What's the best way to verify the SHA1 and MD5 Finger print of the certificate uploaded to Wireless controllers 5500 & WiSM?

I've used Open SSL to get the signature of the file but a number of controllers have different signatures is it possible that the file has slightly changed in transit during a TFTP upload?

 

SHA-1 Hash

openssl x509 -fingerprint -noout -in certificate.pem

 

MD5 Hash

openssl dgst -md5 certificate.pem

It's a really strange.. I upload the certificate the SHA-1 hash checks out , MD5 doesn't. Give it a couple of minutes and they are both different. Is there some process on the device changing the certificate fingerprints? 

Is this a bug?
