SpletPBKDF2¶. PBKDF2 is the most widespread algorithm for deriving keys from a password, originally defined in version 2.0 of the PKCS#5 standard or in RFC2898.. It is computationally expensive (a property that can be tuned via the count parameter) so as to thwart dictionary and rainbow tables attacks. However, it uses a very limited amount of … Splet22. jun. 2024 · PBKDF2(Password-Based Key Derivation Function)。通过哈希算法进行加密。由于哈希算法是单向的，能够将不论什么大小的数据转化为定长的“指纹”，并且无法被反向计算。另外，即使数据源仅仅修改了一丁点。哈希的结果也会全然不同。
