Struct MacAlg 

pub struct MacAlg { /* private fields */ }

An OpenSSL MAC algorithm descriptor (EVP_MAC*).

Fetched once and reused. Implements Clone via EVP_MAC_up_ref.

Implementations

impl MacAlg

pub fn fetch(name: &CStr, props: Option<&CStr>) -> Result<Self, ErrorStack>

Fetch a MAC algorithm from the global default library context.

Errors

Returns Err if the algorithm is not available.

pub fn fetch_in( ctx: &Arc<LibCtx>, name: &CStr, props: Option<&CStr>, ) -> Result<Self, ErrorStack>

Fetch a MAC algorithm from an explicit library context.

Errors

pub fn as_ptr(&self) -> *const EVP_MAC

Return the raw EVP_MAC* pointer. Valid for the lifetime of self.

pub fn name(&self) -> &CStr

Return the canonical name of this MAC algorithm (e.g. "HMAC", "CMAC").

The returned reference is valid for the lifetime of self.
