Cannot retrieve contributors at this time 346 lines (301 sloc) 10.4 KB Raw Blame SpletGiven that the salt (in this case, as in many cases) is not a secret, and the password is, this seems like the exact opposite of what would ideally be true. An actual pseudo-random function (PRF) would have no problems whatsoever reversing the arguments... and HMAC-SHA256 is conjectured to be a PRF (and presumably so is PBKDF2-HMAC-SHA256).

Splet28. sep. 2024 · HMAC密码碰撞. 如果PBKDF2的PRF使用的是HMAC的话，那么将会发送一些很有意思的问题。对于HMAC来说，如果密码的长度大于HMAC可以接受的范围，那么该密码会首先被做一次hash运算，然后hash过后的字符串会被作为HMAC的输入。 我们举个例子，如果用户输入的密码是： PBKDF2 applies a pseudorandom function, such as hash-based message authentication code (HMAC), to the input password or passphrase along with a salt value and repeats the process many times to produce a derived key, which can then be used as a cryptographic key in subsequent operations. The … Prikaži več In cryptography, PBKDF1 and PBKDF2 (Password-Based Key Derivation Function 1 and 2) are key derivation functions with a sliding computational cost, used to reduce vulnerability to brute-force attacks. PBKDF2 is part of Prikaži več One weakness of PBKDF2 is that while its number of iterations can be adjusted to make it take an arbitrarily large amount of computing time, it can be implemented with a small circuit and very little RAM, which makes brute-force attacks using application-specific integrated circuits Prikaži več • "PKCS #5 v2.1" (PDF).
