Methods summary

`public null\|string`	# `resizeKey( string $key, integer $size )` Trims or zero-pads a key / IV Trims or zero-pads a key / IV Parameters `$key` `string` - $key The key or IV to treat `$size` `integer` - $size The block size of the currently used algorithm Returns `null\|string` - Null if $key is null, treated string of $size byte length otherwise
`protected string`	# `getZeroPadding( string $string, integer $blockSize )` Returns null bytes to append to the string so that it's zero padded to the specified block size Returns null bytes to append to the string so that it's zero padded to the specified block size Parameters `$string` `string` - $string The binary string which will be zero padded `$blockSize` `integer` - $blockSize The block size Returns `string` - The zero bytes to append to the string to zero pad it to $blockSize
