MD5 hash of Cisco IOS

Does anyone know where I can see the MD5 hashes of downloaded IOS' ?

I try to find out whether one downloaded IOS is corrupt or the flash (as extraction fails)

Great little utility - I do mean little LOL

HashCheck Shell Extension

verify <file name>. Like this:

verify flash:c2800nm-spservicesk9-mz.124-9.T5.bin

Done!
Embedded Hash MD5 : D85583DAB5ED006FF55D61957CE80078
Computed Hash MD5 : D85583DAB5ED006FF55D61957CE80078
CCO Hash MD5 : A2BA58CADDAE03B9EDE5562EA739448B

You should see a lot of dots while the router is calculating the values.

Thanks.

But doesn't it require for the system to be up in the first place ? The system doesn't have any other images on the flash right now so it cannot boot.

Does anyone have a 3725 and could send me a hash value of a specific IOS (can either post filename here or PM)
