采用普通的編碼方式給密碼加密并不能有效地保護密碼。
當密碼以明文形式存儲在應用程序的屬性文件或其他配置文件中時，會發生 password management 漏洞。程序員試圖通過編碼函數來遮蔽密碼，以修補 password management 漏洞，例如使用 64 位基址編碼方式，但都不能起到充分保護密碼的作用。
示例：以下代碼用 hardcoded password 來連接應用程序和提取地址簿條目：
...
obj = new XMLHttpRequest();
obj.open('GET','/fetchusers.jsp?id='+form.id.value,'true','scott','tiger');
