=head1 DESCRIPTION
This library contains a fast implementation of the DES encryption
DES_set_odd_parity() sets the parity of the passed I<key> to odd.
DES_is_weak_key() returns 1 if the passed key is a weak key, 0 if it
-is ok.
+is ok.
The following routines mostly operate on an input and output stream of
I<DES_cblock>s.
data then follows, padded with random data out to a multiple of 8
bytes.
-DES_enc_read() is used to read I<len> bytes from file descriptor
-I<fd> into buffer I<buf>. The data being read from I<fd> is assumed to
-have come from DES_enc_write() and is decrypted using I<sched> for
-the key schedule and I<iv> for the initial vector.
-
-B<Warning:> The data format used by DES_enc_write() and DES_enc_read()
-has a cryptographic weakness: When asked to write more than MAXWRITE
-bytes, DES_enc_write() will split the data into several chunks that
-are all encrypted using the same IV. So don't use these functions
-unless you are sure you know what you do (in which case you might not
-want to use them anyway). They cannot handle non-blocking sockets.
-DES_enc_read() uses an internal state and thus cannot be used on
-multiple files.
-
-I<DES_rw_mode> is used to specify the encryption mode to use with
-DES_enc_read() and DES_end_write(). If set to I<DES_PCBC_MODE> (the
-default), DES_pcbc_encrypt is used. If set to I<DES_CBC_MODE>
-DES_cbc_encrypt is used.
-
=head1 BUGS
DES_3cbc_encrypt() is flawed and must not be used in applications.
Single-key DES is insecure due to its short key size. ECB mode is
not suitable for most applications; see L<des_modes(7)>.
