You want to make it write text or files? Im not sure what you're trying to ask here...

@4, like I said, its kinda pointless, and very limited.

@6, And I have shown that, time and time again, BGT's encryption is incredibly easy to break, owing to the poor way it manages memory. You have to do very weird hacks to get it to the point where its as good as OpenSSL would be, for example. And your forgetting that, while the BGT string_encrypt() function says it uses the "AES-Rijndel 256-bit encryption algorithm," it does not specify what mode it uses. So we don't know if it uses CBC, GCM, and so on. So getting PHP strings to be decryptable by BGT, and vice-versa, would be difficult because he'd need to try every single mode, and encryption is a tricky business anyway. Add to that the fact that AES is slow in software if you don't have AES-NI support in your processor, and that AES is very hard to implement correctly and securely, and you've got a disaster just waiting to happen. We don't even know if BGT has a custom-made AES encryption algorithm implementation or whether it uses a trusted AES encryption algorithm that has been shown to be securely implemented. If it does in fact use a custom algorithm, then I doubt PHP would be able to decrypt it, especially if that custom algorithm adds extra padding and all that, which may or may not compromise the security of the algorithm. PHP uses OpenSSL (or an equivalent) for its cryptography needs. We don't know what BGT uses.

And yeah i get your point about it not always working thanks to encryption being a bitch, but i guess just don’t try sending important data like that.
