This library contains a fast implementation of the DES encryption
@ -256,25 +251,6 @@ containing the length of the following encrypted data. The encrypted
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.
