I have a question about the md5 hash.

I have seen some of the code but I dont understand on what the
calculation being done in literal works.
to explain myself.

I do know that it uses the url and the method to hash for the key.
so there is a public and private keys.
private is method+url+id
public is url+method.
the method\function uses this api:
SquidMD5Update(&M, (unsigned char *) url, strlen(url));
the internals of the function is a bit high for me so to translate it
for me:
let say in ruby i'm using:
digest = Digest::MD5.hexdigest("Hello World\n")
=> "e59ff97941044f85df5297e1c302d260"

is there any way to translate a url + method hash into ruby?
a specific example is:
2012/09/11 18:37:45.949| storeKeypublicwith URL and method: GET
http://laptope:3128/squid-internal-static/icons/silk/page_world.png
2012/09/11 18:37:45.949| storeGet: looking up
E3F08214F440DC108204575CF98E2054

I can try to do some thinks in the code that will show me each time the
two options but I prefer to understand and plan what i'm suppose to see
which will help me.

Thanks in advance,
Eliezer
