Сигурно хеширайте, шифровайте и потвърждавайте пароли

Поддържането на вашите чувствителни данни заключени и гарантирането, че файловете не са били подправени, е изключително важно. Независимо дали създавате хешове на пароли, кодирате комуникациите си или проверявате контролни суми на файлове, всичко трябва да се прави с първокласна сигурност. Поставяне на лични данни в онлайн бази данни? Голямо не-не, това е просто искане за течове. Ето защо нашият пакет инструменти за сигурност работи изцяло на вашето устройство. Ние използваме вградения в браузъра ви Web Crypto API, за да разбиваме хешове, да създаваме силни пароли и да управляваме криптирането точно там, запазвайки информацията ви поверителна.

Вградената сигурност на вашия браузър: API за уеб крипто

Ние използваме Web Crypto API, който вече е във вашия браузър. Дава ни достъп до всички необходими сигурни криптографски инструменти, така че вашите ключове, хешове и процеси на криптиране да се обработват ефективно и безопасно, направо във вашия браузър.

Лесно хеширане: SHA-256, MD5 и SHA-512

Трябва да се уверите, че даден файл е точно както трябва да бъде? Нашият инструмент за хеширане ви покрива. Той изчислява контролни суми SHA-256, MD5 или SHA-512 направо във вашия браузър. Можете безопасно да сравнявате изтеглените файлове с техните оригинални сигнатури без никакви проблеми.

Генерирайте супер силни пароли, локално

Нашият генератор на пароли изработва сериозно силни, произволни пароли на вашето устройство. Той използва криптографски сигурни генератори на произволни числа (CSPRNG), за да осигури високо ниво на непредсказуемост, поддържайки вашите акаунти допълнително безопасни.

Шифроване и дешифриране с AES и Triple DES

Заключете вашите обикновени текстови съобщения или ги отключете сигурно с AES-256 или Triple DES. Цялата тежка работа се случва точно на компютъра ви и ние изтриваме всички временни данни от паметта в момента, в който приключи.

Сканирайте и създавайте QR кодове сигурно

Нашият инструмент за QR код обработва както генерирането, така и сканирането на баркодове направо на вашето устройство. Емисията на камерата се обработва в раздела на вашия браузър, така че връзките се декодират, без да изпращате никакви данни другаде.

Как да използвате - Процес стъпка по стъпка

  1. стъпка 1

    Изберете своя инструмент

    Просто изберете това, от което се нуждаете – независимо дали е конкретен хеш алгоритъм (като SHA-256), шифър за криптиране или настройки за новата ви парола.

  2. стъпка 2

    Добавете вашите данни

    Въведете текста си, качете файл или ни кажете колко дълга искате да бъде вашата парола.

  3. стъпка 3

    Всичко се случва тук

    Web Crypto API върши цялата тежка работа, разбивайки числата директно в паметта на вашия браузър.

  4. стъпка 4

    Копирайте с увереност

    Вземете вашата защитена парола, хеш или криптиран текст. Ние незабавно изчистваме локалната памет, след като сте готови.

Често задавани въпроси

Всичко, което трябва да знаете за нашата сигурност и поверителност

Трябва ли да кача файловете си на сървър, за да получа хешове?
не! Инструментът за хеширане чете вашия файл директно от вашия браузър като ArrayBuffer и изчислява контролната сума направо на вашето устройство. Това е напълно безопасно за вашите лични файлове.
Каква е голямата работа с CSPRNG в сравнение с обикновените произволни генератори?
Мислете за стандартните генератори (като `Math.random`) като за малко предвидими. CSPRNG, от друга страна, използва произволност от реалния свят от вашата система, за да създаде стойности, които са невероятно трудни за отгатване, което ги прави достатъчно сигурни за криптография.
Наистина ли е безопасно да дешифрирам чувствителни съобщения с помощта на инструмента AES в моя браузър?
Абсолютно! Цялата магия се случва направо в раздела на вашия браузър, така че вашият ключ за дешифриране и шифрован текст се обработват локално и не оставят следи онлайн.
Защо трябва да проверя SHA-256 контролната сума на файл?
Проверката на SHA-256 хеша на файл е интелигентен начин да се уверите, че той не е бил манипулиран или повреден. Това е като цифров пръстов отпечатък, който потвърждава, че вашето изтегляне е точно това, което трябва да бъде, запазвайки вашите файлове защитени.
Скенерът за QR код запазва ли потока от камерата ми?
Не, абсолютно не! Кадрите на вашата камера се обработват и декодират направо на вашето устройство в реално време, след което незабавно се изхвърлят. Ние даваме приоритет на вашата пълна поверителност.
Мога ли да генерирам пароли, които изключват подобни знаци?
Вие залагате! Можете лесно да изберете опции за изключване на трудни знаци като „I“, „l“, „1“, „O“ и „0“. Това помага за предотвратяване на объркване или грешки при четливост, когато въвеждате новата си парола.
Какво е информационна ентропия и каква е връзката й с паролите?
Мислете за ентропията като мярка за това колко непредсказуема е вашата парола. Колкото по-висока е ентропията, толкова по-математически е трудно за всеки да отгатне или грубо да си проправи път.
Мога ли да стартирам тези инструменти за сигурност офлайн?
Със сигурност можете! След като нашето уеб приложение се зареди във вашия браузър, вие сте свободни да прекъснете връзката с интернет. Всички наши криптографски инструменти ще продължат да работят перфектно офлайн.
