Struct tink_prf::Set

pub struct Set {
    pub primary_id: u32,
    pub prfs: HashMap<u32, Box<dyn Prf>>,
}

Set is a set of PRFs. A Keyset can be converted into a set of PRFs using this primitive. Every key in the keyset corresponds to a PRF in the prf.Set. Every PRF in the set is given an ID, which is the same ID as the key id in the Keyset.

Fields

primary_id: u32

The key ID marked as primary in the corresponding Keyset.

prfs: HashMap<u32, Box<dyn Prf>>

Map key IDs to their corresponding Prf.

Implementations

impl Set

pub fn new(h: &Handle) -> Result<Set, TinkError>

Create a Set from the given keyset handle.

pub fn compute_primary_prf(
    &self,
    input: &[u8],
    output_length: usize
) -> Result<Vec<u8>, TinkError>

Equivalent to self.prfs[set.primary_id].compute_prf(input, output_length).
