Sorry, again, I am self-taught when it comes to coding, I do not fully understand the pseudocode... From what I understand I have to change "8044d00f6eb2e5491cd7ab7e7185d81b67a23c4980f62b2ed0914d32b7eb1c55815b0e9051" into a "big integer" and then perform some math on it. How do i convert a plain text string to a "big integer"?
It means treat that hex string as a really big integer encoded in hex (base16). The easiest thing is to go to a site like
http://www.wolframalpha.com/ and type that string followed by " convert to decimal" and it will give you a really large decimal integer. Then you just use that number to do the conversions.
Also, when working with hex, you always need to think of hex not as a string but as bytes and integers.
