docs: Decodes/deobfuscates an encoded password. Although this does not prevent
  actual hacking of password, it does remove the obvious threats of having
  passwords stored as clear text.
  
  @param encodedPassword
  @return a char array containing the password. Do not use this as a
  long-lived object. If the password needs to be held in memory for
  longer periods, the encoded version is recommended.
