 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.
