6 OSSL_PROVIDER-default - OpenSSL default provider
7
9 The OpenSSL default provider supplies the majority of OpenSSL's diverse
10 algorithm implementations. If an application doesn't specify anything
11 else explicitly (e.g. in the application or via config), then this is
12 the provider that will be used as fallback: It is loaded automatically
13 the first time that an algorithm is fetched from a provider or a
14 function acting on providers is called and no other provider has been
15 loaded yet.
16 If an attempt to load a provider has already been made (whether
18 successful or not) then the default provider won't be loaded
19 automatically. Therefore if the default provider is to be used in
20 conjunction with other providers then it must be loaded explicitly.
21 Automatic loading of the default provider only occurs a maximum of
22 once; if the default provider is explicitly unloaded then the default
23 provider will not be automatically loaded again.
24 Properties
26 The implementations in this provider specifically have this property
27 defined:
28 "provider=default"
30 It may be used in a property query string with fetching functions such
32 as EVP_MD_fetch(3) or EVP_CIPHER_fetch(3), as well as with other
33 functions that take a property query string, such as
34 EVP_PKEY_CTX_new_from_name(3).
35 It isn't mandatory to query for this property, except to make sure to
37 get implementations of this provider and none other.
38 Some implementations may define additional properties. Exact
40 information is listed below

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

146 The RIPEMD160 digest was added to the default provider in OpenSSL
147 3.0.7.
148 All other functionality was added in OpenSSL 3.0.
