The key is sent to BIO <b>out</b> in human readable form. The parameter <b>indent</b> indicated how far the printout should be indented.</p> <p>The <b>pctx</b> parameter allows the print output to be finely tuned by using ASN1 printing options. If <b>pctx</b> is set to NULL then default values will be used.</p> <h1 id="NOTES">NOTES</h1> <p>Currently no public key algorithms include any options in the <b>pctx</b> parameter.</p> <p>If the key does not include all the components indicated by the function then only those contained in the key will be printed. For example passing a public key to EVP_PKEY_print_private() will only print the public components.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>These functions all return 1 for success and 0 or a negative value for failure. In particular a return value of -2 indicates the operation is not supported by the public key algorithm.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/EVP_PKEY_CTX_new.html">EVP_PKEY_CTX_new(3)</a>, <a href="../man3/EVP_PKEY_keygen.html">EVP_PKEY_keygen(3)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>These functions were added in OpenSSL 1.0.0.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2006-2017 The OpenSSL Project Authors.
