Methods summary
`public static`	# `dependencyCheck( type $throw )` Checks dependencies. Checks dependencies. Parameters `$throw` `type` $throw Throw an exception if this is set to true and dependencies are missing. Throws `Exception`
`public static string\|boolean`	# `genKey( integer $length = 32 )` Generates a new encryption key Generates a new encryption key Parameters `$length` `integer` $length Returns `string\|boolean`
`public static`	# `genIV( )`
`public`	# `__construct( mixed $keyFile = null, mixed $IVFile = null, mixed $throw = true )`
`public string`	# `__get( mixed $name )` Magic getter that obtains a value for an attribute from a file, or by generating new values. Magic getter that obtains a value for an attribute from a file, or by generating new values. The assumption is made: if no storage files are specified, the instance creates new keys for a single usage without complaining, and does not store them. Otherwise, if files are specified but do not exist, a new encryption key is generated (to be stored when `EncryptUtilTmp::saveNew()` is called). Returns `string` Throws `Exception`
`public`	# `__set( mixed $name, mixed $value )`
`public`	# `encrypt( mixed $data )` Encrypts data. Encrypts data.
`public`	# `decrypt( mixed $data )` Decrypts data. Decrypts data.
`public type`	# `saveNew( type $safe = true )` Generates and saves an encryption key/IV length in files specified by _keyFile and _IVFile. Throws an exception if the key couldn't be made securely. Generates and saves an encryption key/IV length in files specified by _keyFile and _IVFile. Throws an exception if the key couldn't be made securely. Parameters `$safe` `type` $safe Returns `type` Throws `Exception`
