}Expand description
This trait encapsulates all cipher-specific behavior.
Provided Associated Constants§
Sourceconst BLOCK_SIZE: usize = 16usize
const BLOCK_SIZE: usize = 16usize
Processing block size (always 16 bytes for AES).
Sourceconst REQUIRES_PADDING: bool = false
const REQUIRES_PADDING: bool = false
Indicates whether the cipher requires the application to provide padding.
Required Methods§
Provided Methods§
Sourcefn chmod_bits(&self) -> u8
fn chmod_bits(&self) -> u8
Returns the raw CHMOD field value for this cipher mode.
Sourcefn get_header_block(&self) -> &[u8]
fn get_header_block(&self) -> &[u8]
Returns the AAD header block as required by the cipher (for authenticated modes).
Sourcefn uses_gcm_phases(&self) -> bool
fn uses_gcm_phases(&self) -> bool
Indicates whether this cipher mode uses GCM/CCM phases (init, header, payload, final).
Sourcefn is_ccm_mode(&self) -> bool
fn is_ccm_mode(&self) -> bool
Indicates whether this is CCM mode (which has different final phase handling).
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
