/**
|
| 5 |
+
* Pure-PHP implementation of AES.
|
| 6 |
+
*
|
| 7 |
+
* Uses mcrypt, if available, and an internal implementation, otherwise.
|
| 8 |
+
*
|
| 9 |
+
* PHP versions 4 and 5
|
| 10 |
+
*
|
| 11 |
+
* If {@link Crypt_AES::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
|
| 12 |
+
* {@link Crypt_AES::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's 136-bits
|
| 13 |
+
* it'll be null-padded to 160-bits and 160 bits will be the key length until {@link Crypt_Rijndael::setKey() setKey()}
|
| 14 |
+
* is called, again, at which point, it'll be recalculated.
|
| 15 |
+
*
|
| 16 |
+
* Since Crypt_AES extends Crypt_Rijndael, some functions are available to be called that, in the context of AES, don't
|
| 17 |
+
* make a whole lot of sense. {@link Crypt_AES::setBlockLength() setBlockLength()}, for instance. Calling that function,
|
| 18 |
+
* however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one).
|
| 19 |
+
*
|
| 20 |
+
* Here's a short example of how to use this library:
|
| 21 |
+
* <code>
|
| 22 |
+
* <?php
|
| 23 |
+
* include('Crypt/AES.php');
|
| 24 |
+
*
|
| 25 |
+
* $aes = new Crypt_AES();
|
| 26 |
+
*
|
| 27 |
+
* $aes->setKey('abcdefghijklmnop');
|
| 28 |
+
*
|
| 29 |
+
* $size = 10 * 1024;
|
| 30 |
+
* $plaintext = '';
|
| 31 |
+
* for ($i = 0; $i < $size; $i++) {
|
| 32 |
+
* $plaintext.= 'a';
|
| 33 |
+
* }
|
| 34 |
+
*
|
| 35 |
+
* echo $aes->decrypt($aes->encrypt($plaintext));
|
| 36 |
+
* ?>
|
| 37 |
+
* </code>

+
*
|
| 9 |
+
* PHP versions 4 and 5
|
| 10 |

* Here's a short example of how to use this library:
|
| 18 |
+
* <code>

|
| 23 |
+
*
|
| 24 |
+
* $des->setKey('abcdefgh');
|
| 25 |
+
*
|
| 26 |
+
* $size = 10 * 1024;
|
| 27 |
+
* $plaintext = '';
|
| 28 |
+
* for ($i = 0; $i < $size; $i++) {
|
| 29 |
+
* $plaintext.= 'a';
|
| 30 |
+
* }
|
| 31 |
+
*
|
| 32 |

* Treat consecutive "packets" as if they are a continuous buffer.

|

* Say you have a 16-byte plaintext $plaintext. Using the default behavior, the two following code snippets
|
| 1347 |
+
* will yield different outputs:
|
| 1348 |
+
*
|
| 1349 |
+
* <code>
|
| 1350 |
+
* echo $des->encrypt(substr($plaintext, 0, 8));
|
| 1351 |
+
* echo $des->encrypt(substr($plaintext, 8, 8));
|
| 1352 |
+
* </code>
|
| 1353 |
+
* <code>
|
| 1354 |
+
* echo $des->encrypt($plaintext);
|
| 1355 |
+
* </code>
|
| 1356 |
+
*
|
| 1357 |
+
* The solution is to enable the continuous buffer. Although this will resolve the above discrepancy, it creates
|
| 1358 |
+
* another, as demonstrated with the following:
|
| 1359 |
+
*
|
| 1360 |
+
* <code>
|
| 1361 |
+
* $des->encrypt(substr($plaintext, 0, 8));
|
| 1362 |
+
* echo $des->decrypt($des->encrypt(substr($plaintext, 8, 8)));
|
| 1363 |
+
* </code>
|
| 1364 |
+
* <code>
|
| 1365 |
+
* echo $des->decrypt($des->encrypt(substr($plaintext, 8, 8)));
|
| 1366 |
+
* </code>
|
| 1367 |
+
*
|
| 1368 |
+
* With the continuous buffer disabled, these would yield the same output. With it enabled, they yield different
|
| 1369 |
+
* outputs. The reason is due to the fact that the initialization vector's change after every encryption /
|
| 1370 |
+
* decryption round when the continuous buffer is enabled. When it's disabled, they remain constant.
|
| 1371 |
+
*
|
| 1372 |
+
* Put another way, when the continuous buffer is enabled, the state of the Crypt_DES() object changes after each
|
| 1373 |
+
* encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that
|
| 1374 |
+
* continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them),
|
| 1375 |

* Pure-PHP implementations of keyed-hash message authentication codes (HMACs) and various cryptographic hashing functions.
|
| 6 |

*
|
| 7 |
+
* Uses hash() or mhash() if available and an internal implementation, otherwise. Currently supports the following:
|
| 8 |
+
*
|
| 9 |
+
* md2, md5, md5-96, sha1, sha1-96, sha256, sha384, and sha512

*
|
| 11 |
+
* If {@link Crypt_Hash::setKey() setKey()} is called, {@link Crypt_Hash::hash() hash()} will return the HMAC as opposed to
|
| 12 |
+
* the hash. If no valid algorithm is provided, sha1 will be used.

|
| 8 |
+
*
|

* PHP versions 4 and 5
|
| 10 |
+
*
|
| 11 |

* - {@link http://www.mozilla.org/projects/security/pki/nss/draft-kaukonen-cipher-arcfour-03.txt ARCFOUR Algorithm}

|
| 15 |

|
| 16 |
+
* RC4 is also known as ARCFOUR or ARC4. The reason is elaborated upon at Wikipedia. This class is named RC4 and not
|
| 17 |
+
* ARCFOUR or ARC4 because RC4 is how it is referred to in the SSH1 specification.
|
| 18 |
+
*
|
| 19 |
+
* Here's a short example of how to use this library:
|
| 20 |
+
* <code>
|
| 21 |
+
* <?php
|
| 22 |
+
* include('Crypt/RC4.php');
|
| 23 |
+
*
|
| 24 |
+
* $rc4 = new Crypt_RC4();
|
| 25 |
+
*
|
| 26 |
+
* $rc4->setKey('abcdefgh');
|
| 27 |
+
*
|
| 28 |
+
* $size = 10 * 1024;
|
| 29 |
+
* $plaintext = '';
|
| 30 |
+
* for ($i = 0; $i < $size; $i++) {
|
| 31 |
+
* $plaintext.= 'a';
|
| 32 |
+
* }
|
| 33 |
+
*
|
| 34 |
+
* echo $rc4->decrypt($rc4->encrypt($plaintext));
|
| 35 |
+
* ?>

*
|
| 427 |
+
* With the continuous buffer disabled, these would yield the same output. With it enabled, they yield different
|
| 428 |
+
* outputs. The reason is due to the fact that the initialization vector's change after every encryption /
|
| 429 |
+
* decryption round when the continuous buffer is enabled. When it's disabled, they remain constant.

/**
|
| 5 |
+
* Pure-PHP implementation of Rijndael.
|
| 6 |
+
*
|
| 7 |
+
* Does not use mcrypt, even when available, for reasons that are explained below.
|
| 8 |
+
*
|
| 9 |
+
* PHP versions 4 and 5
|
| 10 |
+
*
|
| 11 |
+
* If {@link Crypt_Rijndael::setBlockLength() setBlockLength()} isn't called, it'll be assumed to be 128 bits. If
|
| 12 |
+
* {@link Crypt_Rijndael::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
|
| 13 |
+
* {@link Crypt_Rijndael::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's
|
| 14 |
+
* 136-bits it'll be null-padded to 160-bits and 160 bits will be the key length until
|
| 15 |
+
* {@link Crypt_Rijndael::setKey() setKey()} is called, again, at which point, it'll be recalculated.
|
| 16 |
+
*
|
| 17 |
+
* Not all Rijndael implementations may support 160-bits or 224-bits as the block length / key length. mcrypt, for example,
|
| 18 |
+
* does not. AES, itself, only supports block lengths of 128 and key lengths of 128, 192, and 256.
|
| 19 |
+
* {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=10 Rijndael-ammended.pdf#page=10} defines the
|
| 20 |
+
* algorithm for block lengths of 192 and 256 but not for block lengths / key lengths of 160 and 224. Indeed, 160 and 224
|
| 21 |
+
* are first defined as valid key / block lengths in
|
| 22 |
+
* {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=44 Rijndael-ammended.pdf#page=44}:
|
| 23 |
+
* Extensions: Other block and Cipher Key lengths.
|
| 24 |
+
*
|
| 25 |
+
* {@internal The variable names are the same as those in
|
| 26 |
+
* {@link http://www.csrc.nist.gov/publications/fips/fips197/fips-197.pdf#page=10 fips-197.pdf#page=10}.}}
|
| 27 |
+
*
|
| 28 |
+
* Here's a short example of how to use this library:
|
| 29 |
+
* <code>
|
| 30 |
+
* <?php
|
| 31 |
+
* include('Crypt/Rijndael.php');
|
| 32 |
+
*
|
| 33 |
+
* $rijndael = new Crypt_Rijndael();
|
| 34 |
+
*
|
| 35 |
+
* $rijndael->setKey('abcdefghijklmnop');
|
| 36 |
+
*
|
| 37 |
+
* $size = 10 * 1024;
|
| 38 |
+
* $plaintext = '';
|
| 39 |
+
* for ($i = 0; $i < $size; $i++) {
|
| 40 |
+
* $plaintext.= 'a';
|
| 41 |
+
* }
|
| 42 |
+
*
|
| 43 |
+
* echo $rijndael->decrypt($rijndael->encrypt($plaintext));
|
| 44 |
+
* ?>

* Treat consecutive "packets" as if they are a continuous buffer.
|

*
|
| 1505 |
+
* Say you have a 32-byte plaintext $plaintext. Using the default behavior, the two following code snippets
|
| 1506 |
+
* will yield different outputs:
|
| 1507 |
+
*
|
| 1508 |
+
* <code>
|
| 1509 |
+
* echo $rijndael->encrypt(substr($plaintext, 0, 16));
|
| 1510 |
+
* echo $rijndael->encrypt(substr($plaintext, 16, 16));
|
| 1511 |
+
* </code>
|
| 1512 |
+
* <code>
|
| 1513 |
+
* echo $rijndael->encrypt($plaintext);
|
| 1514 |
+
* </code>
|
| 1515 |
+
*
|
| 1516 |
+
* The solution is to enable the continuous buffer. Although this will resolve the above discrepancy, it creates
|
| 1517 |
+
* another, as demonstrated with the following:
|
| 1518 |
+
*
|
| 1519 |
+
* <code>
|
| 1520 |
+
* $rijndael->encrypt(substr($plaintext, 0, 16));
|
| 1521 |
+
* echo $rijndael->decrypt($des->encrypt(substr($plaintext, 16, 16)));
|
| 1522 |
+
* </code>
|
| 1523 |
+
* <code>
|
| 1524 |
+
* echo $rijndael->decrypt($des->encrypt(substr($plaintext, 16, 16)));
|
| 1525 |
+
* </code>
|
| 1526 |
+
*
|
| 1527 |
+
* With the continuous buffer disabled, these would yield the same output. With it enabled, they yield different
|
| 1528 |
+
* outputs. The reason is due to the fact that the initialization vector's change after every encryption /
|
| 1529 |
+
* decryption round when the continuous buffer is enabled. When it's disabled, they remain constant.
|
| 1530 |
+
*
|
| 1531 |
+
* Put another way, when the continuous buffer is enabled, the state of the Crypt_Rijndael() object changes after each
|
| 1532 |
+
* encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that
|
| 1533 |
+
* continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them),
|
| 1534 |
+
* however, they are also less intuitive and more likely to cause you problems.

* Treat consecutive "packets" as if they are a continuous buffer.
|
| 770 |
+
*
|
| 771 |
+
* Say you have a 16-byte plaintext $plaintext. Using the default behavior, the two following code snippets
|
| 772 |
+
* will yield different outputs:
|
| 773 |
+
*
|
| 774 |
+
* <code>
|
| 775 |
+
* echo $des->encrypt(substr($plaintext, 0, 8));
|
| 776 |
+
* echo $des->encrypt(substr($plaintext, 8, 8));
|
| 777 |
+
* </code>
|
| 778 |
+
* <code>
|
| 779 |
+
* echo $des->encrypt($plaintext);
|
| 780 |
+
* </code>
|
| 781 |
+
*
|
| 782 |
+
* The solution is to enable the continuous buffer. Although this will resolve the above discrepancy, it creates
|
| 783 |
+
* another, as demonstrated with the following:
|
| 784 |
+
*
|
| 785 |
+
* <code>
|
| 786 |
+
* $des->encrypt(substr($plaintext, 0, 8));
|
| 787 |
+
* echo $des->decrypt($des->encrypt(substr($plaintext, 8, 8)));
|
| 788 |
+
* </code>
|
| 789 |
+
* <code>
|
| 790 |
+
* echo $des->decrypt($des->encrypt(substr($plaintext, 8, 8)));
|
| 791 |
+
* </code>
|
| 792 |
+
*
|
| 793 |
+
* With the continuous buffer disabled, these would yield the same output. With it enabled, they yield different
|
| 794 |
+
* outputs. The reason is due to the fact that the initialization vector's change after every encryption /
|
| 795 |
+
* decryption round when the continuous buffer is enabled. When it's disabled, they remain constant.
|
| 796 |
+
*
|
| 797 |
+
* Put another way, when the continuous buffer is enabled, the state of the Crypt_DES() object changes after each
|
| 798 |
+
* encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that
|
| 799 |
+
* continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them),
|
| 800 |
+
* however, they are also less intuitive and more likely to cause you problems.
|
| 801 |

* Pure-PHP X.509 Parser
|
| 6 |
+
*
|
| 7 |
+
* PHP versions 4 and 5
|
| 8 |
+
*
|
| 9 |
+
* Encode and decode X.509 certificates.
|
| 10 |
+
*
|
| 11 |
+
* The extensions are from {@link http://tools.ietf.org/html/rfc5280 RFC5280} and
|
| 12 |
+
* {@link http://web.archive.org/web/19961027104704/http://www3.netscape.com/eng/security/cert-exts.html Netscape Certificate Extensions}.
|
| 13 |
+
*
|
| 14 |
+
* Note that loading an X.509 certificate and resaving it may invalidate the signature. The reason being that the signature is based on a
|
| 15 |
+
* portion of the certificate that contains optional parameters with default values. ie. if the parameter isn't there the default value is
|
| 16 |
+
* used. Problem is, if the parameter is there and it just so happens to have the default value there are two ways that that parameter can
|
| 17 |
+
* be encoded. It can be encoded explicitly or left out all together. This would effect the signature value and thus may invalidate the
|
| 18 |
+
* the certificate all together unless the certificate is re-signed.

/**
|
| 5 |
+
* Pure-PHP arbitrary precision integer arithmetic library.
|
| 6 |
+
*
|
| 7 |
+
* Supports base-2, base-10, base-16, and base-256 numbers. Uses the GMP or BCMath extensions, if available,
|
| 8 |
+
* and an internal implementation, otherwise.
|
| 9 |
+
*
|
| 10 |
+
* PHP versions 4 and 5
|
| 11 |
+
*
|
| 12 |
+
* {@internal (all DocBlock comments regarding implementation - such as the one that follows - refer to the
|
| 13 |
+
* {@link MATH_BIGINTEGER_MODE_INTERNAL MATH_BIGINTEGER_MODE_INTERNAL} mode)
|
| 14 |
+
*
|
| 15 |
+
* Math_BigInteger uses base-2**26 to perform operations such as multiplication and division and
|
| 16 |
+
* base-2**52 (ie. two base 2**26 digits) to perform addition and subtraction. Because the largest possible
|
| 17 |
+
* value when multiplying two base-2**26 numbers together is a base-2**52 number, double precision floating
|
| 18 |
+
* point numbers - numbers that should be supported on most hardware and whose significand is 53 bits - are
|
| 19 |
+
* used. As a consequence, bitwise operators such as >> and << cannot be used, nor can the modulo operator %,
|
| 20 |
+
* which only supports integers. Although this fact will slow this library down, the fact that such a high
|
| 21 |
+
* base is being used should more than compensate.
|
| 22 |
+
*
|
| 23 |
+
* When PHP version 6 is officially released, we'll be able to use 64-bit integers. This should, once again,
|
| 24 |
+
* allow bitwise operators, and will increase the maximum possible base to 2**31 (or 2**62 for addition /
|
| 25 |
+
* subtraction).
|
| 26 |
+
*
|
| 27 |
+
* Numbers are stored in {@link http://en.wikipedia.org/wiki/Endianness little endian} format. ie.
|
| 28 |
+
* (new Math_BigInteger(pow(2, 26)))->value = array(0, 1)
|
| 29 |
+
*
|
| 30 |
+
* Useful resources are as follows:
|
| 31 |
+
*

* - {@link http://www.cacr.math.uwaterloo.ca/hac/about/chap14.pdf Handbook of Applied Cryptography (HAC)}

|
| 35 |
+
*
|
| 36 |
+
* Here's an example of how to use this library:
|
| 37 |
+
* <code>
|
| 38 |
+
* <?php
|
| 39 |
+
* include('Math/BigInteger.php');
|
| 40 |
+
*
|
| 41 |
+
* $a = new Math_BigInteger(2);
|
| 42 |
+
* $b = new Math_BigInteger(3);
|
| 43 |
+
*
|
| 44 |
+
* $c = $a->add($b);
|
| 45 |
+
*
|
| 46 |
+
* echo $c->toString(); // outputs 5
|
| 47 |
+
* ?>

* @internal The most naive approach to modular exponentiation has very unreasonable requirements, and
|
| 1594 |
+
* and although the approach involving repeated squaring does vastly better, it, too, is impractical
|
| 1595 |
+
* for our purposes. The reason being that division - by far the most complicated and time-consuming
|
| 1596 |
+
* of the basic operations (eg. +,-,*,/) - occurs multiple times within it.
|
| 1597 |
+
*
|
| 1598 |
+
* Modular reductions resolve this issue. Although an individual modular reduction takes more time
|
| 1599 |
+
* then an individual division, when performed in succession (with the same modulo), they're a lot faster.
|
| 1600 |
+
*
|
| 1601 |
+
* The two most commonly used modular reductions are Barrett and Montgomery reduction. Montgomery reduction,
|
| 1602 |
+
* although faster, only works when the gcd of the modulo and of the base being used is 1. In RSA, when the
|
| 1603 |
+
* base is a power of two, the modulo - a product of two primes - is always going to have a gcd of 1 (because
|
| 1604 |
+
* the product of two odd numbers is odd), but what about when RSA isn't used?
|
| 1605 |
+
*
|
| 1606 |
+
* In contrast, Barrett reduction has no such constraint. As such, some bigint implementations perform a
|
| 1607 |
+
* Barrett reduction after every operation in the modpow function. Others perform Barrett reductions when the
|
| 1608 |
+
* modulo is even and Montgomery reductions when the modulo is odd. BigInteger.java's modPow method, however,
|
| 1609 |
+
* uses a trick involving the Chinese Remainder Theorem to factor the even modulo into two numbers - one odd and
|
| 1610 |
+
* the other, a power of two - and recombine them, later. This is the method that this modPow function uses.

|
| 1953 |
+
* so as not to require negative numbers (initially, this script didn't support negative numbers).
|
| 1954 |
+
*
|
| 1955 |
+
* Employs "folding", as described at
|
| 1956 |
+
* {@link http://www.cosic.esat.kuleuven.be/publications/thesis-149.pdf#page=66 thesis-149.pdf#page=66}. To quote from
|
| 1957 |
+
* it, "the idea [behind folding] is to find a value x' such that x (mod m) = x' (mod m), with x' being smaller than x."
|
| 1958 |
+
*
|
| 1959 |
+
* Unfortunately, the "Barrett Reduction with Folding" algorithm described in thesis-149.pdf is not, as written, all that
|
| 1960 |
+
* usable on account of (1) its not using reasonable radix points as discussed in
|
| 1961 |
+
* {@link http://math.libtomcrypt.com/files/tommath.pdf#page=162 MPM 6.2.2} and (2) the fact that, even with reasonable
|
| 1962 |
+
* radix points, it only works when there are an even number of digits in the denominator. The reason for (2) is that
|
| 1963 |
+
* (x >> 1) + (x >> 1) != x / 2 + x / 2. If x is even, they're the same, but if x is odd, they're not. See the in-line
|
| 1964 |
+
* comments for details.

* As for why we do all the bitmasking... strange things can happen when converting from floats to ints. For
|
| 2339 |
+
* instance, on some computers, var_dump((int) -4294967297) yields int(-1) and on others, it yields
|
| 2340 |
+
* int(-2147483648). To avoid problems stemming from this, we use bitmasks to guarantee that ints aren't
|
| 2341 |
+
* auto-converted to floats. The outermost bitmask is present because without it, there's no guarantee that
|
| 2342 |
+
* the "residue" returned would be the so-called "common residue". We use fmod, in the last step, because the
|
| 2343 |
+
* maximum possible $x is 26 bits and the maximum $result is 16 bits. Thus, we have to be able to handle up to
|
| 2344 |
+
* 40 bits, which only 64-bit floating points will support.

| 6 |
+
*
|
| 7 |
+
* PHP versions 4 and 5
|
| 8 |
+
*
|
| 9 |
+
* Currently only supports SFTPv2 and v3, which, according to wikipedia.org, "is the most widely used version,
|
| 10 |
+
* implemented by the popular OpenSSH SFTP server". If you want SFTPv4/5/6 support, provide me with access
|
| 11 |
+
* to an SFTPv4/5/6 server.
|
| 12 |
+
*
|
| 13 |
+
* The API for this library is modeled after the API from PHP's {@link http://php.net/book.ftp FTP extension}.
|
| 14 |
+
*
|
| 15 |
+
* Here's a short example of how to use this library:
|
| 16 |
+
* <code>
|
| 17 |
+
* <?php
|
| 18 |
+
* include('Net/SFTP.php');
|
| 19 |
+
*
|
| 20 |
+
* $sftp = new Net_SFTP('www.domain.tld');
|
| 21 |
+
* if (!$sftp->login('username', 'password')) {
|
| 22 |
+
* exit('Login Failed');
|
| 23 |
+
* }
|
| 24 |
+
*
|
| 25 |
+
* echo $sftp->pwd() . "\r\n";
|
| 26 |
+
* $sftp->put('filename.ext', 'hello, world!');
|
| 27 |
+
* print_r($sftp->nlist());
|
| 28 |
+
* ?>
|
| 29 |
+
* </code>

A Note on SFTPv4/5/6 support:
|
| 474 |
+
<http://tools.ietf.org/html/draft-ietf-secsh-filexfer-13#section-5.1> states the following:
|
| 475 |
+
|
| 476 |
+
"If the client wishes to interoperate with servers that support noncontiguous version
|
| 477 |
+
numbers it SHOULD send '3'"
|
| 478 |
+
|
| 479 |
+
Given that the server only sends its version number after the client has already done so, the above
|
| 480 |
+
seems to be suggesting that v3 should be the default version. This makes sense given that v3 is the
|
| 481 |
+
most popular.
|
| 482 |
+
|
| 483 |
+
<http://tools.ietf.org/html/draft-ietf-secsh-filexfer-13#section-5.5> states the following;
|
| 484 |
+
|
| 485 |
+
"If the server did not send the "versions" extension, or the version-from-list was not included, the
|
| 486 |
+
server MAY send a status response describing the failure, but MUST then close the channel without
|
| 487 |
+
processing any further requests."
|
| 488 |
+
|
| 489 |
+
So what do you do if you have a client whose initial SSH_FXP_INIT packet says it implements v3 and
|
| 490 |
+
a server whose initial SSH_FXP_VERSION reply says it implements v4 and only v4? If it only implements
|
| 491 |
+
v4, the "versions" extension is likely not going to have been sent so version re-negotiation as discussed
|
| 492 |
+
in draft-ietf-secsh-filexfer-13 would be quite impossible. As such, what Net_SFTP would do is close the
|
| 493 |
+
channel and reopen it with a new and updated SSH_FXP_INIT packet.
