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<'a>)`

Password-Based Key Derivation Function 2 (PBKDF2).

`Scrypt(ScryptParams<'a>)`

scrypt sequential memory-hard password hashing function.
