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.
