Re: [Gnumed-devel] GNotary

[Syan Tan]

How does gnotary prevent the timestamps in signatures from being altered at a

time , or 
a stored signature of an original document be replaced with a different 
signature of a different document at some other time , and that altered 
signature 
also being passed on to colluding client ?
