Struct melodies::CipherState

pub struct CipherState<Nonce = u64> {
    pub nonce: Nonce,
    /* private fields */
}

Fields

nonce: Nonce

Note that a nonce of u64::MAX will cause an error on every call to encrypt

Implementations

impl<T> CipherState<T>

pub fn encrypt_with_nonce(&self, n: u64, ad: &[u8], buf: &mut [u8])

Encrypt, with a provided nonce (must prevent reuse). This occurs in place. The last TAG_SIZE bytes of buf will be replaced with the AEAD tag.

pub fn decrypt_with_nonce(
    &self,
    n: u64,
    ad: &[u8],
    buf: &'a mut [u8]
) -> Option<&'a [u8]>

pub fn rekey(&mut self)

impl CipherState<u64>

pub fn into_stateless(self) -> CipherState<()>

pub fn encrypt(&mut self, ad: &[u8], buf: &mut [u8]) -> usize

Returns the size of the encrypted message. Buf should have space for a tag

pub fn decrypt(&mut self, ad: &[u8], buf: &'a mut [u8]) -> Option<&'a [u8]>

Returns the decrypted payload

Trait Implementations

impl<Nonce> Drop for CipherState<Nonce>

fn drop(&mut self)

Executes the destructor for this type.

impl<Nonce> Zeroize for CipherState<Nonce>

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
