Struct openssl::symm::Cipher

pub struct Cipher(_);

Represents a particular cipher algorithm.

See OpenSSL doc at EVP_EncryptInit for more information on each algorithms.

Implementations

impl Cipher

pub fn from_nid(nid: Nid) -> Option<Cipher>

Looks up the cipher for a certain nid.

This corresponds to EVP_get_cipherbynid

pub fn nid(&self) -> Nid

Returns the cipher’s Nid.

This corresponds to EVP_CIPHER_nid

pub unsafe fn from_ptr(ptr: *const EVP_CIPHER) -> Cipher

Creates a Cipher from a raw pointer to its OpenSSL type.

Safety

The caller must ensure the pointer is valid for the 'static lifetime.

pub fn as_ptr(&self) -> *const EVP_CIPHER

pub fn key_len(&self) -> usize

Returns the length of keys used with this cipher.

pub fn iv_len(&self) -> Option<usize>

Returns the length of the IV used with this cipher, or None if the cipher does not use an IV.

pub fn block_size(&self) -> usize

Returns the block size of the cipher.

Note

Stream ciphers such as RC4 have a block size of 1.

Trait Implementations

impl Clone for Cipher

fn clone(&self) -> Cipher

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq<Cipher> for Cipher

fn eq(&self, other: &Cipher) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
