C++ 通过boost 获取 md5值

#include

using boost::uuids::detail::md5;


std::string get_md5_string(const std::string input) {
  md5 hash;
  md5::digest_type digest;
  hash.process_bytes(input.data(), input.size());
  hash.get_digest(digest);

  const auto charDigest = reinterpret_cast(&digest);
  std::string result;
  boost::algorithm::hex(charDigest, charDigest + sizeof(md5::digest_type), std::back_inserter(result));
  return result;
}
