can someone help me understand?

This code means nothing. It shall not be compiled.

[DANNY123]

Is that some bitwise code?

[Smac89]

Very obfuscated code. And yes it pretty much makes use of all the bitwise operators available. There is a for-loop in there somewhere don't be confused with the strings; in obfuscated code, anything could mean anything
