NAME
EVP_KEM-RSA - EVP_KEM RSA keytype and algorithm support
DESCRIPTION
The RSA keytype and its parameters are described in EVP_PKEY-RSA(7).
See EVP_PKEY_encapsulate(3) and EVP_PKEY_decapsulate(3) for more info.
RSA KEM parameters
"operation" (OSSL_KEM_PARAM_OPERATION) <UTF8 string>
The OpenSSL RSA Key Encapsulation Mechanism only currently supports
the following operation
"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().
CONFORMING TO

Section 7.2.1.2 RSASVE Generate Operation (RSASVE.GENERATE).
Section 7.2.1.3 RSASVE Recovery Operation (RSASVE.RECOVER).
