- * WARNINGS:
- *
- *  -  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).
- *
- *  -  This code cannot handle non-blocking sockets.
- *
- *  -  This function uses an internal state and thus cannot be
- *     used on multiple files.
