Struct Cipher 

pub struct Cipher<StreamAlg, BlockAlg>
where
    StreamAlg: KeySizeUser,
{ /* private fields */ }

The Adiantum cipher. Implements KeyInit where key size is equal to key size of the underlying stream cipher.

Implementations

impl<StreamAlg, BlockAlg> Cipher<StreamAlg, BlockAlg>

where StreamAlg: KeyIvInit + StreamCipher, StreamAlg::IvSize: IsGreaterOrEqual<U16>, BlockAlg: BlockEncrypt + BlockSizeUser<BlockSize = U16>,

pub fn encrypt(&self, page: &mut [u8], tweak: &[u8])

page length must be in 0x10..=0x1000 range and divisible by 0x10 tweak must be not greater 0x20

impl<StreamAlg, BlockAlg> Cipher<StreamAlg, BlockAlg>

where StreamAlg: KeyIvInit + StreamCipher, StreamAlg::IvSize: IsGreaterOrEqual<U16>, BlockAlg: BlockDecrypt + BlockSizeUser<BlockSize = U16>,

pub fn decrypt(&self, page: &mut [u8], tweak: &[u8])

page length must be in 0x10..=0x1000 and divisible by 0x10 tweak must be not greater 0x20
