It has associated private and public key formats compatible with RFC 8410.</p> <p>No additional parameters can be set during key generation.</p> <p>The peer public key must be set using EVP_PKEY_derive_set_peer() when performing key derivation.</p> <h1 id="NOTES">NOTES</h1> <p>A context for the <b>X25519</b> algorithm can be obtained by calling:</p> <pre><code> EVP_PKEY_CTX *pctx = EVP_PKEY_CTX_new_id(EVP_PKEY_X25519, NULL);</code></pre> <p>For the <b>X448</b> algorithm a context can be obtained by calling:</p> <pre><code> EVP_PKEY_CTX *pctx = EVP_PKEY_CTX_new_id(EVP_PKEY_X448, NULL);</code></pre> <p>X25519 or X448 private keys can be set directly using <a href="../man3/EVP_PKEY_new_raw_private_key.html">EVP_PKEY_new_raw_private_key(3)</a> or loaded from a PKCS#8 private key file using <a href="../man3/PEM_read_bio_PrivateKey.html">PEM_read_bio_PrivateKey(3)</a> (or similar function). Completely new keys can also be generated (see the example below). Setting a private key also sets the associated public key.</p> <p>X25519 or X448 public keys can be set directly using <a href="../man3/EVP_PKEY_new_raw_public_key.html">EVP_PKEY_new_raw_public_key(3)</a> or loaded from a SubjectPublicKeyInfo structure in a PEM file using <a href="../man3/PEM_read_bio_PUBKEY.html">PEM_read_bio_PUBKEY(3)</a> (or similar function).</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>This example generates an <b>X25519</b> private key and writes it to standard output in PEM format:</p> <pre><code> #include <openssl/evp.h> #include <openssl/pem.h> ...
