输入:PBKDF2接受四个输入参数:密码(password)、盐值(salt)、迭代次数(iteration count)和所需的派生密钥长度(key length)。 伪随机函数:PBKDF2使用一个可配置的伪随机函数(通常是HMAC)来进行计算。 初始化:将密码和盐值连接起来,作为HMAC的输入。 迭代计算:PBKDF2通过多轮迭代计算派生密钥。每一轮迭代都会将上一...

Argon2:Argon2是一种新兴的密钥派生函数,被选为密码哈希竞赛(Password Hashing Competition)的胜出者。与PBKDF2相比,Argon2具有更高的安全性和灵活性,能够抵抗更广泛的攻击,并支持更灵活的参数设置。 scrypt:scrypt是另一种密码哈希函数,与PBKDF2相比,它在抵御硬件加速攻击方面更有优势,因为其计算复杂度依赖于内存,...
