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, see OSSL_STORE-winstore(7)

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