- * 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. |
