Member Function Documentation

◆ setBlockLength()

phpseclib\Crypt\AES::setBlockLength ( $length )

Dummy function.

Since extends , this function is, technically, available, but it doesn't do anything.

See also: ::setBlockLength() User interface

Parameters

int $length

Definition at line 72 of file AES.php.

     {
         return;
     }

◆ setKey()

phpseclib\Crypt\AES::setKey ( $key )

Sets the key.

Rijndael supports five different key lengths, AES only supports three.

See also: :setKey(); setKeyLength() User interface

Parameters

string $key

Definition at line 109 of file AES.php.

References phpseclib\Crypt\Base\$key, and phpseclib\Crypt\Base\_setEngine().

     {
         parent::setKey($key);
 
         if (!$this->explicit_key_length) {
             $length = strlen($key);
             switch (true) {
                 case $length <= 16:
                     $this->key_length = 16;
                     break;
                 case $length <= 24:
                     $this->key_length = 24;
                     break;
                 default:
                     $this->key_length = 32;
             }
             $this->_setEngine();
         }
     }

Here is the call graph for this function:

◆ setKeyLength()

phpseclib\Crypt\AES::setKeyLength ( $length )

Sets the key length.

Valid key lengths are 128, 192, and 256. If the length is less than 128, it will be rounded up to

If the length is greater than 128 and invalid, it will be rounded down to the closest valid amount.

Parameters

int $length

Definition at line 87 of file AES.php.

     {
         switch ($length) {
             case 160:
                 $length = 192;
                 break;
             case 224:
                 $length = 256;
         }
         parent::setKeyLength($length);
     }
