NAME

6       EVP_KEM-RSA - EVP_KEM RSA keytype and algorithm support
7

DESCRIPTION

9       The RSA keytype and its parameters are described in EVP_PKEY-RSA(7).
10       See EVP_PKEY_encapsulate(3) and EVP_PKEY_decapsulate(3) for more info.

12   RSA KEM parameters
13       "operation" (OSSL_KEM_PARAM_OPERATION) <UTF8 string>
14           The OpenSSL RSA Key Encapsulation Mechanism only currently supports
15           the following operation
16
17           "RSASVE"
18               The encapsulate function simply generates a secret using random
19               bytes and then encrypts the secret using the RSA public key
20               (with no padding).  The decapsulate function recovers the
21               secret using the RSA private key.
22
23           This can be set using EVP_PKEY_CTX_set_kem_op().
