false

Decode a hexadecimal string

isHex(hex: string, stric?: boolean): boolean

Validate a hexadecimal string.

  • strict: If enabled, this will return false if the string length is not divisible by 2 (invalid hexadecimal string length). If you disabled it, you can validate strings with any length. Check the following example. (default: true)
   hexyjs.isHex("1"); // strict enabled  
   // => false

   hexyjs.isHex("1", false); // strict disabled  
   // => true

strToHex(str: string, options?: strToHexOptions): string

Encode a string to a hexadecimal string. You can use this function with options to change the output.

  • grouped: Enable/disable grouped output. (default: false)
  • uppercase: Enable/disable the uppercase output. (default: false)
strToHexOptions {
    uppercase?: boolean,
    grouped?: boolean
}
    hexyjs.strToHex("Cave Story", { uppercase: true });
    // => 436176652053746F7279

    hexyjs.strToHex("Cave Story", { grouped: true });
    // => 43 61 76 65 20 53 74 6f 72 79
