利用java自带的实现加密:参考https://jingyan.baidu.com/article/2fb0ba40a2ef2b00f3ec5f74.html
/** * 利用java原生的摘要实现SHA256加密 * @param str 加密后的报文 * @return */ public static String getSHA256StrJava(String str){ MessageDigest messageDigest; String encodeStr = ""; try { messageDigest = MessageDigest.getInstance("SHA-256"); messageDigest.update(str.getBytes("UTF-8")); encodeStr = byte2Hex(messageDigest.digest()); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } return encodeStr; } /** * 将byte转为16进制 * @param bytes * @return */ private static String byte2Hex(byte[] bytes){ StringBuffer stringBuffer = new StringBuffer(); String temp = null; for (int i=0;i<bytes.length;i++){ temp = Integer.toHexString(bytes[i] & 0xFF); if (temp.length()==1){ //1得到一位的进行补0操作 stringBuffer.append("0"); } stringBuffer.append(temp); } return stringBuffer.toString(); }
