Methods summary

`public Crypt_AES`	# `Crypt_AES( optional $mode = CRYPT_AES_MODE_CBC )` Default Constructor. Default Constructor. Determines whether or not the mcrypt extension should be used. $mode should only, at present, be CRYPT_AES_MODE_ECB or CRYPT_AES_MODE_CBC. If not explictly set, CRYPT_AES_MODE_CBC will be used. Parameters `$mode` `optional` Integer $mode Returns `Crypt_AES`
`public`	# `setBlockLength( Integer $length )` Dummy function Dummy function Since Crypt_AES extends Crypt_Rijndael, this function is, technically, available, but it doesn't do anything. Parameters `$length` `Integer` $length Overrides `Crypt_Rijndael::setBlockLength`
`public`	# `setIV( String $iv )` Sets the initialization vector. (optional) Sets the initialization vector. (optional) SetIV is not required when CRYPT_RIJNDAEL_MODE_ECB is being used. If not explictly set, it'll be assumed to be all zero's. Parameters `$iv` `String` $iv Overrides `Crypt_Rijndael::setIV`
`public`	# `encrypt( String $plaintext )` Encrypts a message. Encrypts a message. $plaintext will be padded with up to 16 additional bytes. Other AES implementations may or may not pad in the same manner. Other common approaches to padding and the reasons why it's necessary are discussed in the following URL: http://www.di-mgt.com.au/cryptopad.html An alternative to padding is to, separately, send the length of the file. This is what SSH, in fact, does. strlen($plaintext) will still need to be a multiple of 16, however, arbitrary values can be added to make it that length. Parameters `$plaintext` `String` $plaintext See `Crypt_AES::decrypt()` Overrides `Crypt_Rijndael::encrypt`
`public`	# `decrypt( String $ciphertext )` Decrypts a message. Decrypts a message. If strlen($ciphertext) is not a multiple of 16, null bytes will be added to the end of the string until it is. Parameters `$ciphertext` `String` $ciphertext See `Crypt_AES::encrypt()` Overrides `Crypt_Rijndael::decrypt`
`public`	# `_mcryptSetup( )` Setup mcrypt Setup mcrypt Validates all the variables.
`public String`	# `_encryptBlock( String $in )` Encrypts a block Encrypts a block Optimized over Crypt_Rijndael's implementation by means of loop unrolling. Parameters `$in` `String` $in Returns `String` See `Crypt_Rijndael::_encryptBlock()` Overrides `Crypt_Rijndael::_encryptBlock`
`public String`	# `_decryptBlock( String $in )` Decrypts a block Decrypts a block Optimized over Crypt_Rijndael's implementation by means of loop unrolling. Parameters `$in` `String` $in Returns `String` See `Crypt_Rijndael::_decryptBlock()` Overrides `Crypt_Rijndael::_decryptBlock`

Properties summary

`public String`	`$enmcrypt`	# mcrypt resource for encryption mcrypt resource for encryption The mcrypt resource can be recreated every time something needs to be created or it can be created just once. Since mcrypt operates in continuous mode, by default, it'll need to be recreated when in non-continuous mode. See `Crypt_AES::encrypt()`
`public String`	`$demcrypt`	# mcrypt resource for decryption mcrypt resource for decryption The mcrypt resource can be recreated every time something needs to be created or it can be created just once. Since mcrypt operates in continuous mode, by default, it'll need to be recreated when in non-continuous mode. See `Crypt_AES::decrypt()`
`public String`	`$ecb`	# mcrypt resource for CFB mode mcrypt resource for CFB mode See `Crypt_AES::encrypt()` `Crypt_AES::decrypt()`
