I have some hashes length 172 characters

e.g.
Code:

vEu+JxbYYGrdbg1AFNnxeFafzAZ7eBpWQZsZtT+WHNYp5WE6/v1zKn7nUMNBy+d/MtuHZ51F8qv75kO5q15scRc+cCDvBpy5RlSkX4cuiC29Wb/b42BAvNe56rsf5qHCN4nHmITrfGqu0cS/HPaAKC9M+WL3tqYWH6nS3yXF0as=


I know what goes in to make the hash (it is a signature on (account, data_str, number, time) its on a website javascript or ASPX...

I want to emulate it. Does anyone know what type of hash algorithm produces this and if I can get it in Perl or something?

From a glance it looked like Base64, but trying to decode it with that did nothing.

I'm not sure. Are the hashes variable length or fixed length? That'd be a good starting point. It's just very hard to guess from one single example.

Base 64 returns some weird binary file, but I'm not that enrolled in that kind of things I'm afraid Confused

Thanks for the comments.

I think it is proporitary activeX IE addon that generates it.
It always seems to be 172 characters, with variable length input string - the parameters passed are just strung together and then passed to the signing function.

I will try to call it from perlscript and see how I get on - that will save me emulating it - if I can just call the real one!
