NAME
OSSL_PROVIDER-default - OpenSSL default provider
DESCRIPTION
The OpenSSL default provider supplies the majority of OpenSSL's diverse algorithm implementations. If an application doesn't specify anything else explicitly (e.g. in the application or via config), then this is the provider that will be used as fallback: It is loaded automatically the first time that an algorithm is fetched from a provider or a function acting on providers is called and no other provider has been loaded yet. If an attempt to load a provider has already been made (whether successful or not) then the default provider won't be loaded automatically. Therefore if the default provider is to be used in conjunction with other providers then it must be loaded explicitly. Automatic loading of the default provider only occurs a maximum of once; if the default provider is explicitly unloaded then the default provider will not be automatically loaded again. Properties The implementations in this provider specifically have this property defined: "provider=default" It may be used in a property query string with fetching functions such as EVP_MD_fetch(3) or EVP_CIPHER_fetch(3), as well as with other functions that take a property query string, such as EVP_PKEY_CTX_new_from_name(3). It isn't mandatory to query for this property, except to make sure to get implementations of this provider and none other. Some implementations may define additional properties. Exact information is listed below
