.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
"NAME"
EVP_KEM-RSA \- EVP_KEM RSA keytype and algorithm support
"DESCRIPTION"
Header "DESCRIPTION" The \s-1RSA\s0 keytype and its parameters are described in \s-1EVP_PKEY-RSA\s0\|(7). See EVP_PKEY_encapsulate\|(3) and EVP_PKEY_decapsulate\|(3) for more info.
"\s-1RSA KEM\s0 parameters"
Subsection "RSA KEM parameters" Item "operation (OSSL_KEM_PARAM_OPERATION) <UTF8 string>" The OpenSSL \s-1RSA\s0 Key Encapsulation Mechanism only currently supports the following operation

Item "RSASVE" The encapsulate function simply generates a secret using random bytes and then encrypts the secret using the \s-1RSA\s0 public key (with no padding). The decapsulate function recovers the secret using the \s-1RSA\s0 private key.

.Sp This can be set using EVP_PKEY_CTX_set_kem_op().
