Hi,

I would like to correct myself about using GCM and CCM in PHP. These modes are available for encryption/decryption but there is no way how to get an authentication tag. That's a bit problem as it doesn't make sense to use gcm or ccm if you can't get a tag... On top of it the AAD (Additional Authentication Data) can't be set either... I decided to fix that in php-crypto. I have created an issue about PHP API for this modes: https://github.com/bukka/php-crypto/issues/4 . There are two ideas how the API could be designed. It would be very helpful for me to get any feedback as it could result in more usable API. There also are two other issues in https://github.com/bukka/php-crypto/issues . The first is about API for Algorithm class and the second is about choosing a name for the method that create a digest in one step (currenty Digest::make that is not really explaining...). All issues are just about PHP user interface for this extension (there is nothing about internal C implementation). In addition if anyone knows about any objective crypto library that he used in past and thinks that some ideas could be used in this extension, please let me know. I was looking to Zend\Crypt and also plan to properly look to crypto++. Thanks Jakub
