=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The B<X25519>, B<X448>, B<ED25519> and B<ED448> keytypes are
|
||
|
|
implemented in OpenSSL's default and FIPS providers. These implementations
|
||
|
|
support the associated key, containing the public key I<pub> and the
|
||
|
|
private key I<priv>.
|
||
|
|
|
||
|
|
No additional parameters can be set during key generation.

|
|
=head2 Common X25519, X448, ED25519 and ED448 parameters
|
||
|
|
|
||
|
|
In addition to the common parameters that all keytypes should support (see
|
||
|
|
L<provider-keymgmt(7)/Common parameters>), the implementation of these keytypes
|
||
|
|
support the following.
|

|

=over 4
|
||
|
|
|
||
|
|
=item "group" (B<OSSL_PKEY_PARAM_GROUP_NAME>) <UTF8 string>
|
||
|
|
|
||
|
|
This is only supported by X25519 and X448. The group name must be "x25519" or
|
||
|
|
"x448" respectively for those algorithms. This is only present for consistency
|
||
|
|
with other key exchange algorithms and is typically not needed.
|
||
|
|
|
||
|
|
=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.
|
||
|
|
|
||
|
|
=item "encoded-pub-key" (B<OSSL_PKEY_PARAM_ENCODED_PUBLIC_KEY>) <octet string>
|
||
|
|
|
||
|
|
Used for getting and setting the encoding of a public key for the B<X25519> and
|
||
|
|
B<X448> key types. Public keys are expected be encoded in a format as defined by
|
||
|
|
RFC7748.

=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<X25519> key can be generated like this:
|
||
|
|
|
||
|
|
pkey = EVP_PKEY_Q_keygen(NULL, NULL, "X25519");
|
||
|
|
|
||
|
|
An B<X448>, B<ED25519>, or B<ED448> key can be generated likewise.
