Encrypts a message.<br /><br /><p>$plaintext will be padded with up to 16 additional bytes. Other AES implementations may or may not pad in the same manner. Other common approaches to padding and the reasons why it's necessary are discussed in the following URL:</p><p><a href="http://www.di-mgt.com.au/cryptopad.html">http://www.di-mgt.com.au/cryptopad.html</a></p><p>An alternative to padding is to, separately, send the length of the file. This is what SSH, in fact, does. strlen($plaintext) will still need to be a multiple of 16, however, arbitrary values can be added to make it that length.</p><br /><br /><br />
