Hash, kryptera och verifiera lösenord på ett säkert sätt

Att hålla dina känsliga data låsta och se till att filer inte har manipulerats är superviktigt. Oavsett om du skapar lösenordshashar, förvränger din kommunikation eller kontrollerar filkontrollsummor, måste allt göras med förstklassig säkerhet. Klistra in privata uppgifter i onlinedatabaser? Stort nej-nej, det är bara att fråga efter läckor. Det är därför vår Security Tools-svit fungerar helt på din enhet. Vi använder din webbläsares inbyggda webbkrypterings-API för att knäcka hash, skapa starka lösenord och hantera kryptering där, för att hålla din information privat.

Din webbläsares inbyggda säkerhet: Web Crypto API

Vi använder Web Crypto API som redan finns i din webbläsare. Det ger oss tillgång till alla säkra kryptografiska verktyg som behövs, så att dina nycklar, hash- och krypteringsprocesser hanteras effektivt och säkert, direkt i din webbläsare.

Hashing på ett enkelt sätt: SHA-256, MD5 och SHA-512

Behöver du se till att en fil är exakt som den ska vara? Vårt hashverktyg har dig täckt. Den beräknar SHA-256, MD5 eller SHA-512 kontrollsummor direkt i din webbläsare. Du kan säkert jämföra nedladdade filer med deras ursprungliga signaturer utan krångel.

Generera superstarka lösenord, lokalt

Vår lösenordsgenerator skapar seriöst starka, slumpmässiga lösenord på din enhet. Den använder kryptografiskt säkra slumptalsgeneratorer (CSPRNG) för att säkerställa en hög nivå av oförutsägbarhet, vilket håller dina konton extra säkra.

Kryptera och dekryptera med AES & Triple DES

Lås ner dina vanliga textmeddelanden eller lås upp dem säkert med AES-256 eller Triple DES. Alla tunga lyft sker direkt på din dator, och vi raderar all temporär data från minnet så fort det är klart.

Skanna och skapa QR-koder säkert

Vårt QR-kodverktyg hanterar både att generera och skanna streckkoder direkt på din enhet. Kameraflödet bearbetas i din webbläsarflik, så länkar avkodas utan att någon av dina data skickas någon annanstans.

Hur man använder - steg-för-steg-process

  1. Steg 1

    Välj ditt verktyg

    Välj bara vad du behöver – oavsett om det är en specifik hashalgoritm (som SHA-256), ett krypteringschiffer eller inställningar för ditt nya lösenord.

  2. Steg 2

    Lägg till din input

    Skriv in din text, ladda upp en fil eller berätta hur långt du vill att ditt lösenord ska vara.

  3. Steg 3

    Allt händer här

    Web Crypto-API:et gör allt det tunga arbetet och knackar siffrorna direkt i din webbläsares minne.

  4. Steg 4

    Kopiera med förtroende

    Ta ditt säkra lösenord, hash eller krypterad text. Vi rensar omedelbart det lokala minnet när du är klar.

Vanliga frågor

Allt du behöver veta om vår säkerhet och integritet

Behöver jag ladda upp mina filer till en server för att få hash?
Nej! Hashingverktyget läser din fil direkt från din webbläsare som en ArrayBuffer och beräknar kontrollsumman direkt på din enhet. Det är helt säkert för dina privata filer.
Vad är grejen med CSPRNG jämfört med vanliga slumpgeneratorer?
Tänk på att standardgeneratorer (som `Math.random`) är lite förutsägbara. En CSPRNG, å andra sidan, använder verklig slumpmässighet från ditt system för att skapa värden som är otroligt svåra att gissa, vilket gör dem tillräckligt säkra för kryptografi.
Är det verkligen säkert att dekryptera känsliga meddelanden med AES-verktyget i min webbläsare?
Absolut! All magi sker direkt i din webbläsarflik, så din dekrypteringsnyckel och chiffertext bearbetas lokalt och lämnar inga spår på nätet.
Varför ska jag verifiera SHA-256-kontrollsumman för en fil?
Att verifiera en fils SHA-256-hash är ett smart sätt att se till att den inte har manipulerats eller skadats. Det är som ett digitalt fingeravtryck som bekräftar att din nedladdning är precis vad den ska vara, och håller dina filer säkra.
Sparar QR-kodskannern min kameraström?
Nej, absolut inte! Dina kameraramar bearbetas och avkodas direkt på din enhet i realtid och kasseras sedan omedelbart. Vi prioriterar din fullständiga integritet.
Kan jag skapa lösenord som utesluter liknande tecken?
Du slår vad! Du kan enkelt välja alternativ för att utesluta knepiga tecken som "I", "l", "1", "O" och "0". Detta hjälper till att förhindra förvirring eller läsbarhetsfel när du skriver ditt nya lösenord.
Vad är informationsentropi och hur relaterar det till lösenord?
Tänk på entropi som ett mått på hur oförutsägbart ditt lösenord är. Ju högre entropin är, desto mer matematiskt svårare är det för vem som helst att gissa eller brutalt tvinga sig in.
Kan jag köra dessa säkerhetsverktyg offline?
Det kan du säkert! När vår webbapplikation väl har laddats i din webbläsare är du fri att koppla från internet. Alla våra kryptografiska verktyg kommer att fortsätta fungera perfekt offline.
