OSSL_PROVIDER-BASE(7)               OpenSSL              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:

   Asymmetric Key Encoder
       In addition to "provider=base", some of these encoders define the
       property "fips=yes", to allow them to be used together with the FIPS
       provider.
