Struct openssl::derive::Deriver [−][src]
pub struct Deriver<'a>(_, _);
A type used to derive a shared secret between two keys.
Methods
impl<'a> Deriver<'a>[src]
impl<'a> Deriver<'a>pub fn new<T>(key: &'a PKeyRef<T>) -> Result<Deriver<'a>, ErrorStack> where
T: HasPrivate, [src]
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.
pub fn set_peer<T>(&mut self, key: &'a PKeyRef<T>) -> Result<(), ErrorStack> where
T: HasPublic, [src]
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:
pub fn len(&mut self) -> Result<usize, ErrorStack>[src]
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.
pub fn derive(&mut self, buf: &mut [u8]) -> Result<usize, ErrorStack>[src]
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.
pub fn derive_to_vec(&mut self) -> Result<Vec<u8>, ErrorStack>[src]
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.
