.. 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.

\fIEVP_ciphername is used a placeholder for any of the described cipher functions, such as EVP_des_cbc.

"DESCRIPTION"
Header "DESCRIPTION" The \s-1DES\s0 encryption algorithm for \s-1EVP.\s0
"EVP_des_cbc(), EVP_des_ecb(), EVP_des_cfb(), EVP_des_cfb1(), EVP_des_cfb8(), EVP_des_cfb64(), EVP_des_ofb()" 4
Item "EVP_des_cbc(), EVP_des_ecb(), EVP_des_cfb(), EVP_des_cfb1(), EVP_des_cfb8(), EVP_des_cfb64(), EVP_des_ofb()" \s-1DES\s0 in \s-1CBC, ECB, CFB\s0 with 64-bit shift, \s-1CFB\s0 with 1-bit shift, \s-1CFB\s0 with 8-bit shift and \s-1OFB\s0 modes. .Sp None of these algorithms are provided by the OpenSSL default provider. To use them it is necessary to load either the OpenSSL legacy provider or another implementation.

"EVP_des_ede3_wrap()" 4
Item "EVP_des_ede3_wrap()" Triple-DES key wrap according to \s-1RFC 3217\s0 Section 3.
"NOTES"
Header "NOTES" Developers should be aware of the negative performance implications of calling these functions multiple times and should consider using \fBEVP_CIPHER_fetch\|(3) instead. See \*(L"Performance\*(R" in crypto\|(7) for further information.
"RETURN VALUES"
Header "RETURN VALUES" These functions return an \s-1EVP_CIPHER\s0 structure that contains the implementation of the symmetric cipher. See EVP_CIPHER_meth_new\|(3) for details of the \s-1EVP_CIPHER\s0 structure.
