采用一些簡單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：以下代碼可以從屬性文件中讀取密碼，并使用該密碼連接到數據庫。
...
01 RECORD.
05 UID PIC X(10).
05 PWD PIC X(10).
...
EXEC CICS
READ
FILE('CFG')
INTO(RECORD)
RIDFLD(ACCTNO)
...
END-EXEC.
PERFORM BASE-64-ENCODING.
EXEC SQL
CONNECT :UID
IDENTIFIED BY :PWD
AT :MYCONN
USING :MYSERVER
END-EXEC.
...
CFG 具有訪問權限的人都能讀取密碼的值，并且很容易確定這個值是否經過 64 位基址編碼。而這給了心懷不軌的雇員利用這一信息破壞系統的機會。
