使用Apache digest做md5加密的范例

活用Apache commons，使用Apache digest做md5加密的范例。

import java.security.NoSuchAlgorithmException;
import org.apache.commons.codec.digest.DigestUtils;
/**

public class MD5Test {
//加密后的文字串
static final String CHANGEME_MD5_STR = "4cb9c8a8048fd02294477fcb1a41191a";
//被加密的文字串
static final String TARGET = "changeme";

public static void main(String[] argvs){
try {
MessageDigestAdapter adapter = new MessageDigestAdapter("MD5");
String md5str = adapter.digest(TARGET);
System.out.println(md5str);

if(CHANGEME_MD5_STR.equals(md5str)){
System.out.println(md5str + "->" + CHANGEME_MD5_STR);
System.out.println("same with mysql request. length is [" + md5str.length() + "]");

}else{
System.out.println("NOT SAME! with mysql requse");
}

System.out.println("common codec result: " + DigestUtils.md5Hex(TARGET));
if(CHANGEME_MD5_STR.equals(DigestUtils.md5Hex(TARGET))){
System.out.println("code result same with mysql request too. length is [" + DigestUtils.md5Hex(TARGET) + "]");
}

}catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}

}
}
