/** 
* 去掉字符串的換行符號(hào) 
* base64編碼3-DES的數(shù)據(jù)時(shí)，得到的字符串有換行符號(hào)，根據(jù)需要可以去掉

6、對(duì)字符串進(jìn)行URLDecoder.encode(strEncoding)編碼

復(fù)制代碼代碼如下:

/** 
* 對(duì)字符串進(jìn)行URLDecoder.encode(strEncoding)編碼 
* @param String src 要進(jìn)行編碼的字符串 
* 
* @return String 進(jìn)行編碼后的字符串 
*/

{ 
String requestValue=""; 
try{ 

requestValue = URLEncoder.encode(src); 
} 
catch(Exception e){ 
e.printStackTrace(); 
} 

return requestValue; 
} 

7、對(duì)字符串進(jìn)行URLDecoder.decode(strEncoding)解碼

復(fù)制代碼代碼如下:

/** 
* 對(duì)字符串進(jìn)行URLDecoder.decode(strEncoding)解碼 
* @param String src 要進(jìn)行解碼的字符串 
* 
* @return String 進(jìn)行解碼后的字符串 
*/ 
public String getURLDecoderdecode(String src) 
{ 
String requestValue=""; 
try{ 

requestValue = URLDecoder.decode(src); 
} 
catch(Exception e){ 
e.printStackTrace(); 
} 

return requestValue; 
} 

8、進(jìn)行3-DES解密（密鑰匙等同于加密的密鑰匙）

復(fù)制代碼代碼如下:

/** 
* 
*進(jìn)行3-DES解密（密鑰匙等同于加密的密鑰匙）。 
* @param byte[] src 要進(jìn)行3-DES解密byte[] 
* @param String spkey分配的SPKEY 
* @return String 3-DES解密后的String 
*/

{ 
String strDe = null;

try 
{ 
cipher=Cipher.getInstance("DESede"); 
byte[] key = getEnKey(spKey); 
DESedeKeySpec dks = new DESedeKeySpec(key); 
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DESede"); 
SecretKey sKey = keyFactory.generateSecret(dks); 
cipher.init(Cipher.DECRYPT_MODE, sKey); 
byte ciphertext[] = cipher.doFinal(debase64); 
strDe = new String(ciphertext,"UTF-16LE"); 
} 
catch(Exception ex) 
{ 
strDe = ""; 
ex.printStackTrace(); 
}
