What is the technology behind F-Secure KEY? - F-Secure Community
<main> <article class="userContent"> <p> </p>What is the technology behind F-Secure KEY? <p>To protect your sensitive data, F-Secure KEY uses the Advanced Encryption Standard with a key size of 256 bits. This algorithm works in the CCM mode for encryption; CCM is an acronym for a longer abbreviation, namely CTR mode with CBC-MAC. CTR stands for Counter, CBC stands for Cipher Block Chaining, and MAC stands for Message Authentication Code. Nowadays, AES is the recommended standard for modern data encryption. </p> <p>The master encryption key is derived from your master password using the Password-Based Key Derivation Function 2 (PBKDF2) algorithm specified in the Public-Key Cryptography Standards (PKCS) #5; in the PBKDF2 algorithm, we use the Hash-based Message Authentication Code (HMAC) SHA256, random salts and 20,000 of iterations. This makes it much more difficult to recover the keys through Brute-force or Dictionary attacks, even for weaker passwords. </p> <div id="related"> <strong>Related information</strong> <ul><li><a rel="nofollow" href="https://community.f-secure.com/key-en/kb/articles/5033"> F-Secure KEY in a nutshell </a></li> <li><a rel="nofollow" href="https://community.f-secure.com/key-en/kb/articles/5046"> What are the system requirements for F-Secure KEY for desktop computers? </a></li> <li><a rel="nofollow" href="https://community.f-secure.com/key-en/kb/articles/5050"> What are the system requirements for F-Secure KEY for mobile devices? </a></li></ul></div> <br> </article> </main>
