@johan: can you refer me to a tutorial on how to do single file encryption? Googled a bit already, but most seem to focus on encrypting with public / private keys, which means you have to have certificates etc. I suppose there is also a stand-alone mode to encrypt individual files with a password - or do you always need a certificate? If so how do you deal with certificates - e.g. the risk of loosing them and thereby being locked out of the data ?
