Can these files be decrypted?

Hi,

I'd like to see if you can decrypt these files before I use your service. Just a sample from each file is fine, I will know if it's the correct file.

I don't know what php version they are or the ioncube version.

Also, do you sell the decoder? If so, do you send updates? Will you ever stop developing it?

Here are the files:

Thanks!
