NAME
OSSL_PROVIDER-base - OpenSSL base provider
DESCRIPTION
The OpenSSL base provider supplies the encoding for OpenSSL's asymmetric
cryptography.
Properties
The implementations in this provider specifically have this property
defined:
"provider=base"
It may be used in a property query string with fetching functions.
It isn't mandatory to query for this property, except to make sure to
get implementations of this provider and none other.
"type=parameters"
"type=private"
"type=public"
These may be used in a property query string with fetching functions to
select which data are to be encoded. Either the private key material,
the public key material or the domain parameters can be selected.
"format=der"
"format=pem"
"format=text"
These may be used in a property query string with fetching functions to
select the encoding output format. Either the DER, PEM and plaintext
are currently permitted.
OPERATIONS AND ALGORITHMS
The OpenSSL base provider supports these operations and algorithms:
Random Number Generation
SEED-SRC, see EVP_RAND-SEED-SRC(7)
JITTER, see EVP_RAND-JITTER(7)
In addition to this provider, the "SEED-SRC" and "JITTER" algorithms are
also available in the default provider.
