Struct pwbox::sodium::Scrypt

pub struct Scrypt {
    pub opslimit: u32,
    pub memlimit: u32,
}

This is supported on crate feature exonum_sodiumoxide only.

Scrypt key derivation function parameterized as per libsodium, i.e., via opslimit (computational hardness) and memlimit (RAM consumption).

Fields

opslimit: u32

Parameter determining the computational hardness of the KDF.

The default value is 1 << 19.

memlimit: u32

Parameter determining the RAM consumption of the KDF. The value is approximately equal to RAM volume in bytes, so, for example, the default value means memory consumption ~16 MB.

The default value is 1 << 24.

Implementations
