=pod =head1 NAME EVP_KEM-RSA - EVP_KEM RSA keytype and algorithm support =head1 DESCRIPTION The B keytype and its parameters are described in L. See L and L for more info. =head2 RSA KEM parameters =over 4 =item "operation" (B) 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. =back This can be set using EVP_PKEY_CTX_set_kem_op(). =back =head1 CONFORMING TO =over 4 =item SP800-56Br2 Section 7.2.1.2 RSASVE Generate Operation (RSASVE.GENERATE).
