Struct Cipher

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

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 aes_128_ecb() -> Cipher

pub fn aes_128_cbc() -> Cipher

pub fn aes_128_ctr() -> Cipher

pub fn aes_128_gcm() -> Cipher

pub fn aes_128_ofb() -> Cipher

pub fn aes_192_ecb() -> Cipher

pub fn aes_192_cbc() -> Cipher

pub fn aes_192_ctr() -> Cipher

pub fn aes_192_gcm() -> Cipher

pub fn aes_192_ofb() -> Cipher

pub fn aes_256_ecb() -> Cipher

pub fn aes_256_cbc() -> Cipher

pub fn aes_256_ctr() -> Cipher

pub fn aes_256_gcm() -> Cipher

pub fn aes_256_ofb() -> Cipher

pub fn des_cbc() -> Cipher

pub fn des_ecb() -> Cipher

pub fn des_ede3() -> Cipher

pub fn des_ede3_cbc() -> Cipher

pub fn rc4() -> Cipher

pub unsafe fn from_ptr(ptr: *const evp_cipher_st) -> 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_st

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 duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for Cipher

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for Cipher

impl Send for Cipher

impl StructuralPartialEq for Cipher
