347 | * echo $des->encrypt(substr($plaintext, 8, 8));
348 | *
349 | *
350 | * echo $des->encrypt($plaintext);
351 | *
352 | *
353 | * The solution is to enable the continuous buffer. Although this will resolve the above discrepancy, it creates
354 | * another, as demonstrated with the following:
355 | *
356 | *
357 | * $des->encrypt(substr($plaintext, 0, 8));
358 | * echo $des->decrypt($des->encrypt(substr($plaintext, 8, 8)));
359 | *
360 | *
361 | * echo $des->decrypt($des->encrypt(substr($plaintext, 8, 8)));
362 | *
363 | *
364 | * With the continuous buffer disabled, these would yield the same output. With it enabled, they yield different
365 | * outputs. The reason is due to the fact that the initialization vector's change after every encryption /
366 | * decryption round when the continuous buffer is enabled. When it's disabled, they remain constant.
367 | *
368 | * Put another way, when the continuous buffer is enabled, the state of the \phpseclib\Crypt\DES() object changes after each
369 | * encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that
370 | * continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them),
371 | * however, they are also less intuitive and more likely to cause you problems.
