Trait Implementations

impl<C, TagSize> AeadCore for Dwp<C, TagSize>

where C: BlockCipherEncrypt + BlockSizeUser<BlockSize = U16>, TagSize: ArraySize + NonZero + IsLessOrEqual<U16, Output = True>,

const TAG_POSITION: TagPosition = TagPosition::Postfix

The AEAD tag position.

type NonceSize = <C as BlockSizeUser>::BlockSize

The length of a nonce.

type TagSize = TagSize

The maximum length of the tag.

impl<C, TagSize> AeadInOut for Dwp<C, TagSize>

where C: BlockCipherEncrypt + BlockSizeUser<BlockSize = U16>, TagSize: ArraySize + NonZero + IsLessOrEqual<U16, Output = True>,

fn encrypt_inout_detached( &self, nonce: &Nonce, associated_data: &[u8], buffer: InOutBuf<'_, '_, u8>, ) -> Result<Tag<Self>>

Encrypt the data in the provided InOutBuf, returning the authentication tag.

fn decrypt_inout_detached( &self, nonce: &Nonce, associated_data: &[u8], buffer: InOutBuf<'_, '_, u8>, tag: &Tag<Self>, ) -> Result<()>

Decrypt the data in the provided InOutBuf, returning an error in the event the provided authentication tag is invalid for the given ciphertext (i.e. ciphertext is modified/unauthentic).

fn encrypt_in_place( &self, nonce: &Array<u8, Self::NonceSize>, associated_data: &[u8], buffer: &mut dyn Buffer, ) -> Result<(), Error>

Encrypt the given buffer containing a plaintext message in-place.

fn decrypt_in_place( &self, nonce: &Array<u8, Self::NonceSize>, associated_data: &[u8], buffer: &mut dyn Buffer, ) -> Result<(), Error>

Decrypt the message in-place, returning an error in the event the provided authentication tag does not match the given ciphertext.

impl<C, TagSize> Debug for Dwp<C, TagSize>

where C: BlockCipherEncrypt + BlockSizeUser<BlockSize = U16>, TagSize: ArraySize + NonZero + IsLessOrEqual<U16, Output = True>,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<C, TagSize> InnerInit for Dwp<C, TagSize>

where C: BlockCipherEncrypt + BlockSizeUser<BlockSize = U16>, TagSize: ArraySize + NonZero + IsLessOrEqual<U16, Output = True>,

fn inner_init(cipher: Self::Inner) -> Self

Initialize value from the inner.

impl<C, TagSize> InnerUser for Dwp<C, TagSize>

where C: BlockCipherEncrypt + BlockSizeUser<BlockSize = U16>, TagSize: ArraySize + NonZero + IsLessOrEqual<U16, Output = True>,

type Inner = C

Inner type.

impl<C, TagSize> ZeroizeOnDrop for Dwp<C, TagSize>

where C: ZeroizeOnDrop + BlockCipherEncrypt + BlockSizeUser<BlockSize = U16>, TagSize: ArraySize + NonZero + IsLessOrEqual<U16, Output = True>,

Available on crate feature zeroize only.
