今天对接第三方突然用到这个加密方式了,找了一些资料都没有特别好的,所以研究了一下找了到了两种加密,分享一下。
maven:
<dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>${common-codec.version}</version></dependency>
public static String getSHA256Str(String str){ MessageDigest messageDigest; String encdeStr = ""; try { messageDigest = MessageDigest.getInstance("SHA-256"); byte[] hash = messageDigest.digest(str.getBytes("UTF-8")); encdeStr = Hex.encodeHexString(hash); } catch (NoSuchAlgorithmException e) { e.printStackTrace(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } return encdeStr;}
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;}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();}
