Properties¶

The implementations in this provider specifically has this property defined:

"provider=legacy"

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 any of these properties, except to make sure to get implementations of this provider and none other.
