Global check of input/output of known hash functions

Question

Is there a website, application, or script that will allow you to give an input/output for a hash function, run these against known functions, and return any matches?

Here's one attempt to list the functions:

Hash ID is a new, open sourced, project trying to achieve exactly the thing that you are looking for:

Answer 2

You might be interested in sphlib: this is a library implementing many cryptographic hash functions under a common API, and there is a command-line tool tool which ressembles the classic md5sum / sha1sum. It is written in C, but there is also a Java version which would be rather easy to turn into an applet for a Web site.

Answer 3

You mean that you want to give the input and the output, and then a site / app / whatever gives you what hash function was used?

I don't know any that does exactly that. But there is the http://www.fileformat.info/tool/hash.htm that calculates a lots of hashes formats for a given input. It gives you:

Adler32
CRC32
Haval
MD2
MD4
MD5
RipeMD128
RipeMD160
SHA-1
SHA-256
SHA-384
SHA-512
Tiger
Whirlpool
