Type of encryption used

I've been trying to decrypt this PHP page that I downloaded from some script hosting site, I need to change some info in it, and haven't been able to find what type of encryption it is.

Any ideas of what type it is? Any help would be much appreciated. :) The contents of the encrypted page:

It says what it does right there in the source.

I've tried decoding it with Yellowpipe's Base 64 decoder, it didn't seem to work out, the "decrypted" version just looked a bit fucked up and not right at all. Lol.

If you don't understand PHP, don't attempt to reverse engineer an encoded file (poorly encoded at that).

Now that's a crappy protection. I can't believe people are stupid enough to throw their money on shit like that.

I was bored, so I wrote a writeup on exactly how you can reverse engineer the obfuscation used by PHPLockIt. I think it needs to be demonstrated just how insecure that application is, and I learned a few new PHP functions along the way. Maybe someone else will find the writeup interesting, so you guys can check it out below if you want ^.^

@OP - I used your text in my writeup, and you can find the decoded PHP code in the article if you'd like.

There is a tweet button at the bottom of all my articles, if that's what you meant.
