Struct RandAlg 

pub struct RandAlg { /* private fields */ }

An OpenSSL RAND algorithm descriptor (EVP_RAND*).

Fetched once and reused to create RandCtx instances.

Implementations

impl RandAlg

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

Fetch a RAND algorithm from the global default library context.

Common algorithm names: c"CTR-DRBG", c"HASH-DRBG", c"HMAC-DRBG".

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 RAND algorithm within an explicit library context.

Use this when the DRBG must be bound to a specific provider set (e.g. a FIPS-isolated LibCtx).

The Arc<LibCtx> is retained for the lifetime of the RandAlg to ensure the context outlives the algorithm descriptor.

Errors

Returns Err if the algorithm is not available in ctx.
