Question

将java中的md5加密改为用c语言实现；求高手！ 注意：不是字符串通过md5直接得到字符串，详细请看问题补充

这里是java的实现方法：
import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

import sun.misc.BASE64Encoder;

public class EncoderMd5 {

public static void main(String[] arg){
String str="admin1234";
MessageDigest md5;
String encodedStr = null;
try {
md5 = MessageDigest.getInstance("MD5");
BASE64Encoder base64en = new BASE64Encoder();
System.out.println(str.getBytes("utf-8"));
System.out.println(md5.digest(str.getBytes("utf-8")));

encodedStr = base64en.encode(md5.digest(str.getBytes("utf-8")));

} catch (UnsupportedEncodingException e) {

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

e.printStackTrace();
}
System.out.println(encodedStr);
}

}
主要语句为：encodedStr = base64en.encode(md5.digest(str.getBytes("utf-8")));
