UW/IST CA -- Verification

1998/06/30-2007/09/24

Each digital certificate has a unique signature -- often called a fingerprint (e.g., by Firefox) or a thumbprint (e.g., by MS/IE). To verify that you've loaded the Certificate for the UW/IST Certificate Authority you'll need to find the certificate within your browser's store of certificates and then check the signature.

  1. The UW/IST (2007) CA fingerprint and thumbprint are:

    Fingerprint: 97:FD:6A:BF:59:1A:A8:74:F6:F3:F7:56:BA:80:10:02
    Thumbprint(sha1): 2C4F 44FD 7D20 8D57 AC6D 319F 2AF0 D7B4 2B4B F82D

  2. The UW/IST (1998) CA fingerprint and thumbprint are:

    Fingerprint: 0C:E6:37:89:28:B8:7A:D5:08:22:21:06:51:4F:44:E4
    Thumbprint(sha1): 55A6 7FF7 02D0 E6B8 43D8 525F 50CF F4CA C90D C8B0
If the signature of the certificate you have loaded into your browser doesn't match then you have loaded the wrong certificate (perhaps a forgery) and you should not trust it! In general you need not worry -- it's not very likely that you will have loaded the wrong certificate. However, there is a small (but real) possiblity that you may have.

These instructions are for the cautious who are concerned about that small possiblity. If you are concerned then you should check the fingerprint. If you need help in finding the certificate in your browser then follow the instructions for Netscape/Navigator and/or Microsoft/Internet Explorer as appropriate for the browser you're using.

If you are very cautious you ought to determine the correct fingerprint by other methods -- there's a small (but real) possiblity that this Web page might be a forgery! If you mail to the UW/IST CA they will be happy to confirm that the fingerprint here is correct.
