Trait for AEAD implementations that provide metadata

Required Methods§

Source

fn metadata(&self) -> &'static AeadMetadata

Get the algorithm metadata

Provided Methods§

Source

fn algorithm(&self) -> Algorithm

Get the algorithm identifier

Source

fn key_size(&self) -> usize

Get the key size in bytes

Source

fn nonce_size(&self) -> usize

Get the nonce size in bytes

Source

fn tag_size(&self) -> usize

Get the tag size in bytes

Source

fn security_level(&self) -> u32

Get the security level

Source

fn algorithm_name(&self) -> &'static str

Get the algorithm name

Source

fn algorithm_description(&self) -> &'static str

Get the algorithm description

Source

fn supports_semantic_decrypt(&self) -> bool

Whether this algorithm’s reference stack implements lib_q_core::AeadDecryptSemantic (Layer B), per AeadMetadata::supports_semantic_decrypt.

Custom dyn AeadWithMetadata implementations that are not full algorithm facades should override this to return false when they do not implement semantic decrypt.
