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
