OSSL_PROVIDER-default

NAME

OSSL_PROVIDER-default - OpenSSL default provider

DESCRIPTION

The OpenSSL default provider supplies the majority of OpenSSL's diverse algorithm implementations. It also acts as a fallback when no other provider has been loaded.

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
