암호화(AES, RSA, SHA) 관련 이야기

우리 웹서비스에서 비회원과 통신하는 신규 기능을 개발하게 되었다 비회원과 통신이므로 보안에 신경을 많이 썼는데, 그 중 우리가 사용한 AES, RSA, SHA에 대해 이야기 해보려고한다 1.SHA-256 우리는 비회원의 로그인(!?)을 위해, 패스워드를 받았는데, 패스워드는 본인만 알고있어야 하므로, 복호화가 되지 않는 암호화 방법을 채택했다 복호화가 되지 않는 암호화 방법 중 유명한 것이 과거 SHA-0, SHA-1 버전을 거쳐 요즘은 SHA-2를 많이 쓰고있는데, SHA-2에는 SHA-224, SHA-256, SHA-384, SHA-512 등의 종류가 있다 우리는 현재 자주쓰는 SHA-2 중에서도 대표적으로 인터넷뱅킹이나 비트코인등에 쓰이는 SHA-256을 채택했다.

History of HTTPS Usage

"What should I use HTTPS for?" is a question whose answer has changed over the years. Here's an attempt to piece the history together. The web started off as just HTTP. This allowed for an enormous amount of things, but online shopping wasn't one of them. The problem was, sending credit card numbers over HTTP opened them up to theft: anyone between you and the server could keep a copy of your ca
