-/**\r
- * Pure-PHP implementation of AES.\r
- *\r
- * Uses mcrypt, if available/possible, and an internal implementation, otherwise.\r
- *\r
- * PHP versions 4 and 5\r
- *\r
- * NOTE: Since AES.php is (for compatibility and phpseclib-historical reasons) virtually\r
- * just a wrapper to Rijndael.php you may consider using Rijndael.php instead of\r
- * to save one include_once().\r
- *\r
- * If {@link self::setKeyLength() setKeyLength()} isn't called, it'll be calculated from\r
- * {@link self::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's 136-bits\r
- * it'll be null-padded to 192-bits and 192 bits will be the key length until {@link self::setKey() setKey()}\r
- * is called, again, at which point, it'll be recalculated.\r
- *\r
- * Since Crypt_AES extends Crypt_Rijndael, some functions are available to be called that, in the context of AES, don't\r
- * make a whole lot of sense. {@link self::setBlockLength() setBlockLength()}, for instance. Calling that function,\r
- * however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one).\r
- *\r
- * Here's a short example of how to use this library:\r
- * <code>\r
- * <?php\r
- * include 'Crypt/AES.php';\r
- *\r
- * $aes = new Crypt_AES();\r
- *\r
- * $aes->setKey('abcdefghijklmnop');\r
- *\r
- * $size = 10 * 1024;\r
- * $plaintext = '';\r
- * for ($i = 0; $i < $size; $i++) {\r
- * $plaintext.= 'a';\r
- * }\r
- *\r
- * echo $aes->decrypt($aes->encrypt($plaintext));\r
- * ?>\r

-/**\r
- * Pure-PHP implementations of keyed-hash message authentication codes (HMACs) and various cryptographic hashing functions.\r
- *\r
- * Uses hash() or mhash() if available and an internal implementation, otherwise. Currently supports the following:\r
- *\r
- * md2, md5, md5-96, sha1, sha1-96, sha256, sha256-96, sha384, and sha512, sha512-96\r
- *\r
- * If {@link self::setKey() setKey()} is called, {@link self::hash() hash()} will return the HMAC as opposed to\r
- * the hash. If no valid algorithm is provided, sha1 will be used.\r
- *\r
- * PHP versions 4 and 5\r
- *\r
- * {@internal The variable names are the same as those in\r
- * {@link http://tools.ietf.org/html/rfc2104#section-2 RFC2104}.}}\r
- *\r
- * Here's a short example of how to use this library:\r
- * <code>\r
- * <?php\r
- * include 'Crypt/Hash.php';\r
- *\r
- * $hash = new Crypt_Hash('sha1');\r
- *\r
- * $hash->setKey('abcdefg');\r
- *\r
- * echo base64_encode($hash->hash('abcdefg'));\r

- * Pure-PHP implementation of Rijndael.\r
- *\r
- * Uses mcrypt, if available/possible, and an internal implementation, otherwise.\r
- *\r
- * PHP versions 4 and 5\r
- *\r
- * If {@link self::setBlockLength() setBlockLength()} isn't called, it'll be assumed to be 128 bits. If\r
- * {@link self::setKeyLength() setKeyLength()} isn't called, it'll be calculated from\r
- * {@link self::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's\r
- * 136-bits it'll be null-padded to 192-bits and 192 bits will be the key length until\r
- * {@link self::setKey() setKey()} is called, again, at which point, it'll be recalculated.\r
- *\r
- * Not all Rijndael implementations may support 160-bits or 224-bits as the block length / key length. mcrypt, for example,\r
- * does not. AES, itself, only supports block lengths of 128 and key lengths of 128, 192, and 256.\r
- * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=10 Rijndael-ammended.pdf#page=10} defines the\r
- * algorithm for block lengths of 192 and 256 but not for block lengths / key lengths of 160 and 224. Indeed, 160 and 224\r
- * are first defined as valid key / block lengths in\r
- * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=44 Rijndael-ammended.pdf#page=44}:\r
- * Extensions: Other block and Cipher Key lengths.\r
- * Note: Use of 160/224-bit Keys must be explicitly set by setKeyLength(160) respectively setKeyLength(224).\r
- *\r
- * {@internal The variable names are the same as those in\r

- * $plaintext = '';\r
- * for ($i = 0; $i < $size; $i++) {\r

- * Pure-PHP arbitrary precision integer arithmetic library.\r
- *\r
- * Supports base-2, base-10, base-16, and base-256 numbers. Uses the GMP or BCMath extensions, if available,\r
- * and an internal implementation, otherwise.\r

- * {@internal (all DocBlock comments regarding implementation - such as the one that follows - refer to the\r

- *\r
- * Math_BigInteger uses base-2**26 to perform operations such as multiplication and division and\r
- * base-2**52 (ie. two base 2**26 digits) to perform addition and subtraction. Because the largest possible\r
- * value when multiplying two base-2**26 numbers together is a base-2**52 number, double precision floating\r
- * point numbers - numbers that should be supported on most hardware and whose significand is 53 bits - are\r
- * used. As a consequence, bitwise operators such as >> and << cannot be used, nor can the modulo operator %,\r
- * which only supports integers. Although this fact will slow this library down, the fact that such a high\r
- * base is being used should more than compensate.\r
- *\r
- * Numbers are stored in {@link http://en.wikipedia.org/wiki/Endianness little endian} format. ie.\r
- * (new Math_BigInteger(pow(2, 26)))->value = array(0, 1)\r

- numbers it SHOULD send '3'"\r

- server MAY send a status response describing the failure, but MUST then close the channel without\r
- processing any further requests."\r

- So what do you do if you have a client whose initial SSH_FXP_INIT packet says it implements v3 and\r
- a server whose initial SSH_FXP_VERSION reply says it implements v4 and only v4? If it only implements\r
- v4, the "versions" extension is likely not going to have been sent so version re-negotiation as discussed\r
- in draft-ietf-secsh-filexfer-13 would be quite impossible. As such, what Net_SFTP would do is close the\r

- * Uploads a file to the SFTP server.\r

- * long, containing 'filename.ext' as its contents.\r
- *\r
- * Setting $mode to NET_SFTP_LOCAL_FILE will change the above behavior. With NET_SFTP_LOCAL_FILE, $remote_file will\r
- * contain as many bytes as filename.ext does on your local filesystem. If your filename.ext is 1MB then that is how\r
- * large $remote_file will be, as well.\r
- *\r
- * If $data is a resource then it'll be used as a resource instead.\r
- *\r
- *\r
- * Setting $mode to NET_SFTP_CALLBACK will use $data as callback function, which gets only one parameter -- number\r
- * of bytes to return, and returns a string if there is some data or null if there is no more data\r
- *\r
- * Currently, only binary mode is supported. As such, if the line endings need to be adjusted, you will need to take\r
- * care of that, yourself.\r
- *\r
- * $mode can take an additional two parameters - NET_SFTP_RESUME and NET_SFTP_RESUME_START. These are bitwise AND'd with\r
- * $mode. So if you want to resume upload of a 300mb file on the local file system you'd set $mode to the following:\r
- *\r
- * NET_SFTP_LOCAL_FILE | NET_SFTP_RESUME\r
- *\r
- * If you wanted to simply append the full contents of a local file to the full contents of a remote file you'd replace\r
- * NET_SFTP_RESUME with NET_SFTP_RESUME_START.\r
- *\r
- * If $mode & (NET_SFTP_RESUME | NET_SFTP_RESUME_START) then NET_SFTP_RESUME_START will be assumed.\r
- *\r
- * $start and $local_start give you more fine grained control over this process and take precident over NET_SFTP_RESUME\r
- * when they're non-negative. ie. $start could let you write at the end of a file (like NET_SFTP_RESUME) or in the middle\r
- * of one. $local_start could let you start your reading from the end of a file (like NET_SFTP_RESUME_START) or in the\r
- * middle of one.\r
