Use fork of hsdecomp to understand that the following is occurring:
* Input string is taken from stdin* Current UTC time is retrieved, converted to POSIX time, and floored to seconds* POSIX time in seconds is used to seed a Xorshift32 generator function* Each byte in the input string is XOR’d with a 0xff-masked integer generated from the Xorshift32 function* Final output is converted to characters, packed together and printed
