Struct mls_rs_crypto_openssl::kdf::Kdf

pub struct Kdf { /* private fields */ }

Implementations

impl Kdf

pub fn new(cipher_suite: CipherSuite) -> Option<Self>

Methods from Deref<Target = MdRef>

pub fn block_size(&self) -> usize

Returns the block size of the digest in bytes.

This corresponds to EVP_MD_block_size.

pub fn size(&self) -> usize

Returns the size of the digest in bytes.

This corresponds to EVP_MD_size.

pub fn type_(&self) -> Nid

Returns the Nid of the digest.

This corresponds to EVP_MD_type.

Trait Implementations

impl Clone for Kdf

fn clone(&self) -> Kdf

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Kdf

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for Kdf

type Target = MdRef

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl KdfType for Kdf

fn expand( &self, prk: &[u8], info: &[u8], len: usize ) -> Result<Vec<u8>, KdfError>

Warning

The length of info can not exceed 1024 bytes when using the OpenSSL Engine due to underlying restrictions in OpenSSL. This function will throw an OpensslError in the event info is > 1024 bytes.

type Error = KdfError

fn extract(&self, salt: &[u8], ikm: &[u8]) -> Result<Vec<u8>, KdfError>

fn extract_size(&self) -> usize

fn kdf_id(&self) -> u16

KDF Id, as specified in RFC 9180, Section 5.1 and Table 3.
