OSSL_PROVIDER-BASE(7)

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)

In addition to this provider, the "SEED-SRC" algorithm is also available in the default provider.

  Asymmetric Key Encoder

RSA
RSA-PSS
DH
DHX
DSA
EC
ED25519
ED448
X25519
X448
SM2

In addition to this provider, all of these encoding algorithms are also available in the default provider. Some of these algorithms may be used in combination with the FIPS provider.

  Asymmetric Key Decoder

RSA
RSA-PSS
DH
DHX
DSA
EC
ED25519
ED448
X25519
X448
SM2
DER

In addition to this provider, all of these decoding algorithms are also available in the default provider. Some of these algorithms may be used in combination with the FIPS provider.

  Stores

file
org.openssl.winstore

In addition to this provider, all of these store algorithms are also available in the default provider.
