EVP_KEM-RSA - EVP_KEM RSA keytype and algorithm support
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.
- "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().
- SP800-56Br2
- Section 7.2.1.2 RSASVE Generate Operation (RSASVE.GENERATE). Section
7.2.1.3 RSASVE Recovery Operation (RSASVE.RECOVER).
