Struct CipherRef 

pub struct CipherRef(/* private fields */);

A reference to a Cipher.

Implementations

impl CipherRef

pub fn nid(&self) -> Nid

Returns the cipher’s Nid.

This corresponds to EVP_CIPHER_nid.

pub fn key_length(&self) -> usize

Returns the length of keys used with this cipher.

This corresponds to EVP_CIPHER_key_length.

pub fn iv_length(&self) -> usize

Returns the length of the IV used with this cipher.

Note

Ciphers that do not use an IV have an IV length of 0.

This corresponds to EVP_CIPHER_iv_length.

pub fn block_size(&self) -> usize

Returns the block size of the cipher.

Note

Stream ciphers have a block size of 1.

This corresponds to EVP_CIPHER_block_size.

Trait Implementations

impl ForeignTypeRef for CipherRef

type CType = EVP_CIPHER

The raw C type.

unsafe fn from_ptr<'a>(ptr: *mut Self::CType) -> &'a Self

Constructs a shared instance of this type from its raw type.

unsafe fn from_ptr_mut<'a>(ptr: *mut Self::CType) -> &'a mut Self

Constructs a mutable reference of this type from its raw type.

fn as_ptr(&self) -> *mut Self::CType

Returns a raw pointer to the wrapped value.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
