altering the label of a certificate

I am trying to update the label of a certificate I have in a .cer file on windows, per the instructions at http://l3.hursley.ibm.com/cgi-bin/ViewPRB.pl?standard/1032.prb&CO272005#keyman
These instructions talk about changing the label for a file in pkcs12 format, but don't say whether or not it is possible to change the label of a certificate that has been exported without its private key as a .cer type file. Since Keyman does not have any apparent help facility, I am trying to get a quick answer to this question: Can keyman be used to change the label of a certificate that has been exported into a .cer file, i.e., without its private key?
Thanks,
Tom

I am by no means an expert, but I would venture to say that what you are asking isn't possible. A certificate is basically immutable. It's a blob of data signed by a CA and if you change anything about it then the signature will no longer validate and the certificate will be destroyed. The tool lets you change the "Friendly Name" of a certificate in a PKCS12/PFX file becuase it's an external attribute to the certificate that describes it. A .cer file is usually a DER (binary) encoded certificate and nothing else.
