Struct PasswordHashConfig

pub struct PasswordHashConfig {
    pub mem_cost: u32,
    pub time_cost: u32,
    pub lanes: u32,
    pub hash_length: usize,
}

Configuration for Argon2 password hashing parameters.

Fields

mem_cost: u32

Memory cost in kibibytes (1 KiB = 1024 bytes). Higher values increase resistance to brute-force attacks. Recommended: at least 65536 (64 MiB) in production environments.

time_cost: u32

Number of iterations (aka time cost). Higher values increase CPU effort. Recommended: at least 3 for most applications.

lanes: u32

Degree of parallelism (number of threads/lanes to use). Usually matches the number of CPU cores available.

hash_length: usize

Desired length of the resulting password hash in bytes. Common values are 32 (256 bits) or 64 (512 bits).
