Struct Secret

pub struct Secret { /* private fields */ }

Encapsulates a PRF algorithm and secret bytes to be used to derive output.

Implementations

impl Secret

pub fn new( algorithm: &'static Algorithm, secret: &[u8], ) -> Result<Secret, Unspecified>

Constructs a new Secret for use with the associated P_hash Algorithm.

Errors

• Unspecified: If secret.is_empty() == true.

pub fn derive( self, label: &[u8], seed: &[u8], output: usize, ) -> Result<Secret, Unspecified>

Calculates len bytes of TLS PRF using the configured Algorithm, and returns Secret of length len. See RFC5246

Errors

• Unspecified: Returned if the PRF derivation fails.

pub fn derive_with_seed_concatination( self, label: &[u8], seed1: &[u8], seed2: &[u8], len: usize, ) -> Result<Secret, Unspecified>

Calculates len bytes of TLS PRF using the configured Algorithm, and returns Secret of length len.

In this method, seed1 and seed2 will be concatenated together: seed1 || seed2.

See RFC5246

Errors

• Unspecified: Returned if the PRF derivation fails.

Trait Implementations

impl AsRef<[u8]> for Secret

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Debug for Secret

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

Formats the value using the given formatter.

impl Drop for Secret

fn drop(&mut self)

Executes the destructor for this type.

impl<const L: usize> TryFrom<Secret> for [u8; L]

type Error = Unspecified

The type returned in the event of a conversion error.

fn try_from( value: Secret, ) -> Result<[u8; L], <[u8; L] as TryFrom<Secret>>::Error>

Performs the conversion.
