Module lib_ctx 

LibCtx — OSSL_LIB_CTX wrapper and Provider — OSSL_PROVIDER wrapper.

Most callers use the global default library context and never need this module. Create an explicit context when:

• FIPS mode is required (load "fips" + "base" providers).
• Per-process isolation of algorithm state is needed.

Arc<LibCtx> ownership

OpenSSL does not expose OSSL_LIB_CTX_up_ref. Rust manages the lifetime via Arc<LibCtx>. Algorithm descriptors that use an explicit context store Option<Arc<LibCtx>> to extend its lifetime.

Structs

LibCtx

An OpenSSL library context (OSSL_LIB_CTX*).

Provider

A loaded OpenSSL provider (OSSL_PROVIDER*).
