pub struct Deriver<'a>(_, _);Expand description
A type used to derive a shared secret between two keys.
Implementations
sourceimpl<'a> Deriver<'a>
impl<'a> Deriver<'a>
sourcepub fn new<T>(key: &'a PKeyRef<T>) -> Result<Deriver<'a>, ErrorStack>where
T: HasPrivate,
pub fn new<T>(key: &'a PKeyRef<T>) -> Result<Deriver<'a>, ErrorStack>where
T: HasPrivate,
Creates a new Deriver using the provided private key.
This corresponds to EVP_PKEY_derive_init.
sourcepub fn set_peer<T>(&mut self, key: &'a PKeyRef<T>) -> Result<(), ErrorStack>where
T: HasPublic,
pub fn set_peer<T>(&mut self, key: &'a PKeyRef<T>) -> Result<(), ErrorStack>where
T: HasPublic,
Sets the peer key used for secret derivation.
This corresponds to EVP_PKEY_derive_set_peer:
sourcepub fn len(&mut self) -> Result<usize, ErrorStack>
pub fn len(&mut self) -> Result<usize, ErrorStack>
Returns the size of the shared secret.
It can be used to size the buffer passed to Deriver::derive.
This corresponds to EVP_PKEY_derive.
sourcepub fn derive(&mut self, buf: &mut [u8]) -> Result<usize, ErrorStack>
pub fn derive(&mut self, buf: &mut [u8]) -> Result<usize, ErrorStack>
Derives a shared secret between the two keys, writing it into the buffer.
Returns the number of bytes written.
This corresponds to EVP_PKEY_derive.
sourcepub fn derive_to_vec(&mut self) -> Result<Vec<u8>, ErrorStack>
pub fn derive_to_vec(&mut self) -> Result<Vec<u8>, ErrorStack>
A convenience function which derives a shared secret and returns it in a new buffer.
This simply wraps Deriver::len and Deriver::derive.
