Wonderful! Could I have an usage example? I tried your script and I got a "Call to undefined function: aes_encrypt() on line 108" I suppose I need the PHP extension too ;-) > I will have a closer look, if a implementation in PHP can > be done with acceptable performance and in acceptable > time. Crypt_AES could then fallback to the PHP implementation > of no ext/aes is available. That would be just *perfect*. I could help with porting from C source, if you can't do it alone. Just assign me my homeworks :-) > XML_Encryption is a class to handle encrypted XML files? Right... It takes the value to encrypt, some options such as algorithm to use, additional parameters, key value/location, etc, and builds the XML [ EncryptedData | EncryptedKey ] block. I'm also planning a decryption class, but I need those algorithms first... After that, XML Digital Signature could be considered ;-) Tnx, Lorenzo
