Good Encryption encoder/decoder

[fortgrizz]

Hi Im kinda new at encryption and was wondering if any one new of a good free or inexpensive encryption encoder/decoder I could download. Currently I am trying to decipher this, eb5feccbdc5d78ecd*cb6b*a*8255cba. Could someone tell me what type of encryption this is? (also if you want to go ahead and crack it for me that would be great!)

still trying to crack it, so far Im having no luck. Just found out its not md5 either. I dont know if I mentioned this before, but it was located inside a cookie

The admins at HEMU.co.nr might know...

I'm positive it's MD5. If you found it in a cookie, it usually is MD5.

It's not mandatory that the length of the string be a square number, but when it is it's a lot easier. Also, it's a much more interesting problem to solve when allowing for any length string.

To be efficient, I want to just work with a character array and not try to construct a 2-D array of char. For non-square number length strings, padding needs to be inserted to get to the square number length.
