Struct SigAlg 

pub struct SigAlg { /* private fields */ }

Algorithm descriptor for EVP_SIGNATURE (OpenSSL 3.2+).

Mirrors DigestAlg / CipherAlg / MacAlg in naming and lifecycle. Used with MessageSigner and MessageVerifier for algorithms such as ML-DSA, SLH-DSA, and Ed25519/Ed448 with context strings.

Implementations

impl SigAlg

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

Fetch an EVP_SIGNATURE by name from the default library context.

Example names: c"ML-DSA-44", c"ED25519", c"SLH-DSA-SHA2-128s".

Errors

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

Fetch an EVP_SIGNATURE by name within a specific library context.

Errors
