Java中匯入Base64 encode and decode包並使用
public static byte[] base64ToByte(String data) throws IOException {
byte[] apacheBytes=Base64.decodeBase64(data);
return apacheBytes;
}
public static String byteToBase64(byte[] data){ byte[] apacheBytes=Base64.encodeBase64(data); String fromApacheBytes = new String(apacheBytes); return fromApacheBytes; }
在加密演算法中,比如說要對資料庫中的使用者名稱和密碼加密,一般我們會使用salt和SHA1來做,這時候就要用到一些函式。
Base64.decodeBase64
Base64.encodeBase64
這兩個函式如何載入呢?今天晚上正好用到了,寫一下。
從這個網站下下載包,解壓得到
commons-codec-1.8.jar
或者其他版本也可以
然後加到你的eclipse 工程中,右鍵,build path, 加連結
然後就可以在Referenced Libraries中看到了
import後就搞定了。
比如輸入abcdefgh, 加密,解密的結果如下:
[[email protected]
abcdefgh
