SHA256/MD5 of IOS image verification

[Janice2]

Hello!

So I can't find that on software.cisco.com - seems like only a few of hashes are available there? Or am I just unable to use that website?
I have these old IOS images that I bought long time ago, but I'd like to verify its SHA256/MD5 hashes to make sure the files weren't corrupted/changed. Is someone able to find/maybe you have/or maybe you can guide me how to find a SHA256 of the following IOS images, please?

1.) c7200-adventerprisek9-mz.124-24.T5.image
2.) i86bi-linux-l2-adventerprisek9-15.1a.bin
3.) i86bi-linux-l3-tpgen-adventerprisek9-12.4.bin
4.) i86bi-linux-l3-jk9s-15.0.1.bin
5.) c3725-adventerprisek9-mz.124-15.T14.image

Hello @Janice2 

On Cisco Website "https://software.cisco.com/" you can see SHA512/MD5 Checksum of different IOS

Example:

With a MD5 checksum tool you can compare.

Well, thanks, but that's the thing I know and stated above. However I am unable to find checksums for these devices: Routers 7206 and 3725 + Switch Catalyst 3560.

So, Follow please, @Flavio Miranda explanation.

@Janice2 

verify md5 is a command you can run in IOS. You can use the checksum cisco provide on the download page. But, you are not going to find on cisco page because those IOS you listed is not available anymore and two of them is not IOS really.Those are IOU Stable Images

Using the IOS command line

Router# verify /md5 disk1:c7200-js-mz <checksum>

This url seems to check md5, never tested.

Exactly. The only thing that I really need is the official checksums from Cisco, but those IOS are no longer supported/available and I can't find them.

[Flavio Miranda]

That´s right. No longer exist.
