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.
