EVP_KEM-RSA

=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The B<RSA> keytype and its parameters are described in L<EVP_PKEY-RSA(7)>.
|
||
|
|
See L<EVP_PKEY_encapsulate(3)> and L<EVP_PKEY_decapsulate(3)> for more info.

|
The OpenSSL RSA Key Encapsulation Mechanism only currently supports the
|
||
|
|
following operation
|

=over 4
|
||
|
|
|
||
|
|
=item "RSASVE"
|
||
|
|
|
||
|
|
The encapsulate function simply generates a secret using random bytes and then
|
||
|
|
encrypts the secret using the RSA public key (with no padding).
|
||
|
|
The decapsulate function recovers the secret using the RSA private key.

|
||
|

|

This can be set using EVP_PKEY_CTX_set_kem_op().
