 | =head1 NAME | 
 |  | 
 | OSSL_PROVIDER-base - OpenSSL base provider | 
 |  | 
 | =head1 DESCRIPTION | 
 |  | 
 | The OpenSSL base provider supplies the encoding for OpenSSL's | 
 | asymmetric cryptography. | 
 |  | 
 | =head2 Properties | 
 |  | 
 | The implementations in this provider specifically have this property | 
 | defined: | 
 |  | 
 | =over 4 | 
 |  | 
 | =item "provider=base" | 
 |  | 
 | =back | 
 |  | 
 | 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. | 
 |  | 
 | =over 4 | 
 |  | 
 | =item "type=parameters" | 
 |  | 
 | =item "type=private" | 
 |  | 
 | =item "type=public" | 
 |  | 
 | =back | 
 |  | 
 | 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. | 
 |  | 
 | =over 4 | 
 |  | 
 | =item "format=der" | 
 |  | 
 | =item "format=pem" | 
 |  | 
 | =item "format=text" | 
 |  | 
 | =back | 
 |  | 
 | 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. | 
 |  | 
 | =head1 OPERATIONS AND ALGORITHMS | 
 |  | 
 | The OpenSSL base provider supports these operations and algorithms: | 
 |  | 
 | =head2 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. |
