Splet10. jun. 2024 · Indeed, if you want to cipher a block of data using AES 128, you need a fixed-length key of 128 bits. Instead, you need to create a cryptographic key of the desired size from the user's password. This is what "Password-Based Key Derivation Function 2" (PBKDF2) does. In .NET, the class that implements this algorithm is Rfc2898DeriveBytes. SpletPBKDF2 ("Password-Based Key Derivation Function 2") is one of the recommended hash-functions for password-hashing. ... A high number of iterations will slow the algorithm down, which makes password cracking a lot harder. A high number of iterations is therefor recommended. PBKDF2 is order of magnitudes slower than MD5 for example. stick and ball shelves https://tambortiz.com
