OSSL_PROVIDER-default - OpenSSL default provider
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.
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

The default provider also includes all of the encoding algorithms present in the
base provider. Some of these have the property "fips=yes", to allow
them to be used together with the FIPS provider.

The RIPEMD160 digest was added to the default provider in OpenSSL 3.0.7.
All other functionality was added in OpenSSL 3.0.
