67 | * WARNINGS: | ||
68 | * | ||
69 | * - The data format used by DES_enc_write() and DES_enc_read() | ||
70 | * has a cryptographic weakness: When asked to write more | ||
71 | * than MAXWRITE bytes, DES_enc_write will split the data | ||
72 | * into several chunks that are all encrypted | ||
73 | * using the same IV. So don't use these functions unless you | ||
74 | * are sure you know what you do (in which case you might | ||
75 | * not want to use them anyway). | ||
76 | * | ||
77 | * - This code cannot handle non-blocking sockets. | ||
