Re: [Duplicity-talk] duplicity incr - private key missing

[edgar . soldin]

I remember to have read that no private key is necessary anymore. So my memory 
fails here.

Unless this comparison is dealt differently (maybe in a future duplicity?) at 
least one private key for a key used to encrypt has to reside on the duplicity 
box?
