Topic awaiting preservation: Encryption alogorithms (Page 1 of 1)

Now, I know that there are alot of encryption algorithms out there, but essentially what I'm looking for at the moment are the ones that work like MD5 or Blowfish, that take a short input string and convert it to a different string. How many of them are there out there? And where can I find information on how ot form their algorhithms in the programs I write?

You see, I'm currently learning Java, and for some reason today the urge struck me to write a program that will take an input string and give you an MD5 hash, and a blowfish hash, etc, for everything I could make it do. And for my own learning purposes I wanted to form those algorithms from the ground up. Any help here would be appreciated, in the form of 'well for this algorithm look at this site, ro do this' or 'your crazy, give up now!...but if you're not going to, try this site.' Any help, really

I use an encryption utility called FineCrypt that can encrypt using:

AES
Blowfish
CAST-256
GOST
Square
Mars
RC-6
Serpent
TripleDES
Twofish

Find a copy of the book "Numerical Recipes'. It has a chapter on encryption and how it works.

... You might try ROT-13 ...

... you might even try encrypting in it twice!

But ROT13 doesn't teach you anything by writing it...

You're looking for something like MD5 and blowfish?

They are not the same, MD5 is a hashing algorithm while blowfish is an encryption algo.
One is reversible, the other is not.

Please google about "Hashing functions" then "encryption algorithms"

Hope that helps
