Java中Content-MD5的计算方法示例

  
   
     
     
       import java.security.MessageDigest;
import sun.misc.BASE64Encoder;
import java.io.UnsupportedEncodingException;
import java.security.NoSuchAlgorithmException;

public class Md5{
     public static void main(String[] args) {
          try {
                 String exampleString = "blog";
                 MessageDigest messageDigest = MessageDigest.getInstance("MD5"); 
                 BASE64Encoder encoder = new BASE64Encoder(); 
                 String contentMd5 = encoder.encode(messageDigest.digest(exampleString.getBytes("utf-8")));
                 System.out.println("Content-MD5：" + contentMd5);    
          } catch (NoSuchAlgorithmException | UnsupportedEncodingException e) 
          {
                 e.printStackTrace();
          }
     }
}
