How to use Digital Signatures
Do they service a useful purpose?
I wanted to test something else out on my machine, so I backed up my system with DriveImage. within VBA I looked in Tools - Digital Signature - Choose I had no certificates Then installed selfcert, made a certificate, attached it to a spreadsheet via Choose, saved it to floppy I then restored my system, checked in Choose, and there were no certificates, but when I opened my spreadsheet it told me it was signed without the need for the certificate I thought the idea of certificates were to install them into the trusted source or whatever. I can't really see how I can genuinely trust certificates that have my name in cos they may be forged and it just seems like a variation on the theme that "this spreadsheet contains macros" Is there a better way of managing Digital Signatures so only I can install certificate, and only files signed with that certificate can be trusted -- Mike Please post replies to newsgroup to benefit others Replace dead spam with ntl world to reply by email |

How to use Digital Signatures
Mike,
The obvious answer is to purchase it from Verisign. It's about $450 a year. But hopefully someone provides you a cheaper way because I would have an interest too.
