PerimeterX Payload decode & encode functions

px-encode-decode.ts

export interface EncodeOptions {
  shift?: boolean;
  shiftAmount?: number;
  base64?: boolean;
}

export interface DecodeOptions extends EncodeOptions {}

export const decodePayload = (payload: string, options: DecodeOptions = {}): string => {
  let { shift, base64, shiftAmount } = options;
  base64 ??= true;

  for (let i = 0; i < string.length; i++) {
    d += shift ? String.fromCharCode(string.charCodeAt(i) ^ shiftAmount) : string[i];

I tried your code, it partially decoded the final output. Is there anyway to contact you via email?

It was updated to a new encryption; will not be released yet
