The difference is that: PBKDF2 by design is slow; SHA256 is a good hash function; it is not slow, by design; So if someone were to try a lot of different possible passphrases, say the whole …

Apr 29, 2013 · As far as PBKDF2 iterations in specific, one popular GPU based cracking program can handle with a kitted out modern desktop + 8 GPU's at 1 million tries a second against …

Sep 23, 2016 · From the documentation on pbkdf2_sha256: salt (bytes) Optional salt bytes. If specified, the length must be between 0-1024 bytes. If not specified, a 16 byte salt will be …

Jun 7, 2015 · Attackers are going to use something like oclHashcat, which on a single PC with 8x AMD R9 290Xstock core clock is able to attempt 3.4E12 (2^41) guesses every 30 days …

Jan 13, 2013 · PBKDF2 is a key derivation function: it produces an output of configurable size. For password hashing, you want the size to be large enough to deter generic preimage attacks …

My planned PBKDF2 salt is: a per-user random salt (stored in the clear with each user record) XOR'ed with a global salt. The objective is to increase the cost of brute forcing passwords and …

But the PBKDF2 algorithm that you want to use for password hashing uses PKCS #5 v2 scheme 2 instead. This is why you're getting different results. This is why you're getting different …

Apr 14, 2004 · PBKDF2. You were really close actually. The link you have given shows you how you can call the Rfc2898DeriveBytes function to get PBKDF2 hash results. However, you were …

Sep 6, 2017 · The particularly PBKDF2 implementation you're referencing is only available in .NET Core, not in the full .NET framework. To use PBKDF2 in the framework, you're looking …

Aug 9, 2016 · See this answer for some discussion of bcrypt vs PBKDF2. Though SHA-256-crypt is not PBKDF2, it is similar enough in its performance behaviour on GPU, so the same …
