Struct PasswordHashConfig 

pub struct PasswordHashConfig {
    pub memory_cost: u32,
    pub iterations: u32,
    pub parallelism: u32,
    pub output_length: usize,
}

Configuration for Argon2id password hashing

These parameters control the computational cost of hashing and verification. Higher values provide better security but require more resources.

Defaults

The defaults follow OWASP recommendations for server-side password hashing:

• Memory cost: 19456 KiB (~19 MB)
• Iterations: 2
• Parallelism: 1
• Output length: 32 bytes

Fields

memory_cost: u32

Memory cost in KiB (default: 19456 = ~19 MB)

Higher values make attacks more expensive. OWASP recommends at least 12 MiB.

iterations: u32

Number of iterations (default: 2)

Higher values increase computation time. OWASP recommends at least 2.

parallelism: u32

Degree of parallelism (default: 1)

Number of parallel threads to use. Typically set to available CPU cores.

output_length: usize

Output hash length in bytes (default: 32)
