The following code can complete the encryption function. But it introduces a for loop that converts byte[] to List<Byte> . I checked the related issues online. But still can't convert byte[] to List<Byte> via lambda. can you help me? ```java public static String shaEncryption(final String src) { return Optional.ofNullable(src).map(item -> { if (StringUtils.isEmpty(src)) { return null; } try { MessageDigest messageDigest = MessageDigest.getInstance("SHA-512"); messageDigest.update(s.getBytes()); byte[] byteBuffer = messageDigest.digest(); // introduce a for loop List<Byte> list = new ArrayList<>(); for (byte b:byteBuffer){ list.add(b); } String res = list.stream().map(b->Integer.toHexString(0xff & b)).collect(Collectors.joining("")); return res; } catch (Exception e) { throw new ShenyuException(e); } }).orElse(null); } ``` -- This is an automated message from the Apache Git Service.
