I am so done for today. I was trying to get this encryption work in Rust, but no fucking way. If I encrypt data in PHP, it is just impossible to decrypt them in Rust. If I encrypt something in Rust, I can decrypt it anywhere, but not the other way around.
I checked the data hundred times and they are exactly the same in both programs. Also OpenSSL library in Rust is so helpful, that it won't show any error details except that there is an error.
Fuck my life!
