Have i Pwned 같은데서 자기 비번 입력 ㄴㄴ
구글에서 검색가능한 비밀번호 안전 측정 사이트들은 입력한 비밀번호를 특정 서버로 전송해 비밀번호와 해시 값을 같이 저장하여 보관하는데, 그리고 사이트,DB서버 관리자가 해시값이나 암호화된 키를 이용해 비밀번호를 검색해볼 수도 있음.
이런 사이트는 입력받은 비밀번호를 MD5와 같은 해시값이나 SHA-1 등을 통한 암호화키로 변환한 후, 이를 같이 저장하는 방식을 취하고 있다.
간단히 말해 내 비밀번호 크래킹을 위한 레인보우 테이블의 일부를 만들어주는 꼴이다.
마찬가지로 랜덤값 암호를 만든다고 Passwordsgenerator같은데서 받은 패스워드 그대로 사용하지 않는것이 좋다.
이유는 앞서 말한 내용과 동일하다.
Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.
Telegram is for everyone who wants fast and reliable messaging and calls. Business users and small teams may like the large groups, usernames, desktop apps and powerful file sharing options. You can appoint admins with advanced tools to help these communities prosper in peace. Public groups can be joined by anyone and are powerful platforms for discussions and collecting feedback.In case you're more into pictures, Telegram has animated gif search, a state of the art photo editor, and an open sticker platform (find some cool stickers here or here). What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.
Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.
