Enum Kdf

Source

#[non_exhaustive]pub enum Kdf {
    Pbkdf2(Pbkdf2Params),
    Scrypt(ScryptParams),
}

Expand description

Password-based key derivation function.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

§

Pbkdf2(Pbkdf2Params)

Password-Based Key Derivation Function 2 (PBKDF2).

§

Scrypt(ScryptParams)

scrypt sequential memory-hard password hashing function.
