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

§Safety

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

source

pub fn key_len(&self) -> usize

Returns the length of keys used with this cipher.

source

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.

impl PartialEq for Cipher

source§

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