<p>OSSL_PROVIDER-base - OpenSSL base provider</p>
<h1 id="DESCRIPTION">DESCRIPTION</h1>
<p>The OpenSSL base provider supplies the encoding for OpenSSL's asymmetric cryptography.</p>
<h2 id="Properties">Properties</h2>
<p>The implementations in this provider specifically have this property defined:</p>
<dl>
<dt id="provider-base">"provider=base"</dt>
<dd>
</dd>
</dl>
<p>It may be used in a property query string with fetching functions.</p>
<p>It isn't mandatory to query for this property, except to make sure to get implementations of this provider and none other.</p>
<dl>
<dt id="type-parameters">"type=parameters"</dt>
<dd>
</dd>
<dt id="type-private">"type=private"</dt>
<dd>
</dd>
<dt id="type-public">"type=public"</dt>
<dd>
</dd>
</dl>
<p>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.</p>
<dl>
<dt id="format-der">"format=der"</dt>
<dd>
</dd>
<dt id="format-pem">"format=pem"</dt>
<dd>
</dd>
<dt id="format-text">"format=text"</dt>
<dd>
</dd>
</dl>
<p>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.</p>
<h1 id="OPERATIONS-AND-ALGORITHMS">OPERATIONS AND ALGORITHMS</h1>
<p>The OpenSSL base provider supports these operations and algorithms:</p>
<h2 id="Asymmetric-Key-Encoder">Asymmetric Key Encoder</h2>
<p>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.</p>
