|
|
|
+ * DES 加密算法
|
|
|
+ *
|
|
|
+ * 该函数接受一个 8 字节字符串作为普通 DES 算法的密钥(也就是 64 位,但是算法只使用 56 位),或者接受一个 24 字节字符串作为 3DES
|
|
|
+ * 算法的密钥;第二个参数是要加密或解密的信息字符串;第三个布尔值参数用来说明信息是加密还是解密;接下来的可选参数 mode 如果是 0 表示 ECB
|
|
|
+ * 模式,1 表示 CBC 模式,默认是 ECB 模式;最后一个可选项是一个 8 字节的输入向量字符串(在 ECB 模式下不使用)。返回的密文是字符串。
|
|
|
+ *
|
|
|
+ * 参数: <br>
|
|
|
+ * key: 8字节字符串作为普通 DES 算法的密钥,或 24 字节字符串作为 3DES <br>
|
|
|
+ * message: 加密或解密的信息字符串<br>
|
|
|
+ * encrypt: 布尔值参数用来说明信息是加密还是解密<br>
|
|
|
+ * mode: 1:CBC模式,0:ECB模式(默认)<br>
|
|
|
+ * iv:<br>
|
|
|
+ * padding: 可选项, 8字节的输入向量字符串(在 ECB 模式下不使用)
