Hi,
Maybe somebody can help me with these two questings.
1. Why do all the certificates I see have a leading zero in the
"modulus" value of the public key. I suspect that some software
even starts behave buggy when this is not present. I thought that
the "modulus" value was stored as a der encoded integer (not
bitstring) so why this zero?
2. What is the algorithm to calculate a certificate fingerprint.
I have looked in various places but can't find a definition,
eventhough applications dealing with certificates (like
netscape) allways show this fingerprint.
thanks,
Jeroen
