How can I extract multiple keys into a single armored file with the command line PGP?
A number of people have more than one public key that they would like to make available. One way of doing this is executing the -kxa command for each key you wish to extract from the key ring into separate armored files, then appending all the individual files into a single long file with multiple armored blocks. This is not as convenient as having all of your keys in a single armored block. Unfortunately, the present version of PGP does not allow you to do this directly. Fortunately, there is an indirect way to do it.
