  14 =head1 DESCRIPTION
  15
  16 The DES-X encryption algorithm for EVP.
  17
  18 All modes below use a key length of 128 bits and acts on blocks of 128-bits.

  23
  24 The DES-X algorithm in CBC mode.
  25
  26 This algorithm is not provided by the OpenSSL default provider.
  27 To use it is necessary to load either the OpenSSL legacy provider or another
  28 implementation.

  32 Developers should be aware of the negative performance implications of
  33 calling this function multiple times and should consider using
  34 L<EVP_CIPHER_fetch(3)> with L<EVP_CIPHER-DES(7)> instead.
  35 See L<crypto(7)/Performance> for further information.
  36
  37 =head1 RETURN VALUES
  38
  39 These functions return an B<EVP_CIPHER> structure that contains the
  40 implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for
  41 details of the B<EVP_CIPHER> structure.
