=head1 NAME
|
|
|
|
OSSL_PROVIDER-default - OpenSSL default provider
|
|
|
|
=head1 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.
|
|
|
|
=head2 Properties
|
|
|
|
The implementations in this provider specifically have this property
|
|
defined:
|
|
|
|
=over 4
|
|
|
|
=item "provider=default"
|
|
|
|
=back
|
|
|
|
It may be used in a property query string with fetching functions such as
|
|
L<EVP_MD_fetch(3)> or L<EVP_CIPHER_fetch(3)>, as well as with other
|
|
functions that take a property query string, such as
|
|
L<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.
