android MD5加密方式

32位加密

public static String getMD5(String strSrc) {

		StringBuffer buf = null;
		try {
			MessageDigest md = MessageDigest.getInstance("MD5"); 
			md.update(strSrc.getBytes());
			byte b[] = md.digest(); 
			int i; 
			buf = new StringBuffer(""); 
			for (int offset = 0; offset < b.length; offset++) {
				i = b[offset];
				if(i<0) i+= 256;
				if(i<16)
					buf.append("0");
				buf.append(Integer.toHexString(i));
			}
			// Log.e("555","result: " + buf.toString());//32位的加密 
			//Log.e("555","result: " + buf.toString().substring(8,24));//16位的加密
		} catch (NoSuchAlgorithmException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return buf.toString(); 
	}
