## 1. Overview

SMB Direct enables high-performance data transfer using Remote Direct Memory Access (RDMA) technology. This provides ultra-low latency and high bandwidth data transfer by bypassing the traditional TCP/IP stack and allowing direct memory-to-memory transfers between client and server.

## 2. Protocol Specification Reference

- **MS-SMBD**: SMB2 Remote Direct Memory Access (RDMA) Transport Protocol

## 패스워드 해싱

"해싱(Hashing)"은 어떤 내용(여기서는 패스워드)을 해석할 수 없는 일련의 바이트 집합(단순 문자열)으로 변환하는 것을 의미합니다.

동일한 내용(똑같은 패스워드)을 해싱하면 동일한 문자열을 얻습니다.

하지만 그 문자열을 다시 패스워드로 되돌릴 수는 없습니다.

### 패스워드를 해싱하는 이유

데이터베이스를 탈취당하더라도, 침입자는 사용자의 평문 패스워드 대신 해시 값만 얻을 수 있습니다.
