Is there a hash function that returns a 16-digit hex value (as MD5 returns 32-digit), or is there a library (for C++) in which I can use MD5 or SHA-1 which returns a 16-digit value

I have an instance of dict with ints, floats, strings as keys, but the problem is when there are a as int and b as float, and float(a) == b, then their hash values are the same, and thats what I do NOT want to get because I need unique hash vales for this cases in order to get corresponding values…

Hi, I would like to construct a hash table that looks up keys in sequences (strings) of bytes ranging from 1 to 15 bytes.
I would like to store an integer value, so I imagine an array for hashing would suffice. I'm having difficulty conceptualizing how to construct a hash function such that given…

Theoretically does hashing a unique value yield a unique value?
Let's say I have a DB table with 2 columns: id and code. id is an auto-incrementing int and code is a varchar. If I do ...
$code = sha1($id);
... and then store $code into the same row as $id. Will my code column be unique as well…

I attempted to install the perl module Net::Twitter::Role::API::Lists using WHM and after doing so my whole site came down. It seems that something that was updated with the install isn't functioning correctly and since our website it written in Perl none of our site scripts will run.
In almost 8…

Hi all,
I'm trying to compare an MD5 checksum generated by PHP to one generated by Oracle 10g. However it seems I'm comparing apples to oranges.
Here's what I did to test the comparison:
//md5 tests
//php md5
print md5('testingthemd5function');
print '<br/><br/>';
//oracle…

Hello,
I was given this Python code that would calculate an MD5 value for any phrase:
import md5
md5.new("Nobody inspects the spammish repetition").digest()
(The phrase here is: "Nobody inspects the spammish repetition")
What I want to do is display this value in my browser. How do I do it in…

Im aware that MD5 has had some collisions but this is more of a high level question about hashing functions. If MD5 hashes any arbitrary string into a 32-digit hex value, then according to the Pigeonhole Principle surely this can not be unique as there are more unique arbitrary strings than there…

How can I convert the hashed result, which a byte array, to a string?
byte[] bytePassword = Encoding.UTF8.GetBytes(password);
using (MD5 md5 = MD5.Create())
{
byte[] byteHashedPassword = md5.ComputeHash(bytePassword);
}
So I need to convert…
