+- EVP_PKEY X25519, X448, ED25519 and ED448 keytype and algorithm support
+
+=head1 DESCRIPTION
+
+The B<X25519>, B<X448>, B<ED25519> and B<ED448> keytypes are
+implemented in OpenSSL's default provider.
+
+=head2 Common X25519, X448, ED25519 and ED448 parameters
+
+The following Import/Export types are available for the built-in X25519, X448,
+ED25519 and X448 algorithms:
+
+=over 4
+
+=item "pub" (B<OSSL_PKEY_PARAM_PUB_KEY>) <octet string>
+
+The public key value.
+
+=item "priv" (B<OSSL_PKEY_PARAM_PRIV_KEY>) <octet string>
+
+The private key value.

+=head1 EXAMPLES
+
+An B<EVP_PKEY> context can be obtained by calling:
+
+    EVP_PKEY_CTX *pctx =
+        EVP_PKEY_CTX_new_from_name(NULL, "X25519", NULL);
+
+    EVP_PKEY_CTX *pctx =
+        EVP_PKEY_CTX_new_from_name(NULL, "X448", NULL);
+
+    EVP_PKEY_CTX *pctx =
+        EVP_PKEY_CTX_new_from_name(NULL, "ED25519", NULL);
+
+    EVP_PKEY_CTX *pctx =
+        EVP_PKEY_CTX_new_from_name(NULL, "ED448", NULL);
+
+An B<ED25519> key can be generated like this:
+
+    EVP_PKEY *pkey = NULL;
+    EVP_PKEY_CTX *pctx =
+        EVP_PKEY_CTX_new_from_name(NULL, "ED25519", NULL);
+
+    EVP_PKEY_keygen_init(pctx);
+    EVP_PKEY_gen(pctx, &pkey);
+    EVP_PKEY_CTX_free(pctx);
+
+An B<X25519> key can be generated in a similar way:
+
+    EVP_PKEY *pkey = NULL;
+    EVP_PKEY_CTX *pctx =
+        EVP_PKEY_CTX_new_from_name(NULL, "X25519", NULL);
+
+    EVP_PKEY_keygen_init(pctx);
+    EVP_PKEY_gen(pctx, &pkey);
+    EVP_PKEY_CTX_free(pctx);
